To set the system, the user first enters his/her user code at a keypad or operates a
keyswitch connected to a Keyswitch zone. The control unit starts the exit tone (the exit
time is infinite for this mode). The user then operates the Final Exit zone and turns the key
in the lock switch to “locked”. The system sets seven seconds after the lock switch
contacts open.
While the lock switch is locked, the final exit zone operates as a Normal Alm zone.
To unset the system the user turns the lock switch to “unlocked” (closing the lock switch
contacts). The keypads start a continuous tone. At this point the user can lock the
lockswitch again without causing any alarm. When the user triggers the Final Exit zone,
the control unit starts the Entry Delay timer (page 57). The user completes entry by
unsetting the system in the normal way.
Note that when the user unlocks the lockswitch, the control unit cannot generate
confirmed alarms (page 77), since an authorised presence in the building is assumed.
The control unit can generate confirmed alarms if the user locks the lockswitch without
starting the Entry Delay timer.
Note: Use only one Lock Set zone per ward.
PSU Battery
A PSU Battery zone can connect to a monitored power supply, such as a 519, to monitor
the output voltage of the standby battery in the external power supply unit. If the zone
triggers, keypads sound a tone every minute and the panel generates a "PSU Battery"
alert message (displayed when a user enters a valid user code). Any outputs
programmed as type PSU - Battery (page 47 and 54) or Battery Fault (page 47) also
activate.
PSU Fuse
A PSU Fuse zone can connect to a monitored power supply unit such as a 519, which
can signal the condition of a fuse in the external power supply unit. If the zone triggers,
the keypad sounds a tone every minute and the panel generates a "PSU Fuse Blown"
alert message (displayed when a user enters a valid user code). Any outputs
programmed as type PSU - Fuse (page 47 and 54) also activate.
PSU Power
A PSU Power zone can connect to a monitored power supply unit such as a 519, which
can monitor the output voltage of the external power supply unit. If the zone triggers, the
keypad sounds a tone every minute and the panel generates a "PSU Power Supply" alert
message (displayed when a user enters a valid user code). Any outputs programmed as
type PSU - Power (page 47) or PSU Mains (page 54) also activate.
Masking
Masking indicates that a sensor is being obscured by boxes or other objects.
If a single three-resistor zone is used to communicate alarm, tamper and masking status,
use a standard zone type (e.g. Normal Alm), with the Masking attribute set (page 31). The
Installation Instructions describe how to connect such a sensor and the resistance values
needed to indicate each status.
Alternatively, two zones can be used: one for the masking status and the other for
alarm/tamper status. In this case, the sensor's masking contacts must connect to a zone
programmed as type "Masking", and the alarm/tamper contacts must connect to a
standard zone type. Double-pole (CCL) or FSL wiring can be used for either zone.
