The GCP provides power to the MCC units when the fire alarm status is normal (closed). If the fire alarm is activated, the MCC units are powered down allowing the curtains to deploy via gravity to their operational fire position. When the alarm is reinstated, the MCC’s are powered up retracting the curtains. If there is a main power failure, the back-up batteries provide power to the MCC’s for up to 3 hours (subject to load) and prevent deployment until discharged, unless overridden by an alarm signal. Delayed descent and delayed reset functions are fitted as standard.
Integral Battery Back up
Up to 3 hour power supplied by two 7Ah rechargeable sealed lead acid cells.
Key switch control on panel.
LED series on panel: Green=main power healthy, Red=fire status, Bottom Green=battery failure.
The GCP runs up to 5 MCC unites (5 motors) from the 24v ring output. Two stage descent (with brake motors) is fitted as standard and is adjustable to suit project requirements.
Optional modules for delayed descent, split drop, and BMS relays are available as an upgrade.
