ALARM/ALERT MODULE
FUNCTION
the module.
In case you only hear the final part of the alarm/alert (this is caused by a higher priority signal occupying the system), the
system features a RETRIGGER option, which will retrigger the alarm/alert signal to hear it completely.

CONNECTING THE MSA2
In order to connect this module, you should follow the steps indicated on the figure of the next page:

Choose an operating mode with the jumper marked with nr.1: This module can act respecting the priority and zone system
(ALAR) or as BGA. Section two can't operate as BGA, only with priorities.
ATTENTION: You can have only one module acting as BGA. Remember that to work in this operating mode, you must
remove all zone assignment and priority jumpers.

MODULE USED TO GENERATE TWO ACOUSTIC ALARM/ALERT SIGNALS IN THE
SELECTED ZONES RESPECTING THE PRIORITY SYSTEM.
DESCRIPTION
Each alarm activates independently with an external signal (START). The duration of the
acoustic alarm/alert can be programmed in three ways:
Manual: as long as the START signal lasts

Always: Once activated, it can only be disabled with the STOP button

Temp: between 5 and 15 seconds, internally adjustable

The TEST/STOP buttons are used to test the module. They are difficult to access in order
to avoid accidental operation or manipulation.
The alarm/alert signals of the modules section 1 can respect the priority system or not. If
you configure the module to operate with priorities, the zone and priority structure will be
regarded (the alarm/alert signal attenuates the BGM). If you configure the module to work
without priorities (BGA) the signal will be mixed with the BGM and will be attenuated
together with the music in case that a message arrives (spoken message or alarm).
Internally you can select three alarm types and two acoustic alert types for each section of
