PM4/8/12/16 & PM4/8-SA Installation and User Guide v1.0

7. Release the GROUP button.

Note that once a chime is assigned to a group, it is not possible to check which chime

it is, as pressing a GROUP button will illuminate the zone and message LEDs, but

gives no indication corresponding to the chime.

Note also that if a chime number is assigned for which no chime le exists, the group

will operate normally, though there may be a slight delay before a message starts.

Setup options

The PM has a number of setup options which can be congured during installation.

These modify the operation of the unit in various ways, allowing the PM to be

optimised for the particular installation. Most of these options are set by moving

internal PCB jumpers. See “PCB layout diagrams” on page 49 for a PCB layout

diagram identifying the location of all the jumpers. See ”Accessing the internal PCB”

on page 20 for instructions on how to gain access to the internal PCBs.

NOTE: Jumper settings are only checked by the PM’s processor on power-up.

In order for jumper changes to be recognised, power to the PM will need to be

disconnected and then reconnected.

When removing jumpers it is recommended that the link remains connected to one

leg of the header, to prevent losing it.

Mic Level

Mic volume may be adjusted with the preset control PR2 on the main PCB. See “PCB

layout diagrams” on page 49 for the location of this control. It is recommended

that, if possible, the operator who will normally make announcements from the PM

makes test calls to assess the system volume when adjusting mic level. Note that the

microphone will be ‘off’ if PR2 is turned fully anticlockwise.

Zone Offsets

By default, a zone button on a PM selects paging (and messaging on SA models) to the

same-numbered zone. Thus the buttons on a PM4 (or PM4-SA) will normally address

Zones 1 to 4, and those on a PM8 (or PM8-SA) Zones 1 to 8. However, there may be

situations where a PM is required to address a different subset of available zones to

the set starting at Zone 1.

It is possible to “shift” the zones a microphone addresses by any value between 1 and

15 by setting a numerical offset. With an offset applied, the zone a button addresses

will be that button’s ‘default’ zone number PLUS the offset value. Example: the four

buttons on a PM4 (or PM4-SA) can be made to address Zones 10 to 13 by applying

an offset of 9.
