Each input is active for closure to ground (Common GND).
Input Contacts are Normally Open (NO).
Input contacts are protected up to +42V compared to GND, an higher voltage can
seriously damage the relative electronic board.
Use cable with min section 0.5 mm, max 2.5 mm.
4.h Alarm messages activation monitored contacts
The system has two monitored dry contact inputs to trigger the EVACUATE and ALARM (alert) messages that are stored in the uSD
card. The connection foresees two resistors 2.2Kohm, connection example described in the figure below. (Alarm Input // Evacuate
Input).
As a factory default, both inputs will trigger their respective message at the opening of the contact (NC) and the playback will
continue cyclically as long as the input is open. Playback will stop at the closing of the contact.
These inputs, that are typically activated by the fire alarm control panel are monitored against short circuit and cable cut: in this
case, the system will trigger a fault warning.

Connect the resistors (supplied in the accessory bag) on each pair of contacts as shown in
the figure. The resistors must be placed at the end of the cable, from the smoke and fire
signalling station side.
Refer to the CONF ALARM INPUT MODE menu for the properties and configuration of the
input contacts.
The inputs of the alarm messages are, by default, configured for normally closed contacts.
Use cable with min section 0.5 mm, max 2.5 mm
If you do not intend to use the remote activation of messages, you cannot leave these terminals open without the device reporting a fault.
Therefore, connect two resistors 2.2Kohm directly on the mainboard terminal so that the device does not signal a connection fault or a Voice
Alarm.
