removal to trigger). After an alarm the pins will return to their quiescent state
(+12V) when the user resets the system.
Keypad Panic Alarm
The Installer can program the panel so that users can start a Panic Alarm by
pressing keys 1 and 3 at the same time on any keypad. The Panic Alarm
works whether the system is set or unset. When the panel is supplied from the
factory this feature is disabled.
Chime
The internal sounders can give a chime tone when selected detectors are
activated while the system is unset. The Installer selects the zones during
programming. The user can turn the facility on or off.
Power Supply
To comply with BS4737, the control panel's mains supply should come from
an un-switched, fused spur unit fitted with a 1A fuse. All electrical connections
should be carried out by a qualified electrician and must comply with the
current IEEE Wiring Regulations: 16 Edition, Appendix 5 - Standard Circuit
Arrangement. The control panel must be fitted with a rechargeable stand-by
battery so that the system can continue to operate during a mains power
failure.
User Control
The panel provides two independent 4-digit user access codes (defaults 1234
and 0000). The user can change either of these codes at any time, but
cannot program the system with these codes. Note that the default second
user code (0000) is inactive.
The user can set the panel in the following modes:
Full Set
All the zones function as programmed during installation.
Part Set
Selected zones are omitted. The Installer must program which
zones will be omitted.
Set with Omit
One or more zones temporarily omitted. The user selects the
zones to be omitted during setting. Note that the user cannot
omit zone 6 if it is programmed as a Panic Alarm, zone 5 if it
is programmed as a Fire zone, or any Entry/Exit zone.
Log
The panel keeps a record of the last 10 alarm and tamper events. The Installer
can read the log in programming mode by using command 90 (see "4. Pro-
gramming"). The system displays events by lighting the appropriate LEDs on
the keypads. To see earlier events press << (1), for later events press >> (3).
