Unit developed and made by AGUILERA™ ELECTRÓNICA through UNE EN54-2 standards to control fires, technical signals and other parameter changes which occur in mobile phone booths and similar facilities. Contains a stabilized power supply, powered at 230 V with input protections, 27 and 12 VDC outputs and a battery charger. Monitored loop which controls a detector and fire switches zone, with signaling of: 1st level of fire, 2nd level, breakdown and service. Monitored loop for automatic fire extinction, programmable to release the extinguishing agent with the 1st or 2nd fire level. Relays: for fire, general breakdown supervised, air conditioned pause and repetition of external alarms, 1 and 14. Controls from 14 to 30 depending on the model. These inputs are individually selectable by contact, normally open or closed, which are transmitted by sub D37 pin connector ( 2A relay outputs, voltage free by individually selectable contact, open or closed). Measures: 375 x 280 x 130 mm.
