Sounders
Sounders are used as internal warning devices, to indicate a range of events that have, or are taking
place. (See sounder tones earlier in this chapter).
Bells
This is an external warning device, (this could also include a siren), to inform the neighbourhood that
an event has occurred and help may be required. (See also Alarm times earlier in this chapter).
Strobes
Strobes (flashing lights) are used to give a visual indication for quick identification of the location of an
alarm, very useful in shopping centres etc..
Communicators
A device used to communicate between the alarmed premises and a remote location such as a central
station. Communicator can take the form of digital communicators, which dial to the central station
and pass the relevant alarm information. Red Care systems that are continually monitored and change
the signal conditions to signal alarm states to the central station. VODASSURE an AB-NET
communicator signalling the alarm conditions over the PAKNET radio data network to a central
station. The central stations are manned 24 hours a day 365 days a year, on receipt of an alarm,
evaluate the messages received and call out the appropriate services. (I.e. The keyholder, Police or Fire
Services).
System Configuration
The system is built up of a number of zones, these zones may have been split into two circuits to aid
recognition and fault finding. The zones/circuits may then be arranged to work in specific areas such
as in a factory, to enable the office, workshops and stores to be controlled separately.
Area 1, 2 and 3
The Abacus panels can operate with up to 3 areas plus a common and cleaner area (See System
Features for your panel). This allows the system to have individual areas set from specific area codes.
If
the installation engineer have set the panel to mode 2 (version 5000 or later), then the main or
master codes can set/unset a specific area.
Whenever areas are used, an individual code must be
available for each area.
Common Area
A zone programmed as common, is common to all areas, therefore is set when the last area is set, and is
unset when the first area is unset (i.e. The common area is unset when any one or more areas are unset).
Cleaner Area
In some locations, an individual may require to unset zones in several areas. (I.e. a Cleaner or
Security Guard is required to unset all the corridors but not the offices). This function can be
undertaken by a cleaner code, when entered in the unset mode only displays ‘Cleaner on Site’ but when
set, Unsets all zones programmed as cleaner, on re-enter of cleaner code, Sets all zones programmed
as cleaner. Other codes can override this function (i.e. An area code when used to set an area, is
requested ‘Cleaner on site ok?’ – if replied NO then panel sets all zones in that area, if replied YES
then panel sets those zones not programmed as cleaner in that area). (See System Features).
Part Set
Zones in each area can be programmed as part, which on part setting the area or installation will be
omitted. An example of this is the bedrooms, at night you can part set the installation and go to the
bedroom without the bedroom detector causing an alarm.
