AMBERAIR COMPACT S-CX v2023.3
4.16.2. FIRE AND FIREPLACE SAFETY (SAFETY INPUTS, DAMPERS)
Product AmberAir Compact can be equipped with fire dampers for extract and supply air.
Dampers are controlled by Spring-return actuators (A1, A2). Upon activation of signals EX2 DO1 and EX2 DO2 the dampers shall open. When
EX2 DO1/DO2 is deactivated, the dampers shall close. Fire dampers must be equipped with damper position switches. When the dampers
completely close, the switches K6/K8 should be activated. When the dampers are completely open, switches K5/K7 should be activated. MCB
controller can be configured to operate with NO or NC switches.
For fire safety function it is available to connect the external switch FA (i.e., smoke detector) to MCB DI4 input. By default, unit’s controller is con
-
figured to operate with NC fire safety switch. As long as the fire protection device is not connected to the ventilation unit, on an input there must
be a factory-installed jumper.
For the fireplace protection function, it is also possible to connect external fireplace protection switch FAA to MCB DI8 input. By default, the unit’s
controller is configured to operate with NO fireplace protection switch and it can be reconfigured.
