Volume Control Override Relays

It is important that announcements and/or alarm signals come through at full volume, regardless of the volume settings of individual loudspeakers. The processor can be programmed to switch in a series of relays mounted on the Control Relay Card, which correspond to the loudspeaker zones selected. These in turn activate individual volume control override relays in the loudspeaker enclosures.

Using the Function Keys to Make a Call Using the four Function Keys (mounted on the Call Station) to make a call is done in the same way as using the Keypad.

The main difference being that instead of the operator selecting the zones using the Numeric Keypad, the Function Keys route the call to a pre-programmed selection of zones.

This of course saves a great amount of time when an operator has to frequently call the same selection of zones, or when an “ALL CALL” must be made in emergencies.

The Function Keys can also be used to select and broadcast an alarm or attention tone, or activate a pre-recorded message, without any microphone generated call being made.

Whenever the function key is pressed its Function Key LED illuminates, along with any Zone Selection Indicators activated by the routing of the Function Key. When the call is completed the LEDs are extinguished.

Microphone and Control Input Calls Calls, signals and/or pre-recorded messages, can also be activated by means of a microphone switch connected to the Microphone Input Module, and a remote switch wired to the Control Input Module (The last of course without a “live” call).

Power on delay

In order to conserve power for battery operated systems, the amplifier can be switched on only when a call is made.

It causes a time delay (programmable from

2-9 seconds) between pressing an activation key and the actual activation moment of the call. Relay 3 of the Control Relay Module is dedicated to switching the power to the amplifier(s).

Alarm interrupt

In order to conform with certain European military requirements an alarm call generated by a contact on a Control Input Module can be interrupted by a call with a higher priority. After releasing the relevant call key, the alarm signal will return for the programmed duration. Selection of the non- interrupted or interrupted mode is programmable in the “CTL ALARM MODE” program of the Installer Mode.

3ATTENTION AND ALARM SIGNALS

Built into the SM30 Control Centre is a signal generator, programmed with more than 40 attention tones and alarm signals. These can be programmed, via the User Menu, to proceed a call or pre-recorded message, or to be activated independently. As noted in the list below, some of these signals are terminated when the Call Station key, Control Input Relay, etc. is released. Other signals stop after about 1 minute, or when the Call Station activation key is pressed again. In order to confirm with STANAG (Standard Nato Agreement) requirements, an alarm signal can be interrupted by a call with higher priority. After releasing the call key, the alarm signal will return for the programmed duration. Along with the list below, chapter 6 (Call
