CHAPTER 3: CAL USER PANEL

CAL Factory Presets

A summary of the beam settings for the CAL factory presets

is shown in Table 2. CAL ships from the factory with these

presets loaded into the loudspeaker. The presets can be

edited and overwritten with the Compass control software.

For more information, refer to the Compass documentation

included with CAL (also available at www.meyersound.com

NOTE: Factory presets 3 and 4 are blank and if

selected will yield no output for the loud-

speaker.

Fault Contact

The Fault Contact pins report when CAL shuts down or is no

longer active. When CAL is powered on and working nor-

mally, the NO (normally-open) pins are open and the NC

(normally-closed) pins are shorted together. When the loud-

speaker is powered off, its internal relays switch so that the

NO (normally-open) pins are shorted and the NC (normally-

closed) pins are opened. The three Fault Contact pins are

provided to accommodate monitoring for either short cir-

cuits or open circuits.

Override and Mute

For installations where CAL is part of a fire alarm or evacua-

tion system, the loudspeaker’s active audio input (main pro-

gram source) can be muted or replaced with an override

input (alarm or emergency announcement source). The mute

or override can be triggered with a relay closure attached to

the Mute or Override pins.

The Mute pin is triggered when it receives a voltage of 3 to

20 V DC greater than its associated COM pin. When trig-

gered, the Mute pin instructs CAL to mute its audio output.

The Override pin is triggered when it receives a voltage of 3

to 20 V DC greater than its associated COM pin. When trig-

gered, the Override pin instructs CAL to override the active

audio input with the override input. Both the active input and

override input are specified in the Compass control soft-

ware.

+5 V DC Power Source

CAL offers a local +5 V DC power source as a convenient

means for controlling its Logic I/O features. The +5 V DC

pins provide an isolated +5 V DC output that can be con-

nected to any of the Logic I/O pins through an external relay

or switch, eliminating the need for an external control volt-

age. The +5 V DC pin is fused at 0.35 A.
