Note:
The keyswitch zone types are intended for use on zones that connect to an
access-control keypad, electronic key or other type of hardwired device used to
set or unset the system.
When the user operates the keyswitch while the system is unset, the control unit
starts the programmed exit mode.
When the user operates the keyswitch while the system is set, the control unit
unsets the system immediately.
The user cannot reset the system from a keyswitch zone.
Do not assign more than one Key Switch Latched zone to a partition.
Tamper – T (10)
Use this zone type to monitor the tamper status of external equipment. The control
unit monitors a Tamper zone at all times. When triggered in the unset condition, only
internal sounders operate. When triggered in the set condition, the alarm response
determines whether external sounders, strobe and communications also respond to
the alarm.
External PSU A/C Fail – PAC (11)
Use this zone type to monitor the A/C Fail output of an external power supply unit. If
a power supply unit triggers a zone with this type, the control unit treats this in a
similar way to a mains fail at the control unit itself. The action taken depends on the
values programmed into System Options – Mains Fail Delay (see page 75).
This zone type is not available for radio zones.
External PSU Batt Fault - PBF (12)
Use this zone type to monitor the Battery Fault output of an external power supply
unit. If an external PSU triggers a zone with this type, the control unit activates any
output of type Battery Fault and generates an “External Battery Fault” alert.
If the alarm system is set, the control unit logs the event, starts any programmed
communication, but does not start an alert until the system is unset.
This zone type is not available for radio zones.
External PSU Low Volts – PLV (13)
Use this zone type to monitor the Low Voltage output of an external power supply
unit. If a power supply triggers a zone with this type, the control unit activates any
output of type Low Volts and generates an “External Low Volts” alert.
If the alarm system is set, the control unit logs the event, starts any programmed
communication, but does not start an alert until the system is unset.
This zone type is not available for radio zones.
External PSU Fault – PF (14)
Use this zone type to monitor the fault output of an external PSU. (This zone type is
available for power supplies that do not provide specific fault outputs that can be
used by zone types 11, 12 and 13.) If a power supply triggers a zone with this type,
the control unit activates any output of type External PSU Fault and generates an
“External power fault” alert.
If the alarm system is set, the control unit logs the event, starts any programmed
communication, but does not start an alert until the system is unset.
This zone type is not available for radio zones.
