INTERCONNECTING MULTIPLE SMOKE ALARMS
Interconnected units can provide earlier warning of fire than
On Intiating Alarms | Red LED(s) flashes(flash) rapidly |
On All Other Alarms | Red LED is Off |
All wiring must conform to all local electrical codes and Article 760 of NFPA 70 (NEC). Refer to NFPA 72, NFPA 101, and/or your local building code for further connection requirements.
AC and AC/DC Smoke Alarms can be intercon- nected. Under AC power, all units will alarm when one senses smoke. When power is interrupted, only the AC/DC units in the series will continue to send and receive signals. AC powered Smoke Alarms will not operate.
Interconnect units within a single family residence only. Otherwise all households will experience unwanted alarms when you test any unit in the series.
Interconnected units will only work if they are wired to compatible units and all requirements are met. This unit is designed to be compatible with:
BRK Electronics® Smoke Alarm Models 100S, 2002RAC, 4120, 4120B, 4120SB, 4919, 5919, 5919TH, RM3 (Relay Module); BRK Electronics® Heat Alarm Model HD6135F; and First Alert® Smoke Alarm Models SA4120B, SA4121B, SA4919B, SA86B, SA100B.
Interconnected units must meet ALL of the following requirements:
•A maximum of 18 compatible units may be interconnected (Maximum of 12 smoke alarms).
•The same fuse or circuit breaker must power all interconnected units.
•The total length of wire interconnecting the units should be less than 1000 feet (300 meters). The interconnect wire should be #18 gauge or larger, rated at least 300V.
•If an interconnect wire is not already part of your household wiring, you will need to install one. This type of wire is commonly available at Hardware and Electrical Supply stores.
Failure to meet any of the above requirements could damage the units and cause them to malfunction, removing your protection.
