The SNM800 Sounder Notification Module is designed to provide an output, in response to a command signalled from a controller, to activate a number of polarised and suppressed sounders. The sounders are powered from an independent power supply and the module is capable of passing up to a maximum of 2 A (eg, 40 x 24 V dc 50 mA company sounders or a mixture of different current-rated sounders not exceeding a maximum current of 2A).

Features and benefits:

The PSM800 Power Supply Module (or equivalent) supplies the source power for SNM800 dc applications:

SNM800 can switch up to 2A
SNM800 supervises power supply
SNM800 monitors the wiring to signalling devices and will not switch on (even if commanded to do so), if a short circuit occurs. This prevents a single short circuit condition from disabling more than the output that contains the short-circuit.

The SNM800 may be used in conjunction with a RIM800 in an Extinguishing Configuration. An LED reports SNM800 status to the user. The LED lights when the SNM800 has been commanded to activate.
