Display Status Blanking
It may be a requirement that the Status (Set or Unset display) of the security system is
not displayed. If this option has been invoked by your installation company the Set or
Unset Status will only be displayed for ten seconds when the system is Set or Unset.
The top line of the display will then be blanked off.
You may check the Status of the system at any time by pressing the YES key and then
entering a valid User Code.
If the system was Set when you did this the display will ask if you wish Unset the
system. To do so press YES within ten seconds.
If the system was Unset when you did this the display will ask if you wish Set the
system. To do so press YES within ten seconds.
If you do not choose to Set or Unset the system within the ten seconds the top line of
the display will be blanked out and the code entry will be invalidated.
Keypad Alert
If programmed by your installation company, the two
PA
keys (or keys
1
&
3,
if
programmed by the engineer), when pressed together will act as alert keys. The exact
function will depend on what they have been programmed for. But for example, if they
are programmed as panic, pressing them will activate the alarm when the system is set
or unset.
Keypad Tamper
The keypad will monitor the number of attempts without a valid User Code being
entered. More than seven attempts will cause a keypad tamper and lock-out the
keypad for 90 seconds. This will be displayed as ‘LOCK-OUT Check’ and will require a
valid User Code entry to stop the sounders (only after 90 seconds). If the system was
Unset only the internal sounders will operate. If the system was Set a full alarm will be
generated.
System Tampers
The full security system is tampered, any attempt to remove covers from Keypads,
Control Panel, Keypads, Bell Box(es) or detectors will cause a tamper alarm. This also
applies to cut cables. If the system is Unset when the Tamper occurs the alarm will be
internal sounders only. If the system is Set a full alarm will be generated.
The alarm may be silenced by entering a valid User Code. The system may only be
Reset when the Tamper has been cleared, otherwise another Tamper alarm will be
generated.
