System Description

2.1.4 MASTER ALARM FACILITY
The MAF receives zone status (normal, alarm, fault) and transmits it (via a signalling
device) to the Brigade. It also operates the system alerting devices (e.g. electric bells) to
warn people to evacuate the building.
Individual (or blocks of) zones can be isolated, the Bells output can be isolated, but the
MAF (i.e. Brigade signalling) cannot be isolated.
In F3200 it is possible to have alarm zones which are not "mapped" to the MAF and/or
the Bells i.e. when in alarm, do not cause a Brigade signal or Bells operation.
2.1.5 ANCILLARY CONTROL FACILITY
The ancillary control facility consists of electric relays (electrically controlled switches)
which can be used to switch equipment which is not directly part of the Fire Alarm
System. Examples include shutting down airconditioning plant, returning lifts to a certain
floor and releasing fire stop doors held open by electric door holders.
2.1.6 NETWORKING
A fire panel may be part of a network of devices such as other fire panels, display and
control devices, and colour graphic displays.
This builds larger, more flexible systems, and also allows the display and control of the
system to be provided at multiple locations throughout a building or group of buildings. It
is possible that the brigade signalling would be done by only one panel on the network,
with the other panels transmitting alarm/fault, etc, to the common panel for signalling to
the brigade.
