UL Installations For UL installations, the total current drawn from this output and the auxiliary

power output, combined, cannot exceed 700 mA. In addition, the sounding

device must be a UL Listed audible signal appliance rated to operate in a 10.2-

13.8 VDC voltage range, and must be mounted indoors. Example: Wheelock

Signals Inc. siren model 34T-12 (provides 85dB[A] for NFPA 74 & Standard 985).

Non-UL Installations The total current drawn from this output cannot exceed 2.8 amps. A battery must

be installed since this current is supplied by the battery. Up to two 702 sirens can

be used, wired in series. Up to two 719 sirens can be used, wired in parallel.

IMPORTANT: Going beyond the limits indicated above will overload the power

supply or may possibly trip the bell output thermal circuit breaker.

PABX

Important!

If the communicator is connected to a telephone line inside a PABX,

be sure the PABX has a back-up power supply that can support the PABX for 24

hours. Many PABXS are not power backed up and connection internally to such a

PABX will result in a communication failure if power is lost.
