PSU Battery

A PSU Battery zone can connect to a monitored power supply 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 48 and 56) or Battery Fault (page 48) also activate.

PSU Fuse

A PSU Fuse zone can connect to a monitored power supply unit which uses relays to

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 48 and 56) also activate.

PSU Power

A PSU Power zone can connect to a monitored power supply unit 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 48) or PSU Mains (page 57) 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 29). 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.

Masking can activate mask outputs, depending on whether the zone is set or unset and

the Mask configuration options (see page 93). Also, masking may or may not inhibit users

from setting the affected ward, depending on whether the Mask Override or Mask Inhibit

configuration option is selected (page 93).

)

A masking zone, or a standard zone with a masking status, must remain active for

the duration of the Anti Mask timer (page 63) for a masking alert or masking

output to activate.

Occupancy

This zone type enables the control unit to display a warning message at the keypad if a

user sets a ward that may still be occupied by other people.

A zone of this type is normally connected to an "occupancy" output (open/closed contact)

of an access-control system. When the contact is opened, this indicates that the ward(s)
