52 - Zones (cont’d)

09 Keyswitch

The Keyswitch function allows a zone to be used as an on/off switch for the system or assigned groups.

Operating a Keyswitch zone when the system is unset starts the timed full setting routine, therefore the exit

time is applicable. The system sets when the exit time expires or a Final or Push Set is activated.

If the system is set, operating a Keyswitch immediately unsets the assigned groups; there is no entry time

countdown.

The Keyswitch operation is as follows: 1kΩ to 2kΩ sets the system; 2kΩ to 1kΩ unsets the system.

NOTE: The activated zones are not displayed on the keypad when a Keyswitch is used to reset the alarm.

Keyswitch operation with groups enabled

When groups are enabled, a keyswitch zone will set and unset only the group that it is programmed to.

However, if the keyswitch is programmed to the common group (group four), then it will set and unset

the groups in the common group map (see Option 63.1.2).

13 PA

The PA (Personal Attack) function is continuously operational. Activation of this zone type overrides the Bell

Delay parameter and causes an instant full alarm condition that requires to be reset with an authorised user

code.

14 PA Silent

The PA Silent function is identical to the PA function, with the exception that there is no audible or visual

indication of the activation; that is, no bells or strobes are activated. Only the PA output (normally channel 2

on the digital communicator) signals the alarm. The activation (+) and restoral (–) of PA Silent zones is

recorded in the event log.

17 Link

This has no alarm function but can be used to activate links.

18 Spare

The Spare function allows any zones that are not being used to be ignored by the system; the resistance

readings from the circuit - including the tamper conditions - do not activate an alarm condition.

NOTE: It is recommended that all unused zones are programmed as Spare and that a 1kΩ 1% resistor is

connected across each of these zones.

19 Fire

The Fire function is continuously operational. When activated, a FIRE zone overrides the Bell Delay pa-

rameter and activates an instant alarm (Bell, Strobe and Fire). The keypad buzzer and control panel horn

output, if fitted, emit an interrupted tone (one second on, 0.5 seconds OFF), easily distinguishable from all

other alarm conditions. Any valid code entry cancels the Fire activation.
