6.2Installation

Loudspeaker Zone Template

A paper template is provided, on which the names of the loudspeaker zones can be written. The template has a detachable blank section at the bottom, allowing it to be used in a typewriter.

To mount the template in the Call Station, first remove the right hand side cheek (fig.6.1D), by unscrewing the two screws in its side (fig.6.1E), and the one screw located in the bottom. The plastic template cover (fig.6.1C) can now be slid out. Place the (type) written template in position over the zone LEDs (having first torn off its blank perforated panel), and carefully slide the plastic template cover back in place.

Connection to Control Centre Between the Call Station and the Call Station Input Module (see chapter 7.1) the following cabling is needed::

■a shielded twisted pair for audio and power transport;

■a twisted pair for data transport. When the copper diameter of each wire is not less than 0.75 mm2 the length of the cable can be up to 1000 meters for proper functioning.

6.3Adjustments

Microphone Pre-amplifier Gain Preset With the right hand side cheek of the Call Station removed, the microphone preamplifier’s gain can be preset. Turning the potentiometer (fig.6.2B) to the right increases the amount of gain. To obtain nominal 1 Volt output level, the gain can be preset from 84 to 114 dB SPL.

NOTE: The Call Station Input Modules also have input gain presets. The

Microphone Preamplifier Gain Preset should only be used for setting the amount of compression, not for lining up the Call Station output with the rest of the SM30 System. See ‘Built-in Compressor’ earlier in this chapter.

LED Intensity Preset

With the right hand side cheek removed, it is possible to gain access to the LED intensity preset.

To compensate for various local lighting conditions, the illumination intensity of the LEDs can be adjusted. Turning the potentiometer (fig.6.2A) to the right increases the intensity.

With the template and its cover in position, and the microphone volume and LED intensity adjusted, replace the right hand side cheek.

6.4Using the Call Station

Using the Keypad to make a Call

1To route a call to one or more loudspeaker zones, simply type in the number of each desired zone using the numeric keypad. Numbers ‘1’ to ‘9’ allow single digit numbers to be entered, number ‘1-’ is for tens, and ‘0’ is the second digit in the number 10. For instance, to route a call to zones 7, 10, and 15, type in: 7, then 1-, then 0; then
