FCC ID: PPJSD4418SC

General Description:

The Model SD4-MC(US) photocell electronic smoke detector with built-

in wireless transmitter is intended for use with the Silent Call® Mini

receiver to form an alerting system. The transmitter will send alarm

condition messages to the system’s receiver.

The SD4-MC(US) wireless transmitter operation is to be used only

with Silent Call® Medallion Series Receivers. The transmitted signal

incorporates a Million Code Address principle that provides each SD4-

MC(US) detector with a unique one in a million address. This helps to

keep any cross talk between like transmitters in a typical single living,

multi-dwelling, or apartment building to a minimum where it is possible

to have adjacent apartments with Medallion Series Receivers.

IMPORTANT: The range and proper operation of any wireless device

will vary depending on its surroundings. It is very important that each

SD4-MC(US) detector is tested with each receiver intended for Alarm.

The Model SD4-MC(US) incorporates a state of the art optical sensing

chamber and an advanced microprocessor. The microprocessor allows

the detector to automatically maintain proper operation at factory cali-

brated detection levels, even when sensitivity is altered due to the pres-

ence of contaminants settling into the unit’s smoke chamber. In order

for this feature to work properly, the chamber must never be opened

while power is applied to the smoke detector.

This includes cleaning, maintenance or screen replacement.

The Model SD4-MC(US) contains a piezoelectric horn which generates

the ANSI S3.41 temporal pattern in an alarm condition. During an alarm

condition, pressing the detector’s test switch will silence the piezo-

electric horn for 5 minutes. The built-in Drift Compensation algorithm

automatically maintains the sensitivity of the detector. The mounting

base installation is simpliﬁ ed by the incorporation of features compat-

ible with drywall fasteners or other methods that provide a method for

securing the detector in place.

Current studies have shown smoke detectors may not awaken all

sleeping individuals, and that it is the responsibility of individuals in the

household that are capable of assisting others to provide assistance to

those who may not be awakened by the alarm sound, or those who may

be incapable of safely evacuating the area unassisted.

Two LEDs and a sounder on the detector provide local visual and audi-

ble indication of the detector’s status:

Power-up

Table 1: Detector LED Modes

During initial power-up, the red and green LEDs will blink synchronous-

ly once every 5 seconds. It will take approximately 20 seconds for the

detector to ﬁ nish the power-up cycle (see Table 1).

After the power-up cycle has been completed and the detector is

functioning normally within its listed sensitivity range, the green LED

blinks once every 10 seconds. If the detector is in need of maintenance

because its sensitivity has shifted outside the listed limits, the red LED

blinks once every 5 seconds. When the alarm has been activated by

smoke, the red LED blinks every 1 second. The LED indication must

not be used in place of the tests speciﬁ ed under Testing. If the detector

senses a low battery condition, the red LED blinks once every 45 sec-

onds.

Low Battery Detection:

The Model SD4-MC(US) is powered by a single 3-volt CR123A Lithium

battery. The detector checks for a low battery at least every 65 minutes.

In addition, the red LED of the Model SD4-MC(US) will blink every 45

seconds and the test switch will be disabled. This condition will exist for

a minimum of 7 days, and then the detector’s horn will “chirp” about

every 45 seconds. Pressing the test switch during this time will silence

the chirps for 12 hours. The battery should be replaced BEFORE the

chirps begin. Be sure to replace the battery with a fresh one. Batteries

can be purchased directly from Silent Call Communications by calling

1-800-572-5227, or online at www.silentcall.com.

Battery Life Expectancy:

Replace the battery once a year or immediately when the low battery

indicator starts to blink and the horn begins to chirp.

Battery Installation and Replacement:

To replace the battery:

1. Remove the detector from its mounting base by twisting the detec-

tor counterclockwise. Remove the battery and dispose of it

properly.

2. To ensure proper power-down sequence, wait a minimum of 20

seconds before installing new battery.

3. Install a new approved 3-volt Lithium battery in the battery com-

partment. Follow the polarity diagram inside the compartment.

4. Reinstall the smoke detector onto the mounting base by turning

the detector clockwise.

5. The green LED should blink about once every 10 seconds to indicate

normal operation. If the battery is not installed correctly, the smoke

detector will not operate and the battery may be damaged. If the

detector does not appear to be sending a signal during any of the

tests, check for correct battery installation and for a fully charged

battery.

6. Test Smoke detector operation with Medallion Series Receiver to

verify proper operation.

NFPA Required Protection:

This smoke detector should be installed in accordance with the Nation-

al Fire Protection Association, Standard 72 (National Fire Protection

Association, Quincy, MA 002269). This detector will provide maximum

Recommended Locations for Smoke Detectors:

The National Fire Protection Agency (NFPA) recommends one smoke

detector on every ﬂ oor, in every sleeping area, and in every bedroom. In

new construction, the smoke detectors must be AC powered and inter-

connected. For additional coverage, it is recommended that you install

a smoke detector in all rooms, halls, storage areas, ﬁ nished attics, and

basements where temperatures normally remain between 4.4°C to

37.8°C. Make sure no door or other obstruction could keep smoke from

reaching detectors.

Specifically locate detectors:

• On every level of your residence, including basements and ﬁ nished

attics.

• Inside every Bedroom, especially if people sleep with the doors

closed.

• Inside every bedroom where electrical appliances (such as portable

heaters or humidiﬁ ers) are operated where someone sleeps.

• At the bottom of the basement stairwell.

• At the top of the ﬁ rst-to-second ﬂ oor stairwell, as long as no other

door or other obstructions block the path of smoke to the detector

• As close to the center of the ceiling as possible. If this is not practi-

cal, put the detector on the ceiling, but no closer than 4 inches (10

cm) from any wall or corner. See ﬁ gure 1.

• If wall mounting is permitted by your local and state codes. Put the

top of wall-mounted detectors between 4 and 6 inches (10 and 15

Where Smoke Detectors Should Not Be Located:

Nuisance alarms are caused by placing detectors where they will not

operate properly. To avoid nuisance alarms, do not place detectors:

• In or near areas where combustion particles are normally present

such as kitchens, in garages where there are particles of combus-

tion from vehicle exhausts, near furnaces, hot water heaters, or gas

space heaters. Install detectors at least 20 feet (6 meters) away from

kitchens and any other areas where combustion particles are nor-

mally present.

• In air streams passing by kitchens. Figure 3 shows how a detector

can be exposed to combustion particles in normal air movement

paths, and how to correct this situation.

Figure 3: Recommended smoke detector locations to avoid air streams

with combustion particles.

• In damp or very humid areas, or next to bathrooms with showers.

The moisture in humid air can enter the sensing chamber as water

vapor, and will cool and condense into droplets that cause a nui-

sance alarm. Install detectors at least 5 feet (1.5 meters) away from

bathrooms.

• In very dusty or dirty areas. Dust and dirt can build up on the de-

tector sensing chamber and make it overly sensitive, or can block

openings to the sensing chamber and keep the detector from sens-

ing smoke.

• Near fresh air inlets or returns or excessively drafty areas. Air

conditioners, heaters, fans, and fresh air intakes and returns can

drive smoke away from smoke detectors, making the detectors less

effective.

• In dead air spaces at the top of a peaked roof or in the corners be-

tween ceilings and walls. Dead air may prevent smoke from reach-

ing the detector. See ﬁ gures 4 and 5 for recommended mounting

location.

• In insect-infested areas. If insects enter a detector’s sensing cham-

ber they may cause a nuisance alarm. Get rid of the bugs before

installing detectors where bugs are a problem.

• Near ﬂ orescent light ﬁ xtures. Electrical “noise” from nearby ﬂ ores-

cent light ﬁ xtures may cause a nuisance alarm. Install detectors at

least 10 feet (3 meters) away from such light ﬁ xtures.

Limitations of Smoke Alarms

• Smoke detectors will not work without power. Battery operated

detectors will not work without batteries, with dead batteries, or

if the batteries are not put in properly. AC-powered detectors will

not work if their AC power supply is cut off by an electrical ﬁ re,

and open fuse or circuit breaker, or for any other reason. If you are

concerned about the reliability of either batteries or your AC power

supply for any of the above reasons, you should install both battery

powered and AC powered detectors for maximum safety.

• Smoke detectors must be tested regularly to make sure the batteries

and the alarm circuits are in good operating condition.

• Smoke detectors may not sense ﬁ res that start where smoke cannot

reach the detectors such as in chimneys, in walls, on roofs, or on the

other side of closed doors. If bedroom doors are usually closed at

night, detectors should be placed in each bedroom as well as in the

common hallway between them.

• Smoke detectors also may not sense a ﬁ re on another level of the

residence or building. For example, a second-ﬂ oor detector may not

sense a ﬁ rst-ﬂ oor or basement ﬁ re. Therefore, detectors should be

placed on every level of a residence or building.

• The horn in your detector meets or exceeds current audibility

requirements of Underwriters Laboratories. However, if the detec-

tor is located outside a bedroom, it may not wake a sound sleeper,

especially if the bedroom door is closed or only partly open. If the

detector is located on a different level of the residence than the

bedrooms, it is even less likely to wake up people sleeping in the

bedrooms.

• All types of smoke detectors have limitations. No type of smoke

detector can sense every kind of ﬁ re every time. In general, detec-

tors may not always warn you about ﬁ red caused by carelessness

and safety hazards like smoking in bed, violent explosions, escaping

gas, improper storage of ﬂ ammable materials, overloaded electrical

circuits, children playing with matches or arson.

• Installing smoke detectors may make you eligible for lower insur-

ance rates, but smoke detectors are not a substitute for insurance.

Homeowners and renters should continue to insure their lives and

property.

Programming

The smoke detector is pre-programmed at the factory.

Transmitter Setting

The Silent Call® system is digitally coded. The Medallion Series SD4-

MC(US) Smoke Detector is set to a unique million code setting at the

factory and therefore never requires the need of a different code.

Transmitter operates at a frequency of 418MHz.

Mounting

First, determine the best location for the smoke detector, one that pro-

vides a strong wireless transmission path and proper smoke detection.

A GOOD TRANSMISSION PATH MUST BE ESTABLISHED FROM THE

PROPOSED MOUNTING LOCATION BEFORE PERMANENTLY INSTALL-

ING THE DETECTOR. To check, perform the test described in the TEST-

ING SIGNAL STRENGTH section of this manual. To mount the detector,

perform the following steps:

1. Once a suitable location has been determined, install the mounting

base on the ceiling or on the wall (if local ordinances permit). Use

the two screws and anchors provided.

2. Turn the detector in a clockwise direction in the mounting base until

it clicks into place.

3. Test the detector immediately after completing the installation as

described in the TESTING section of this manual.

Figure 5: Mount Detector Across Ceiling Panel Support.

DO NOT attach the detector to removable ceiling panels.

Attach the detector across panel support as shown in Figure 5.

Dust Covers are an effective way to limit the entry of dust into the

smoke detector sensing chamber during construction. However, they

may not completely prevent airborne dust particles from entering the

detector. Therefore, it is recommended that the detectors be removed

before beginning construction or other dust producing activity. When

returning the system to service, be sure to remove the dust covers from

any detectors that were left in place during construction.

Smoke detectors are not to be used with detector guards unless the

combination has been evaluated and found suitable for that purpose.

Testing the Sensor

Detectors must be tested after installation and following periodic main-

tenance. The Model #SD4-MC(US) may be tested as follows:

A. Test Switch

1. A recessed test switch is located on the detector housing

(see Figure 6).

2. Push and hold the recessed test switch for a minimum of 5 seconds.

Use a small screwdriver or Allen key with maximum diameter of

0.18 inch (the detector will trigger and then the smoke detector will

go into alarm thus sending a transmitting signal to the receiver. If

the tool is removed from the recessed switch the sounder will shut

off)

If the detector is within the listed sensitivity limits, the LED on the

detector should blink once per second and the horn should sound with-

in 3 seconds.

Hold a smoldering punk stick or cotton wick at the side of the detec-

tor and gently blow smoke through the detector until the unit alarms.

Canned aerosol is also an accepted method.

Figure 7: Testing with Wick

Testing Signal Strength

A test should be performed before installation to determine a strong

communication path with the receiver and after installation is complete.

Also the owner/user should test the unit at least weekly.

Testing Programming

A test should be performed before installation to ensure the detector

transmitter address is properly programmed to the receiver, and are

operational as a system.

Maintenance

NOTE: Power must be removed from the detector before performing

maintenance of any kind by removing the detector’s battery.

1. To ensure proper power-down sequence, battery must be removed

from detector for a minimum of 20 seconds before servicing.

2. Vacuum the cover or use canned air to remove any dust or debris.

3. Using a vacuum or canned air spray carefully clean any dust or de-

bris From Smoke Detector Cover.

4. Reinstall the detector and test. (see the Testing section).

What to do in case of fire

• Don’t panic; stay calm. Follow your family escape plan.

• Get of the house as quickly as possible. Don’t stop to get dressed or

collect anything.

• Feel doors with the back of your hand prior to opening them. If a

door is cool, open it slowly. Don’t open a hot door. Keep door and

windows closed, unless you must escape through them.

• Cover your nose and mouth with a cloth (preferably damp). Take

short shallow breaths.

• Meet at the planned meeting place outside your home, and take a

head count to make sure everybody got out safely.

• Call the ﬁ re department from outside. Give your address, then your

name.

• Never go back inside a burning building for any reason.

• Contact your ﬁ re department for suggestions and ideas on how to

make your home safer.
