4098-9772 Simplex 520HZ Sounder Base 4098-9772 Simplex Features TrueAlarm addressable sensor base with 520 Hz sounder
TrueAlarm sensor bases with 520 Hz tone require a TrueAlarm photoelectric, photo/heat, or heat sensor (ordered separately).
TrueAlarm sensor bases with 520 Hz tone are multi-point devices, use a single IDNet address, and receive communications and sensor power from the IDNet channel (the sounder base requires separate 24 VDC system power or NAC connection).
IDNet circuit allows the sounder to be supervised and coded by compatible NACs, allowing synchronized temporal, march time, or another channel coding.
Sensor and sounder operation is listed to UL Standard 268, UL Standard 464, and ULC Standard S529.
Sounder operation is also listed to UL Standard 464 as an audible notification appliance.

Base mounted address selection allows the address to remain with its programmed location when the sensor is removed for service or type change. Automatic sensor type identification provides default sensitivity when substituting sensor types.
