FireSystemPro Smoke detector
Pro-SCD smoke ceiling detector
Pro-SCD is an optical smoke detector for duct mounting in all types of premises and reacts to visible smoke particles. It con-
sists of a detector head and a base, that comes with a bayonet mount to simplify service and maintenance.

Installation and wiring
Connect Pro-SCD to Pro-M master unit
Connect Pro-SCD to Pro-S damper unit
One smoke detector per Pro-S damper unit is allowed
Note:
Pro-M and Pro-S circuit cards have one 2.2 kΩ resis-
tors on each smoke detector connection.
When connecting a smoke detector to master/damper
unit, remove the resistor from the unit’s circuit card and
add it to the smoke detector.
The resistor is still required on the smoke detector,
see illustration to the right.
Move the resistor from Pro-M/Pro-S to Pro-SCD
