The Nittan EV-SCM Sounder Control 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 2A.
Use an EN54 approved PSU, to supply the source power for EV-SCM dc applications:
- EV-SCM can switch up to 2A
- EV-SCM supervises power supply.
- EV-SCM 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.
24V Input Power Voltage Requirement:
26.4V Max., 21.9V min. This allows for 0.9V
max. voltage drop between a suitable power
supply and the EV-SCM.
An LED reports EV-SCM status to the user.
The LED lights when the EV-SCM has been commanded
to activate.
