The smoke control damper may be equipped with a
230 V AC or a 24 V AC/DC actuator. See the per-
formance data on the rating plate.
The actuator must be connected according to the
wiring example shown. Several actuators can be
connected in parallel as long as the performance
specifications are taken into consideration.
Actuators with 24 V AC/DC
Safety transformers must be used. The connecting
cables are fitted with plugs. This ensures quick and
easy connection to the TROX AS-i bus system. For con-
nection to the terminals, shorten the connecting cable.
24 V actuators with AS-i module
The connecting cables of the AS-i module are fitted with
wire end ferrules.
Electric cables and system
For manual release (MA), the electric cables and
system must have at least 30 minutes circuit integrity.
For manual release (MA) we recommend using a
ceramic terminal to connect the AS-i cable to the
actuator cable or to the cable of the AS-i module.
Note:
Feeding the electric connecting cable through the
actuator encasing requires a drilled hole of the exact
size. A wire clamping bracket is required.
