Fully Addressable - D.I.D. Interface Details

D.I.D. (Damper Interface Device)

The DID consists of a pcb mounted Hochiki CHQ-POM device fitted within a wall mounted enclosure. The enclosure is provided with the relevant number of glands to accept the control site wiring of data loops, power supply (by others) and actuator flying leads.

The DID will control and monitor the combination Fire and Smoke Dampers or Smoke Control Dampers thus providing the correct operation to the advised cause and effect and reporting the status of the damper.

The DID is normally supplied separately for positioning within 1 metre from the damper actuator to allow direct connections of the actuator flying leads and site wiring by others.

The Damper Interface Device is powered from the data loop with a local supply (by others) being switched through the DID relay to control the damper operation.

Damper interface as described opposite with an additional Potentiometer mounted on the enclosure to provide for 0–10 volt mid position control. Alternatively, this device can be offered without the potentiometer but ready for an external 0-10 volt signal for mid position control by others.

The device allows for control of the modulating actuator to achieve three positions as follows:
•  Fully open
•  Fully closed
•  Mid position 0° - 90° open - fail safe closed in alarm condition

The enclosure dimension is 170mm x 120mm x 60mm
