Description

The standard system monitored PSU is the Folknoll standard Disabled Refuge EVC system power supply and standby battery unit. The unit is usually mounted on a wall in an equipment room near to one of the standard system controllers. The PSU unit is supplied fully enclosed and ready for wall mounting. The unit is convection cooled and should be mounted in a cool place with room for convection cooling to take place. A single standard system monitored PSU will provide power for a complete Folknoll standard Disabled Refuge EVC system of up to 20-off outstations. When fitted with a standard system battery set the PSU will provide power for 24 hours standby and 30 minutes operation in the event of a main supply failure. The unit enables the mains supply to be monitored by the Disabled Refuge EVC system. Mains failure is reported by the master station. The PSU unit has local mains fail alarm which can be silenced by means of a SILENCE button located on the outside of the enclosure.

Note

A single monitored PSU will provide power for a complete Disabled Refuge EVC system with up to 20-off outstations. The unit also houses  the battery set which provides standby power in the event of mains failure.
