If the central unit is attached on top of the I/O unit, also the metallic spacer plate must be attached
with these screws. When you are attaching the central unit directly to the wall, the space plate is
attached to the wall by drilling. The central unit is secured at the bottom with two screws.
For more information about electrical connections, see the separate user and installation guide.
Servicing and alarms
The Halton Safe control centre (HSM) and Halton Safe Link (HSL) control unit do not need any
special servicing.
The Calectro smoke detectors for duct or ceiling installation issue the following alarms:
•
Service
= This situation occurs when the detector’s contamination passes
a certain threshold. The alarm does not close the fire dampers.
•
Alarm
= This closes those fire dampers in the smoke detector’s use group.
•
Short Cut
= This means that there is a short circuit in the smoke detector’s
cable. This causes the fire dampers in the smoke detector’s use group to close.
•
Broken line
= This means that the cable to the smoke detector is broken.
The fire dampers in the relevant smoke detector’s use group are closed.
The smoke detectors are cleaned according to instructions provided by Calectro.
