SECURITRON MODEL XMS EXIT MOTION SENSOR

INSTALLATION AND OPERATING INSTRUCTIONS

1. DESCRIPTION

The XMS is a passive infrared motion detector specifically designed to release a magnetic lock

from the inside for free egress. Unlike burglar alarm type detectors, the XMSìhas special

features appropriate to this use. The lock control function is fail safe so that the magnetic

lock will safely release if power is cut to the detector. A relay is also present to send a REX

(request to exit) signal to an access control system (if one is present) and therefore shunt an

alarm report. A time extension feature avoids the problem of the unit resetting if a person

momentarily stops moving just before exit. Tight control of the exit detection pattern allows

maximum security from the outside and avoidance of inadvertent activation from the inside.

Since egress from a magnetically locked door can be a safety issue, make sure you are

complying with local building codes. Contact your building and/or fire prevention

department.

2. PHYSICAL INSTALLATION

2.1 PLACEMENT OF THE UNIT

The XMS is intended for indoor use only. It is positioned with respect to the inside of the door

so that its detection pattern will “see” a person approaching the door while maintaining good

security from the outside. There are different options as to where the unit is placed depending

on variables in the application.

The simplest method of placing the unit is for traffic control applications. A traffic control

application is one where you do not expect any attempt at breaking in from the outside. The

PN# 500-18000

Page 2 Rev. D, 10/11

unit is simply centrally positioned above the door with the pattern covering the door (setting the

pattern is addressed later in this manual).

For security applications, you will set your position to defend against someone activating the

detector from the outside. This can be done by inserting a heated object under the door. To

deal with this threat, the unit is positioned above and outside of the door hinges with the pattern

adjusted so that it sweeps across the door but does not detect the bottom of the door. If the

door includes an exit bar, the pattern must be broad as a person’s approach to the door is

variable. If it includes a door knob or lever handle, the pattern can be adjusted more

narrowly.. A final option for security applications is to position the unit at the side of the door

so that it sees across the door. This can be used for doors at the end of corridors. You would

not want to employ this approach for non corridor doors as the door would be released by

someone walking near it (maximum detection range is 20-25 ft.) Side of door mounting has the

disadvantage of greater exposure to vandalism but defends against objects being inserted under

the door and provides excellent coverage along the full width of the door. Note that for the end-

of-corridor application, the unit can be positioned on the same wall plane as the door or on a

wall which is next to the door and perpendicular to it. You have the choice because the pattern

can be adjusted a full 90 degrees with respect to the sensor’s mounting plane.

2.2 FIXING THE UNIT TO THE WALL

First, locate the screw on the end of the unit and loosen it. This permits you to remove the

cover. The appearance of the interior is shown in Figure 2. Note that the interior electronics is

mounted on a rotating barrel which is locked by the “Barrel Locking Screw” shown in Figure 2.

Loosen this screw and rotate the barrel fully upward so that you can remove it. This leaves you

with the back piece and you will see two slotted holes for physical mounting and a choice of two

wire entry points (also shown on Figure 2). Most installers prefer to pull the cable through the

wall first and then mount the unit. If you’re not sure of your wire count for the cable, consult

the next section at this time but completion of physical installation consists only of screwing the

back piece to the wall and pulling the cable through one of the wire entries. Then you will

replace the barrel assembly and attach the wires to the screw terminals.

3. WIRING

3.1 INPUT POWER

To power the unit, filtered and regulated DC voltage between 12 and 28 volts should be applied

to the power input terminals (see Figure 2). This connection should be permanently made to

the power supply rather than switched through some other device. The XMS should receive

constant power. Make sure you observe correct polarity with this connection. If you reverse

the input power polarity, the unit will not be damaged but will appear to be dead. Power

consumption for the XMS is approximately 20 mA.

3.2 WIRING WITH MAGNETIC LOCK ONLY

This is the simplest application which releases the magnetic lock from the inside for free egress

but is not concerned with shunting any alarm point at the door. It is shown in Figure 3.

Note that how positive power to the lock connects through the terminal block “IN+” and

“DEVICE”. These two terminals constitute an internal field effect transistor which does the

actual switching. If power to the XMS was somehow interrupted, the field effect transistor would

automatically open (releasing power to the lock). This makes the XMS “fail safe”. Note:

never use the REX relay contacts to switch the magnetic lock. These contacts only have

enough capacity for signaling; they cannot reliably switch magnetic lock current.

If you need to integrate a controlled entry unit such as a digital keypad, use a set of NC

contacts from the entry unit to break the wire between “DEVICE” and magnetic lock “+” to allow

the entry unit to release the lock.

3.3 SHUNTING AN ALARM POINT

This technique is for installations where the door is connected to an alarm system and that if

the door opens without the XMS having been activated, an alarm signal should result. When the

XMS is employed to open the door, the alarm signal should be shunted.

The alarm system will be connected to a door switch or other detector at the door via two wires.

You will need to determine if this “loop” is closed when the door is closed and opens when the

door opens or is open when the door is closed and closes when the door opens. Correct wiring

to shunt the alarm is shown in Figure 4 for either instance. You utilize the “REX” relay contacts

for this shunting while the lock control relay contacts continue to release the magnetic lock.

3.4 INTEGRATION WITH ACCESS CONTROL SYSTEM

An access control system permits entry (generally from a card reader) and will also often act as

an alarm system if a door is forced. To integrate with the XMS and a magnetic lock, the access

system should have a two-terminal REX (request to exit) input. When this input is closed, the

access system will operate its lock control relay to release the lock and will not create an alarm

signal as it will consider the exit event a “legal” one. Wiring is shown in Figure 5. Note that with

this wiring method, the lock control terminals of the XMS directly break power to the magnetic

lock as do the access system contacts. This is called “double break” wiring. It enhances safety

PN# 500-18000

Page 4 Rev. D, 10/11

and reliability as if the access system experiences a fault, the XMS still allows safe egress. If the

access system is not monitoring the door, connection to the REX input is not required. In that

case, make all other connections as shown in Figure 5 except the REX input.

3.5 “ACCESS CONTROLLED EGRESS DOOR”

In some jurisdictions, the combination of a magnetic lock, access control system and exit

detector such as the XMS can be considered an “access controlled egress door”. The applicable

section of the Life Safety Code calls for a redundant means of exit in the event of a problem with

the detector. This is typically a push button located 40-48” above the floor and within five ft. of

the door. Pushing the button will directly release power to the magnetic lock and the lock shall

remain released for 30 seconds. This can be accomplished with any of Securitron’s push buttons

and the model TM-8L timer. Figure 6 shows proper wiring.

Securitron also manufactures a line of push buttons with integrated timers (EEB2 and

EEB3N). These are easier to use with the XMS to satisfy the code requirements for access

controlled egress doors. Figure 7 shows wiring with the integrated push button/timers.

4. BASIC OPERATION

When the XMS is first powered, its LED will flash twice quickly every second for about 40

seconds. This is a self test and also permits the XMS to adjust itself to the thermal

environment that it “sees”. After this start up period, the LED will stay green. If the self test

fails during the start up period, the LED will begin to flash at four times per second. This failure

indication will continue indefinitely. If you see it, de-power the unit for about 30 seconds and

then re-power it. If the failure indication occurs again, replace the unit. During the self test

period the unit’s control outputs are in their “normal” conditions (lock control-conducting; REX-

relay deenergized).

In the event of a very brief power outage, the unit will not self test for 40 seconds but will

undergo a self test of 10 seconds before resuming normal operation. Note that the self test on

power up feature of the unit is the main reason why the XMS must receive constant power.

With the jumpers in factory set condition and the unit past its self test, it will detect moving

objects at a different temperature than ambient. It will signal this detection by switching its LED

from green to red. The LED actually mirrors the state of the REX relay rather than the lock

control transistor.

You need to understand how the unit’s control outputs operate in a detection event. In the rest

condition (green LED on; no detection), the lock control transistor is conducting and the

REX relay is deenergized. When an object is detected, the REX relay energizes immediately.

This is to shunt alarm contacts or send a REX signal to an access control system. Fifty

milliseconds later, the lock control transistor switches off which releases the magnetic lock.

This brief delay is to make sure that the access control system has processed the REX signal so

that it won’t alarm if it is also reading lock status detection such as Securitron’s Senstat feature.

A lock status signal will change state as soon as the lock is de-powered.

In factory set condition, the lock control transistor will remain off for four seconds after detection

has ceased (keeping the lock released). If, during the four seconds, the object moves again, the

detection condition will be maintained for another four seconds after this “new” detection ceases.

For the magnetic lock to resecure, four seconds must pass with no detection. This trailing

edge timing feature is for egress safety and reliability. Otherwise, it is possible for a person to

approach the door (thereby activating the XMS) but then stop moving for a brief moment at the

door. The detector would then reset and if the person then quickly lunged into the door he could

receive a bump as his motion could be quicker than the response of the detection to this new

movement. The four second timing feature virtually eliminates this potential problem. Another

operational safety feature is the fact that if power is cut to the XMS, the lock safely releases

so that a person wishing to exit is not trapped.

PN# 500-18000

Page 6 Rev. D, 10/11

Returning to operation of the REX relay, as we said earlier, it energizes 50 milliseconds before

the lock control transistor releases the lock. It remains energized as long as the lock control

transistor is continuing to release the lock. When the lock resecures, the REX relay will remain

energized for one additional second to allow the magnetic lock to fully engage and report secure

in the event that it is reporting lock status to an access control system.

The four second timing feature of the lock control relay can be altered by changing jumper

settings (see Section 5) but the REX relay always operates 50 milliseconds before and one

second after the lock control transistor. Figure 8 shows the timing sequences.

5. JUMPER SETTINGS

Refer to Figure 2 and note that there are 3 jumpers. They are depicted in factory set condition.

The LED logic jumper controls the logic of the bi-color LED. When left in factory set position

(jumper installed), the LED will illuminate red during a detection event and return to green in

the rest condition. Removing the jumper will reverse these colors.

The sensitivity jumper makes the unit sensitive to movement in the factory set condition

(jumper installed). It will become less sensitive when the jumper is removed. This is

sometimes advised when the unit is mounted with a loosely fitting door that leads to the exterior

of the building. If air, at a different temperature from the interior, is able to blow in

from the gaps in the loosely fitting door, the XMS may “see” this. The lock will therefore

be occasionally released with no one present. Removal of the jumper can correct the problem at

the cost of a bit slower operation. Other techniques include physically locating the unit farther

from the edges of the door and adding weather-stripping to the door.

PN# 500-18000

Page 7 Rev. D, 10/11

The time set jumper can be installed in any of three positions to

alter the factory set trailing edge delay of four seconds. The drawing

to the right shows the three choices. Four seconds is right for most

applications. 1/2 second is used for pattern set-up (see Section 6)

and certain applications where an external timer should replace the

XMS timer. For example, when the XMS is integrated with an

access control system (see Section 3.4), the XMS’s REX relay will

trigger the access system’s lock control relay and the magnetic lock

will release for the same amount of time that is programmed for

entry. If the set jumper is installed for the 1/2 second setting and

assuming a person is initially sensed by the XMS, then does not

immediately exit but moves around in front of the door, they will

continue to retrip the XMS. Persistant retripping of the XMS however,

will cause the Lock Control and REX Relay to remain latched until no movement is sensed for a

time greater than the set 1/2 second. It is important to note that this device has a “trailing

edge” delay – i.e. the device Lock Control and REX Relay will remain latched until a time

greater than the set time has expired since the last detected movement. If you used the

four second setting on the XMS for integration with an access control system, you would risk the

following problem. On initial detection, the access system starts timing for 10 seconds (as an

example) But the person does not immediately exit but moves around in front of the door so

that the XMS signal does not change but stays closed because of the four second timing

function. This allows the access system’s 10 second timer to time out and if the door is then

used, a “forced door” alarm signal will result. So the 1/2 second setting is right for integration

with access control systems.

Another application where you should employ the 1/2 second setting is when the XMS is

employed to initiate delayed exit when you are using Securitron’s model XDT timer.

The eight second setting is rarely used unless there is strong concern for maximum time being

allocated for egress even when movement is not maintained. The problem with an eight second

trailing edge delay is that entry security begins to be compromised by the door remaining open

for this length of time following exit.

6. DETECTION PATTERN SET-UP

At this point in the installation, the unit should be physically mounted and wired.

You should have also considered changing the jumper settings. Your final step is to

adjust the detection pattern for the optimum combination of egress safety and entry

security. Before doing this, set the time set jumper to the 1/2 second position

(shown in the drawing to the right). As you are adjusting the pattern, you will make

many quick tests of the unit and this will be most efficient if you don’t have to wait for a four or

eight second trailing edge timer to expire.

The XMS provides two means of adjustment. First, the entire barrel

assembly rotates 90 degrees so that the unit can look “out” or “down”.

Second, aiming screws (see Figure 2) are provided to laterally control the

pattern. To access the aiming screws, the barrel assembly must be

rotated so that the unit looks “out” so while you are making these

adjustments, you will need the barrel locking screw (see Figure 2) to be

loose.

In most applications, the unit is set to look “down”. The exception would

be if the XMS was mounted on a wall perpendicular to the door rather

than parallel to it. As the detection pattern proceeds outward from the

XMS it spreads. We are talking here about spreading in the same

direction as the barrel rotation rather than lateral spreading which is

constrained by the aiming screws. The drawing on the right provides an

example of this spreading. Assuming the XMS is mounted seven feet

above the floor, the pattern will spread out roughly three feet by the time it reaches the floor.

Maximum detection distance is approximately 20 feet.

The aiming screws are used as follows. They control internal louvers that point the same way

as the slots in the screws. When adjusting these screws, do not turn them past the point where

you feel resistance as they can take the louvers “off track”. Figure 9 shows the typical

relationship between the aiming screw orientation and the resultant detection pattern.

To set your pattern laterally, experiment with the aiming screws as is shown in Figure 9. Each

time you alter the aiming screw setting, you will have to rotate the barrel assembly up and

down. Test the pattern by moving in it and observing the limits of detection by watching the

LED. When you are satisfied with the aiming screw settings, you must also finalize the degree of

barrel assembly rotation. You don’t want the unit “seeing” the surface of the door itself as this

can lead to false detection, so in the common case where the unit mounts in the same plane as

the door, you do not want the barrel assembly adjusted at full 90 degrees. It should face

slightly away from the door.

When you are entirely satisfied, be sure to tighten the barrel locking screw and restore the time

set jumper to the four second position (if necessary). Then replace the cover.
