Split System Operation
Most users will have experience of a conventional intruder alarm system sometimes referred to as
a Single Area System which is either Set or Unset. The RS125 Split System allows up to four
separate Guard Groups (or Areas) to be Set and Unset independently; the Access Codes can be
set up with Area Authorisation Tags to restrict some users to pre-determined Areas; this affects
the operation in several respects which are detailed below:-
The System Manager will need to specify which areas are accessible to each User.
You can Part Set and Part Unset the system on a selective basis. The status displays on the
Remote Keypad show which areas are Set and Unset.
There will be Set Areas while the premises are still occupied; there is a significant False Alarm
hazard from users accidentally entering a Protected Area during the day. The system is only
Fully Set when all Areas are Set; this means that the operation of the Exit/Entry systems may
be different when the User is last to Set or first to Unset.
If a Remote Keypad is being used and a Set Area switches to Entry Mode, the Entry Mode will
take priority and all the Remote Keypads will show “Enter Code”. The current user may need
to wait after entering his own Access Code because control may need to pass to another
Remote Keypad.
There may be a Final Exit Area which provides a common access route to several Internal
Areas; these Internal Areas must all be closed before the Final Exit Area can be closed.
The last person to leave the premises may be unable to close the Final Exit Area because
another User (with a different Access Code and Area Authorisation) has failed to set an
Internal Area.
There is only one Audible Warning system common to all Areas.
A Split System with up to four separate Areas would be used in a typical commercial installation
with more than 10 Users and at least 16 detection zones.
Part and Full Set
If you use the [PART] key during setting/unsetting, the system will ask a series of questions to
ascertain which Areas you wish to Set or Unset taking into account the current Set Status of the
different Areas and your Area Authorisation.
If you use the [FULL] key during setting/unsetting, the system will assume that you want to
set/unset all Areas for which you are authorised and it will proceed accordingly. If the Entry
Timer is running, the system will unset all Areas which are covered by your Area Authorisation.
If you are unsetting from a Part Set situation you will be asked whether a Set or Unset operation
is required.
Exit Termination
If you are setting new Area(s) the system will go into Exit Mode as part of the setting procedure
for the newly selected Area(s). If the system being closed does not introduce a new Final Exit it
will use a Time Setting mode which requires no Exit Termination.
Alarm Activations
To silence an alarm enter your Access Code; the system will display a series of
messages giving details of the alarm events which occurred since the last time an
Access Code was used. You may need to call your Alarm Company or Alarm
Receiving Centre immediately.
