Read and follow all instructions supplied with each Alarm and the RM3 Relay before installing and  
using the relay. Do not attempt to connect any auxiliary devices without using the RM3 Relay. Use  
the RM3 Relay only with compatible BRK Electronics, Inc. and First Alert Alarms.  
The RM3 Relay will not operate auxiliary devices without 120V AC power. The Smoke and Heat  
Alarms provide the interconnect signal to trigger the RM3 Relay they do not supply any power to  
drive the auxiliary device.  
AC Alarms and AC Alarms with battery backup can be interconnected. Under 120 V AC power all units  
will respond if at least one Smoke or Heat Alarm sounds. When AC power is interrupted, only the inter-  
connected Alarms with battery backup will be capable of initiating an audible Alarm. Alarms with AC  
power only will not operate.  
NFPA guidelines allow a maximum of 18 compatible First Alert and BRK Electronics, Inc. Smoke  
Alarms, Heat Alarms and RM3 Relays to be interconnected. No more than 12 of the 18 devices  
shall be Smoke Alarms.  
The RM3 Relay should not be used to connect groups of alarms with a fire alarm control panel or  
to interconnect chains of alarms to each other since there will be no way of knowing which detec-  
tor caused the alarm.  
Residential Smoke and Heat Alarms do not latch. If alarm levels of smoke or heat subside, the  
operation of the audible alarm signal and the auxiliary device connected to the RM3 will automati-  
cally cease.  
The RM3 Relay should only be installed where conditions normally remain between 40º F to 100º F  
and 10% to 90% relative humidity.  
Alarm and relay installation must conform to the electrical codes in your area and Article 760 of the  
U.S. National Electrical Code. Wiring should be performed only by a licensed electrician. This relay  
should be used only in a covered junction box with sufficient volume for proper installation. The  
circuit used to power the alarm and relay must be a 24-hour 120V AC pure sine wave, 60Hz circuit  
that is not controlled by a switch or a dimmer.
