6 LaserSense HSSD-2 Aspirating Smoke Detector Installers Handbook
Stand-alone command module or command
module detector
When multiple detectors are networked together, a command module may be
used to tie all the detectors together and to provide a centralized point for
network access and programming, running diagnostics, and PC and fire panel
connection.
The command module can be mounted either inside a detector or as a stand-
alone unit in its own housing without an aspirator or smoke detection circuitry. If
detectors attached to the Command Module are mounted in different fire zones
then the Command Module must be mounted in its own housing with separate
power supply to comply with BS5839 and EN 54.
When a command module is mounted inside a detector, the Standard detector
display is replaced with a dedicated command module display. The programming
buttons and display on the front of the detector belong to the command module.
Programming at the command module is very similar to programming a detector,
the main difference being that the command module has extra functions to
control all the aspirating detectors connected in the network.
