Fire control panel and external alarms repetition for three different operators. Contains power supply and battery charger. Fire detection loop. Automatic extinction control circuit which provides a monitored output the activation of an electrovalve. Relay output (24 V). 12 VDC output (500 mA.) for several purposes outside the panel unit. 30 external alarm input control, normally open or normally closed selectable by a commutator, (outputs for 30 alarms through potential-free relays normally open or closed selectable by a selector). For the first 14 outputs plus fire alarm and generl fail alarm there are three Sub-D connectors of 37 pins to be used independently by each operator. This information is simultaneously repeated in the three connectors. For the remaining 16 outputs, there is a single Sub-D, 37 pin connector. Repetition by two commuted 2 A relays, voltage free in outputs 1 and 30. Control of 1 FIRE output and 1 GENERAL FAIL output normally closed through the 3 first Sub-D ,37 pin connectors. 2 A commuted relays, voltage free for: Fire alarm, general fire alarm (normally energized); Ventilation stop, selectable with fire level 1 or 2; Optical and acoustic signals, as well as the necessary controls to manage the installation.
