Microphone Input module should be started with contact 1-8 of the Control Input Module. See user programming 14.3 menu item 3.8 ‘Control inputs 1-8’.

Relays 3-12

Relays 3 (or 4 if power-on delay is used) to 12 can be activated by different sources, and may be used for a number of functions.

Remote Volume Control Overrides

The ‘make’ contacts of Relays 3 to 12 may be used to activate up to 10 loudspeaker volume control override relays. These relays, mounted in the loudspeaker enclosures, override the volume control setting of the actual loudspeaker itself. This means that regardless of the individual ‘music’ volume setting of each loudspeaker, all the loudspeakers in a particular zone will work at full volume when a Call is routed to it.

13.2Installation

Mounting in the Control Centre One Control Relay Module is used in SM30. This must be located in Control Centre slot J, as indicated in fig.5.1.

Wiring Control Relays

Each Control Relay Module is supplied with two plug-in, 16 terminal, screw connector blocks (fig.13). The wires to remote equipment are connected to the screw terminals, which are marked in threes 1 to 8 (make and break contacts), and in pairs 9 to 12 (make contact). The great advantage of the connector block is that if, for some reason, the SM30 Control Centre has to be removed, the blocks have simply to be unplugged and the wires remain intact. This avoids the tedious and risky business of rewiring the blocks in their original configurations.

13.3Programming

Power-on delay

The Power-on delay function can be programmed with a time delay of 2-9 seconds (see installer programming 14.7 menu 5 ‘Power-on delay’).

Coupling relays to zones

Each Control Relay is programmable, ‘linked’ or ‘locked’, to a specific Zone Relay, so that when a call is routed to a loudspeak- er zone, the Control Relay linked to it will activate automatically (see installer program- ming 14.7 menu 11 ‘Override relays’). The display will show ‘Z’ for the relays involved.

Activation by Call Station and Function Keys

Relays 3 (or 4, if power on delay is used) to 12 may be programmed to be activated by Call Stations, and Function Keys on Call Stations. Activation by a Call Station happens whenever a call is made using Keypad of the Call Station Keypad (see user programming 14.3 menu 1.7). Activation by a Function Key happens whenever a pre- programmed Function Key (followed by the ‘Press-To-Talk’ key) is pressed (see user programming 14.3 menu 1.14).

Activation by Control Inputs

Relays 3 (or 4, if power on delay is used) to 12 may also be programmed to be activated by Control Input contacts (see user programming 14.3 menu 3.12). Control Input contacts 5 to 8 can be programmed to activate one, or a group of, Control Relay(s). This means that when the remote switch of a control input is closed, the programmed Control Relays become activated (see user programming 14.3 menu 3.7).

The display will show ‘A’ for the relays involved.
