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
B. Synchronize all other systems within the

Operating Guide
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.

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.

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.
If you have a team of CE’s with several phasing
tools, you can efficiently phase an entire mall. See

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.
Avoid locating the transmitter in the

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. Verify that channel 1 shows the proper ABC
signal from the transmitter. (One wide,
3ms, negative going pulse followed by two
narrow, 1ms, negative going pulses with a
separation of 5.556ms for 60Hz and
6.667ms for 50Hz.) Best viewed at
1ms/division.
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.
The sense coil is a cylindrical coil and is
Note:
very orientation specific. It must be in the
proper orientation for maximum sensitivity.
b. Verify that channel 2 shows the proper
transmitter burst signal.
In general, the reference system should

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:
1. Start by identifying your reference system
and set up a transmitter at that site.
Declarations

Regulatory Compliance
Regulatory Compliance
Regulatory ComplianceRegulatory Compliance
EMC: ................................47 CFR, Part 15
2. Using the receiver and an oscilloscope,
travel to the edge of the transmitted signal.
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.
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.
FCC COMPLIANCE:
15 of the FCC rules for intentional radiators and Class A
digital devices when in stalled 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 rad io communications, a
situation the user would have to fix at their own expense.
EQUIPMENT MODIFICATION CAUTION:
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.
