The control panels available in the market range from
small compact type which incorporates a hooter / siren and can accommodate a few different
types of Sensors (12) (detectors) to a more advanced type which can
perform more complex functions like, automatic dialing to a phone / pager / cellular phone
and convey a pre-recorded message informing about intrusion, in addition to or in place
of, local audio visual alarm.
The advance versions also have the capability of functioning with user codes for arming
and disarming and of switching over to built-in power supply in case of power failure.
Many control units also use a remote (infra-red or Radio Frequency based) for arming or
disarming of the control unit.
For larger installations that have more than 3-4 sensors, there is provision of Zones (30). Each Zone is associated with one or more sensors e.g. one
floor could be controlled by one Zone, the Fire Sensors could be connected to another
zone. The advantage of Different types of Zones(31) is that when
the alarm goes off (alarm sounds), the control panel gives an indication as to which Zone
has been compromised. This way one has to only check the sensors linked to that particular
zone to see where the problem is.
Please note that many times the sensor, control unit & alarms unit may be combined in
a single housing for reducing cost or to provide easy localized, protection. However,
larger systems involving multiple sensors will invariably have a separate control unit.
