DSI Group Control Panel (GCP)

Smoke and Fire Curtain option

Function
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.

Testing
Key switch control on panel.

Status Indication
LED series on panel: Green=main power healthy, Red=fire status, Bottom Green=battery failure.

Compatibility
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.

Options
Optional modules for delayed descent, split drop, and BMS relays are available as an upgrade.

OPERATION IN CASE OF FIRE OR LOSS OF POWER

  • 1. Electrician to supply and run 3- solid 14 gauge color coated wires (14-3) for low voltage loop.
  • 2. Electrician to supply and mount 2- double gang “J” boxes at each smoke curtain and at GCP.
  • 3. “J” boxes must be clearly labeled “in” for incoming from GCP and “out” fore wire going out to the next smoke curtain or back to GCP.
  • 4. See MCC electrical requirements for further details on the location of “J” boxes.
  • 5. The maximum allowable length of the entire 24 volt loop from GCP to all mcc’s and back is 250 feet.
  • 6. Allow at least 6 feet of extra wire inside each “J” box in order for door systems to make final connections. There shall be no splices in wire loop.
  • 7. “In” and “out” wire must be run in separated conduit.
  • 8. All “J” boxes must be clearly labeled.
