Nittan Evolution EV-SCM2 Sounder Control Module (Requires 24v PSU)

EV-SCM2 is a Dual Output Sounder Control Module, with PSU Fault Input and integral –ve line Short circuit isolator compatible with Evolution analogue addressable system devices. The Module includes a setting option to improve synchronisation of Sounder / Beacon products. LEDs are provided to Indicate Output active, Fault and Isolator Open.

The module is designed to fit the range of standard UK 2-Gang electrical enclosures, including Surface & Flush mount options. Device address may be set using EV-AD2-EXT Hand held programmer. The Short Circuit Isolator will protect the system, whilst allowing the device to continue communication from the opposite side. The isolator will self-reset when the fault clears.

The following resistors are required for Fault and Alarm monitoring:

EOL = 10k Ohm

All wiring must conform to the current edition of IEE Wiring regulations and BS5839 Part 1 All loop Cable Screens shall be connected together, but must be Isolated from Ground. Cable Screens shall be connected to Earth Ground within the Control Panel only.
