Operating instructions

2.8 System In Use
Whilst a keypad on the system is in use, all other keypads will display 'SYSTEM IN USE'
and will NOT respond to any keypresses (except for a Keypad PA alarm - see 2.9). This will
remain for 20 seconds after the last keypress, or until the display is returned to 'System
Ready.'
In the event of a 'Cannot Set' condition remaining after the normal exit time has expired, the
'System in use' message will clear, enabling any keypad to be used to abort the setting
procedure.
2.9 Keypad PA Alarm
Pressing the '1' and '7' keys simultaneously will generate an immediate personal attack alarm,
WHICH WILL SIGNAL TO THE ALARM RECEIVING CENTRE (if connected).
NOTE: this facility may not be available at all keypads.
2.10 Code Guessing Alarm
Eight consecutive attempts to enter incorrect codes on any of the system keypads will result in
a tamper alarm being generated.
2.11 Telecom Line Fault
If your system is connected to a Alarm Receiving Centre via a telephone line, an alarm tone
will be heard if a fault develops on the 'phone line whilst the system is unset. The tone may be
silenced by entering your code, after which the display will show:
Line Failure
Silenced!
If the YES key is pressed, the display will clear to the 'System Ready' prompt. If the fault
persists, or repeats, the display will show
Line Fault
CALL ENGINEER
The tone will not recommence until the system has been switched on and off again.
A Line fault at the time of switching the system on will NOT prevent the alarm from setting as
normal, but will override any programmed 'Bell Delay' as long as the fault persists.
2.12 Keyswitch Operation
If a keyswitch is fitted to your system, this may be used interchangeably with the keypad(s)
for setting and unsetting the system. It is NOT possible to omit zones, or select areas when
using the keyswitch.
If the system is set with the keyswitch and unset with a keypad, it will be necessary to return
the keyswitch to OFF before using it again to set the system. The position of the keyswitch
will NOT affect operation from the keypad(s).
NOTE: On a 2700 system, the keyswitch may be used to set the entire system (ie ABCD) or
'PART' on (ie areas A and B only). 2300 and 2500 Systems can switch to 'ABCD' on only.
The keyswitch will always switch off all parts of the system which are set.
2.13 Doorbell Facility
If a 'Push to Set' button is fitted to your system, this may be used as a doorbell..
Press the 'B' key whilst the display shows 'System Ready.' A '%' symbol will be displayed
towards the right hand end of the bottom line of the display. The system with then 'chime'
whilst the button is depressed. Pressing the 'B' key again will disable this function.
