WHITECOTES CIRCUIT FAILURE MONITORING UNIT

WHITECOTES Circuit Failure Monitoring Unit - The basic use of a switched maintained system is to energise the emergency lighting when required. By operation of the local switched supply it automatically illuminates in the event of local sub-circuit supply failure (irrespective of the position of the local switch). WHITECOTES Circuit Failure Monitoring Unit changeover relays are compact and easy to install. When using changeover relays, switched maintained emergency luminaires are energised whenever a local switched supply is present and, automatically, when a local sub-circuit failure occurs.

• Static inverter changeover module
• Suitable for 50V, 110V or 230V AC or DC systems
• In the event of local sub-circuit supply failure the local emergency lighting circuit is energised (irrespective of the position of the local switch)
• Compact and easy to install
• Supplied either as a changeover module, which can be integrally mounted within the luminaire, or housed in a fire rated
• enclosure for remote mounting
• Emergency lighting changeover relays with an additional dimming inhibition relay that will restore a fitting that was running in a mains dimmed state, to full brightness for emergency operation
• Compatible with fluorescent and LED loads
• The associated control gear must be capable of being run from the emergency voltage
