Ultra•Max detectors and deactivators derive their
timing from the zero crossing of the ac power line.
Ultra•Max detectors and deactivators may interfere
with each other if there are ac line phasing
differences between systems.
The Phasing tool is used to synchronize the timing
of all Ultra•Max systems located in a store,
shopping center, or mall. A reference system is
selected and then all other systems are
synchronized to the reference system.
The basic steps to synchronize all systems are as
follows:
A. Set up a reference transmitter at the
reference system.
B. Synchronize all other systems within the
range of the reference transmitter.
C. Use the second transmitter to extend the
range of the reference transmitter.
Repeat steps B and C until all systems in the
store, shopping center, or mall are
synchronized.
Before you begin, do the following:
•
Survey the site to identify the location and type
of EAS systems present. Systems that can not
be phased may need to be upgraded.
Upgrading of older equipment should be
planned in advance.
•
Locate all possible sources of 900 MHz
interference including cellular, cordless and
computer equipment. Where possible, avoid
using either the transmitter or the receiver in
those immediate areas. No interference has
been found with wireless equipment but the
presence of such equipment will reduce the
effective range of the Phasing tool.
•
Based on the proximity of the systems to be
phased, choose a starting reference system.
This is often the most difficult part. Choosing
the right reference system can minimize the
amount of phasing required.
Begin with steps A and B and then repeat steps C
and B until all systems are synchronized.
A. Setting up a reference transmitter
at the reference system.
1. Using the receiver, find the channel with
minimal interference.
Power on the receiver and rotate through the 8
available channels (position 0-7 only). Observe
the signal strength indicator and select the
channel with the lowest signal strength.
Note: Channels with steady or fluctuating high
levels of activity will not provide the maximum
range.

Phase all of the systems first! Don't spend a lot of
time tuning systems until all systems have been
phased.
Cover as much area as possible from a single
transmitter location. There will be some error build
up for each time a new transmitter is used.

2. Set up the transmitter.
a. Set the first transmitter to the same channel
as the receiver.
b. Locate a power outlet at or near the
reference system and plug in the first
transmitter.
CAUTION: Make sure the power select fuse on
both transmitters is set for the correct ac
voltage. To change the setting, use the
blade of a small scewdriver to pry out the
power select module. Rotate and insert the
module so that the correct voltage (115,
125, 230, 250) is opposite the arrow.
Locate the transmitter in a clear and open area
that will provide the best possible line of site
to all of the systems to be phased.
Note: Avoid locating the transmitter in the
ceiling or any metal enclosed areas.
c.
Set the switches of the transmitter to
Normal mode and ABC Signal.
3. Verify receiver operation.
a. On the receiver's signal strength indicator,
you should see a steady, strong signal.
b. Connect the output of the receiver to
channel 1 of an oscilloscope with the short
BNC cable and the sense coil to channel 2
with the long BNC cable.
c.
4. Align the reference transmitter
a. Beginning at the transmitter antenna of the
reference system, place the sense coil
against or near the transmitter coil. Position
the coil for the strongest possible signal.
Note: The sense coil is a cylindrical coil and is
very orientation specific. It must be in the
proper orientation for maximum sensitivity.

b. Verify that channel 2 shows the proper
transmitter burst signal.

While watching the receiver signal and
burst signal on the oscilloscope, adjust the
Phase Adjustment pot on the first
transmitter so that the burst signal starts at
the Falling Edge (beginning) of any one of
the three pulses. Use the “180° Flip” switch
if more adjustment range is needed.
Note: In general, you will want to make a
coarse adjustment with scope at a large
scale (e.g. 500µs or 1ms/division) and then
fine tune the adjustment with the scope at
50µs/division.
Note: Depending on the type of system being
adjusted, there will be some timing jitter in
the signals displayed. In this case, adjust
the transmitter such that the jitter is divided
equally between leading and lagging.

Tip: The transmitter can attract unwanted
attention when placed in a visible area of a mall.
Place a non-metallic item such as a plastic
caution cone over the transmitter to hide it from
view.
You are ready to begin phasing other systems
to the reference signal.
B. Synchronize systems within the
range of the reference transmitter.
1. At the next system, place the sense coil at
or near the transmitter antenna.
2. Verify that you are still receiving a clear
ABC signal from the receiver.
3. Align the system to the reference
transmitter.
While watching the receiver signal and the
system burst on the oscilloscope, adjust the
phase of the system so that the burst starts at
the Falling Edge (beginning) of any one of the
three pulses.
Note: In general, you will want to make a
coarse adjustment with scope at a large scale
(e.g. 500µs or 1ms/division) and then fine tune
the adjustment with the scope at 50µs/division.
4. Attach a sticker to the system indicating the
date that it was phased.
5. Continue phasing all of the systems within
range of the first transmitter signal.
C. Extend the range of the reference
transmitter.
1. Locate a power outlet within the range of
the first transmitter’s signal.
2. Using the receiver, find another channel
with minimal interference.
Power on the receiver and rotate through the 8
available channels (position 0-7 only). Observe
the signal strength indicator and select a
channel with low signal strength.

3. Set up the second transmitter.
a. Set the second transmitter to the same
channel as the receiver.
b. Switch the second transmitter’s signal OFF.
c.
Set the switches of the second transmitter
to Normal mode and ABC Signal.
4. Using the oscilloscope, align the second
transmitter.
a. Disconnect the sense coil from the BNC
cable.
b. Attach the BNC cable to the second
transmitter and channel 2 of the
oscilloscope.
c.
Switch the receiver back to the same
channel as the first transmitter.
Note: Channel 1 of the oscilloscope is attached
to the output of the receiver.
d. While watching the first and second
transmitters’ signals on the oscilloscope,
adjust the Phase Adjustment pot on the
second transmitter so that the second
transmitter’s signal starts at the Falling
Edge (beginning) of the first transmitter
pulse. Use the “180° Flip” switch if more
adjustment range is needed.
Note: In general, you will want to make a
coarse adjustment with scope at a large
scale (e.g. 500µs or 1ms/division) and then
fine tune the adjustment with the scope at
50µs/division.
5. Verify receiver operation.
a. Turn on the second transmitter’s signal.
b. Switch the receiver channel to the channel
used by the second transmitter and verify
that the receiver signal from the second
transmitter is aligned properly. You can
verify that it is aligned properly by
comparing it with systems phased
previously using the scope and sense coil.
Continue phasing systems as described in Step B.
No timing adjustment are required because of the
second transmitter.
Remove the first transmitter and use it as
necessary to extend beyond the range of the last
transmitter location and so on. Each time you
setup a new transmitter, you must realign the new
signal with the current reference signal as done in
step C.
OPERATING GUIDE
Phasing Team: If you have a team of CE’s with
several transmitters and receivers, you can
efficiently phase an entire mall using the following
approach:
Declarations
Regulatory Compliance
1. Start by identifying your reference system
and set up a transmitter at that site.
EMC: ................................ 47 CFR, Part 15
2. Using the receiver and an oscilloscope,
travel to the edge of the transmitted signal.
FCC COMPLIANCE: This equipment complies with Part
15 of the FCC rules for intentional radiators and Class A
digital devices when installed and used in accordance with the
instruction manual. Following these rules provides reasonable
protection against harmful interference from equipment
operated in a commercial area. This equipment should not be
installed in a residential area as it can radiate radio frequency
energy that could interfere with radio communications, a
situation the user would have to fix at their own expense.
3. Place and phase another transmitter where
the signal gets weak. Remember to use a
different channel for each transmitter.
4. Repeat this process until you have a large
area or the entire mall covered.
5. Once all the transmitters are set up, phase
all systems. When phasing a system, set
the receiver to the channel with the
strongest signal strength.
EQUIPMENT MODIFICATION CAUTION: Equipment
changes or modifications not expressly approved by
Sensormatic Electronics Corporation, the party responsible
for FCC compliance, could void the user's authority to operate
the equipment and could create a hazardous condition.
This technique allows CE’s to work independently
and multiple systems can be aligned at the same
time. An average-size mall can be phased in less
than a day.
