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 designed to allow all the detectors in the same loop to
sound when one of the detectors goes into alarm.

smoke detector power-in terminals (brown to positive,
white to negative).

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 operation, distinct wiring methods are required. See
page 4 for specifics.

Installation
Choose a mounting location in the control panel within
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

reach of the provided wire leads. Use a water/isopropyl alcohol 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
When calculating total current draw of the control panel,
remember to add current consumption (29mA) for the
power reversal relay module (RR1).
WARNING
as noted below.
Testing
Wiring
1. Connect the relay module trigger wires to the fire alarm
output terminals.
Before testing, notify the proper authorities that the system
is undergoing maintenance and will temporarily be out of
service.
IMPORTANT: Polarity must be observed!
A. Continuous alarm/bell output: (Figures 1 and 2)
Connect red wire to positive and black wire to negative.
Test in accordance with NFPA 72 Chapter 7 test methods,
inspections, and testing frequency.
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-
1. To test the RR1 module, confirm that the smoke detectors 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.

Minimum Conditions Required for Proper Operation of the RR1 Upon Fire Alarm
For 2-Wire Model Smoke Detectors (Model 2100AT)
Auxiliary power supply for smoke detector sounders upon alarm and one of the following:
1. Bell, alarm, or programmable output exclusive to fire alarm. Output of minimum 30mA @ 9.5 Vdc required
–or–
2. Auxiliary power supply for RR1 and auxiliary relay with normally open contact activated by fire alarm only
For 4-Wire Model Smoke Detectors (Models 2112/24AT, 2112/24ATR, 2112/24AITR)
