General Description

The RR2 polarity reversing relay module is intended for
use with 2-wire and 4-wire detectors with built-in sounder,
such as System Sensor 2100AT, 2112/24AT, 2112/24ATR
and 2112/24AITR, 501BH, 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.

The RR2 may be used with an alarm zone that provides
coded output for fire and continuous output for burglary.
By default the RR2 will only trigger when the alarm output
is coded. In this manner, smoke detectors will only sound
from the result of a fire, and not from a burglary alarm.
When the RR2 is used in this mode, the smoke detectors
must provide for coded alarm signals if required by the
specification.

The RR2 can also be set to only trigger on continuous
alarm zone signals. When used in this mode, it will not
trigger from a coded fire alarm signal.

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 Sensor
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
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 as noted below.

When calculating total current draw of the control panel,
remember to add current consumption (25mA) for the
power reversal relay module (RR2).
IMPORTANT: If the fire alarm output signal is coded, set
the switch on the RR2 to “OFF”. If the fire alarm output
signal is continuous, set the switch to “ON”.

Wiring

IMPORTANT: All polarities must be observed!

1. Connect the RR2 module trigger wire to the fire alarm
output terminals.
A. Alarm/Bell output: (Figures 1 and 2)
Connect the purple wire to the Alarm or Bell output.
B. Alarm relay, normally open contact: (Figures 3 and 4)

1. Connect one end of the alarm relay contact output

2. Connect the purple wire to the other end of the

2. Connect the red and black wires to the panel auxiliary
or detector power (red to positive, black to negative).

3. 2-wire models

Connect the yellow and orange wires to the panel initiat-

ing circuit (yellow to positive, orange to negative).

4-wire models
Connect the yellow and orange wires to the panel detec-

tor power circuit (yellow to positive, orange to nega­tive).

4. 2-wire models

Connect the brown and white wires to the smoke detector

initiating circuit (brown to positive, white to negative).

4-wire models
Connect the brown and white wires to the smoke detec-

tor power circuit (brown to positive, white to negative).

NOTE: In an alarm condition, a wiring-fault
trouble state may also register at the panel
when the RR2 is used.
