5.22 RS232 Modem / Programming / Debug Interfacing
The modem I/O port is a DB9 connector ( CN8 situated on the lower left hand corner of the Main Board
BRD85MBA ) that is normally used for programming of the FACP via the serial port of a PC or Laptop. The
Controller also has the required hand shaking to support connection to a Modem, thus allowing the FACP
to be programmed from a remote site that has an established telephone connection. This allows the
system software to be upgraded by simply transmitting a file via the serial port of the PC or Modem
external to the FACP. Diagnostic facilities are also available via the same connection.

5.23 Ancillary
Services
The FACP has been designed such that detectors and/or call points, in addition to giving an alarm and
calling the fire brigade, will close or open circuits of ancillary services by means of relays or similar
devices.
Examples of these services are:
(a)
actuation of fixed fire-extinguishing systems;
(b)
closing of windows, smoke and fire doors,
(c)
control of ventilating systems;
(d)
covering of tanks containing flammable liquids and controlling their valves to isolate
the contents from direct contact with the fire, etc.
To facilitate safe maintenance of these services an option is available that allows for the isolation and
visual indication of the disablement of ancillary services that does not affect the normal operation of the fire
alarm system.
To ensure power to the fire alarm system is not prejudiced in any way, power for the ancillary services
must be included in the calculation of the power supply and battery capacity.
