PM4/8/12/16 & PM4/8-SA Installation and User Guide v1.1

Conguring the PM

Zone Groups

Zones may be ‘grouped’ together to simplify the procedure for paging several zones

simultaneously. Up to four groups (A to D) may be dened on PM models PM4, PM8,

PM12, PM16 and PM4-SA, and up to eight groups (A to H) on model PM-8SA.

Using groups simplies operation for the user; when a GROUP button is pressed,

the LEDs corresponding to the zones comprising the group illuminate, to give

conrmation of which zones are to be addressed. Pressing the TALK (or TALK/SEND)

button then activates the PM for all the zones simultaneously.

The SA models of the PM have extra functions allowing specic messages and chimes

to also be assigned to zone groups. This gives much greater exibility in operation, and

allows external triggering of pre-recorded messages to pre-determined zones.

Once zone groups have been dened, it is possible to ‘lock’ the denitions, so that

they cannot be inadvertently altered by users. See “Lock Groups” on page 37 for

details of this option.

NOTE: - if any zone access is to be restricted by using the PM’s Zone Disabling

feature, it is recommended that this is done before dening any zone groups (as the

NVM reset which forms part of the button disable procedure will cancel any zone

groups). See “Disabling Zone buttons” on page 41 for details of how to disable

Zone buttons.

Dening a zone group – groups A to D (all models)

1. Select the zones for the group with the ZONE buttons; the selection will be

conrmed by the adjacent LEDs. (An incorrect selection may be cancelled with

the CLEAR button.)

2. Press and hold down one of the GROUP buttons until the zone LEDs ash

(approx. 5 s).

3. Release the GROUP button.

Dening a zone group – groups E to H (Model PM-8SA only)

1. Select the zones for the group with the ZONE buttons; the selection will be

conrmed by the adjacent LEDs. (An incorrect selection may be cancelled with

the CLEAR button.)

2. ‘Double-click’ and hold down one of the GROUP buttons (approx. 5 s) until the

zone LEDs ash.

3. Release the GROUP button.
