General Description
The RR1 polarity reversing relay module is intended for
use with 2-wire and 4-wire detectors with built-in
sounder, such as System Sensor 2100AT, 2112/24ATR
and 2112/24AITR, and other compatible models. It is de-
signed to allow all the detectors in the same loop to
sound when one of the detectors goes into alarm.
NOTICE: This manual shall be left with the owner/user of
this equipment.
NOTE: If your panel configuration does not match any of
the provided wiring diagrams, please contact System Sen-
sor technical services at 1-800-SENSOR2 for assistance.
Installation
Choose a mounting location in the control panel within
reach of the provided wire leads. Use a water/isopropyl al-
cohol mixture (50/50) to clean the mounting surface. Allow
surface to dry and remove paper backing from the Velcro
and catch. Stick the Velcro in the panel and the catch on
the back of the module, then mount the module inside the
control panel. Route terminals to the appropriate terminals
as noted below.
Wiring
1. Connect the relay module trigger wires to the fire alarm
output terminals.
IMPORTANT: Polarity must be observed!
A. Continuous alarm/bell output: (Figures 1 and 2)
Connect red wire to positive and black wire to negative.
B. Alarm relay, normally open contact output: (Figures 3
and 4)
1) Connect one end of the alarm relay contact output
and the black wire to positive and negative of
power, respectively. Auxiliary power supply is used
as a power source for 2-wire detectors and power
to the detectors is used as a power source for 4-

wire detectors.
2) Connect the red wire to other end of alarm relay
contact output.
2. Connect the outgoing wires of the relay module to the
smoke detector power-in terminals (brown to positive,
white to negative).
3. Connect the blue and purple wires of the RR1 to any of
the power sources as specified in the applicable wiring
diagram (see Figures 1-4).
4. 2-wire models:
Connect the yellow and orange wires to the positive and
negative of the initiating loop, respectively.
4-wire models:
Connect the yellow and orange wires to the positive and
negative of power to detectors, respectively.
5. Connect the smoke detector initiating circuit to the
alarm loop.
WARNING
When calculating total current draw of the control panel,
remember to add current consumption (29mA) for the
power reversal relay module (RR1).
Testing
Before testing, notify the proper authorities that the system
is undergoing maintenance and will temporarily be out of
service.
Test in accordance with NFPA 72 Chapter 7 test methods,
inspections, and testing frequency.
1. To test the RR1 module, confirm that the smoke detec-
tors do not sound without an alarm.
2. Initiate an alarm with smoke or approved test method
on any detector connected to the control panel via the
RR1 module. In alarm, all the detectors that are installed
in the corresponding loop shall sound.
3. Reset the detectors by removing power to the loop.
NOTE: If using a power supervision relay, be
aware of the following: In an alarm condition, a
wiring-fault trouble state may also register at
the panel when the RR1 is used.
The RR1 cannot be used with a coded (or
pulsed) power supply. For proper RR1 opera-
tion, distinct wiring methods are required. See
page 4 for specifics.
