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!

output terminals.

Connection Diagrams with Ademco Vista Panels

The connection diagrams enclosed show how to connect the 2100AT model smoke detector to the Vista panels using the
System Sensor power reversal relay module (RR2). Please make sure that the smoke detectors are connected properly to
the zones specified in the wiring diagrams for proper operation of the smoke detectors.

Figure 5. Connecting 2100AT smoke detectors to Ademco controls using RR2 module triggered from
bell/alarm circuit:

Programming information:

• The supervisory feature for the
bell circuit must be turned off.
See applicable control manual
for procedure.

RR2 Configuration:

•Set switch on RR2 to “OFF”.

Figure 6. Connecting 2100AT smoke detectors to Ademco controls using RR2 module triggered from
auxiliary relay:

Programming information:

• Program Auxiliary relay to
activate on alarms

• Assign Auxiliary relay as an
output for zones programmed
for fire alarm response only
(Types 9, 16, or 17)

RR2 Configuration:

• Set switch on RR2 to “ON”.

All smoke detectors on the 4-wire fire
zone will sound temporal 3 only from a
fire alarm event.
NOTE: • Program zone section attributes

for bell output to be pulsing.

• PGM2 must be programmed for
sensor reset.

• PGM1 must be programmed as
Burglary and Fire Bell Output (01)
with ON, ON, OFF attributes.

S0112-00

• RR2 switch must be set to OFF
(factory default setting).

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 test methods, inspections,
and testing frequency.

1. Confirm that all smoke detectors connected to the RR2
module(s) contain a sounder and the sounders are acti­vated upon power reversal.

2. Initiate an alarm with one of the smoke detectors con­nected to the RR2 module using any approved test
method. In the alarm state, all the detectors connected
to the RR2 module must be sounding their sounders.

3. Reset the system from the control panel. All smoke
detector sounders should be silent.

4. If the fire alarm panel also functions in burglary mode,
initiate a burglary alarm and ensure the smoke detectors
do not sound.
