JA37-300
Aural Message Generator - 3 Channel - Analog Inputs
SECTION 3 – OPERATION
3.1
Introduction
This section contains the operating instructions for the JA37-300.
Note
: The JA37-300 has no integrated operator controls. However, a remote-mounted mute switch or button
may be installed, which affects the operation of the unit.
3.2
Mute Switch/Button
If the JA37-300 is playing Alert messages (either because an alert input is active or when Power On Self-Test is
occurring), momentary activation of the remote Message Mute switch or button stops all messages from playing until
the next message is triggered.
3.3
Message Active Output
If an external annunciator is installed and connected to the JA37-300’s MESSAGE ACTIVE OUTPUT, the annunciator
will illuminate while any message is playing.
