1318 Relay activation module for message override
As local attenuators are used in high impedance lines (100 V, e.g.), the transmission of a message over the
loudspeaker which are regulated by the attenuator must be guaranteed, independently of its functional situation
(even if the regulator is off).
This type of installation uses a 3-wire connection, one for the 100V positive output, one for the negative (0V) and the
third one guarantees the message override through the switching of a relay in the
1318
.
This module has 3 relays to differentiate 3 different messages zones (areas). When setting up the zones, each
relay is assigned one zone automatically. Therefore, when setting up the installation and this module is
SETUP
,
the control console will show 3 assigned zones at a time.
Audio signal selection module 1509
1509 Audio signal selection module
This module allows to select one of the 5 audio signals that flow along general line (4 audio prog
messages), and isolate this selected signal through a 1/1 audio transformer thus making it possible to send
this signal to another device.
The more common use is to pick-up an audio programme and send it to the telephone switchboard as background music.
The connection between this devices output and the receivers audio input will be made using an audio shielded cable.
