GD-37
1. Description
The GD-37 is a programmable and manageable pre-recorded messages and background music player over Ethernet via a
built-in webserver.
Suitable for commercial uses as well as for security sound systems in venues with large numbers of people, where the
broadcast of automatic, emergency and evacuation notices (among others) is required.
The GD-37 digital recorder allows you to digitally record and play an unlimited number of and background music (depending
on the capacity of the SD).
From the front USB it also allows the broadcas of background music (BGM), having 2 play / pause and stop buttons on the
front panel.
Scheduled playback of messages via webserver through an internal calendar creating a series of events called "Programs" in
which the characteristics associated with the message are registered as per: Start Time, End Time, Cadence, Repetition,
Activation of remote control outputs, etc.
The Webserver installed in the equipment allows functionalities such as: complete supervision of operation, activation/stop of
messages, music and programmes, programming, calendar events, programming of remote events (remote controls),
configuration of operating parameters (day and time, volume, IP-Ethernet mode, on/off, etc.).
It includes 10 programmable GPIs to associate with events or programs and launch messages automatically. It also has 10
GPOs to associate with external equipment such as UDE amplifiers to trigger warning priorities or interact with the building
control system, etc.
The GD-37 incorporates two supervised security messages, which in case of failure the equipment indicates it visually via a
Fault indicator on the front, at the same time as it closes a fault contact on therear, which can be integrated in other control and
signalling equipment.
The power supply redundant to 230Vac (others on request) and 24Vdc, allowing it to remain operational even during power
cut-offs in the main power supply system.
