General Operation
The UNIT ALARM panel is a device that can be applied to any system where it is necessary to have alarm signals even in the absence of mains power. In the presence of 230V mains power supply, the battery contained inside the UNIT ALARM panel is kept in charge automatically by adjusting the charge according to the state of the battery itself.
It is advisable to carry out a test test periodically to check the correct functioning of the panel by holding down the TEST button to momentarily activate the acoustic and, if present, visual signalling.
When the NC and NO inputs change state (NC opens and NO closes) the audible and, if present, visual alarm is activated (flashing red).
It is possible to set UNIT ALARM so that the siren switches off at the end of the alarm condition or that it continues to acoustically signal the alarm until the intervention by the operator, who can decide whether to reset the alarm by pressing the RESET key or switch off only the buzzer and flashing light signals, leaving the red LED on to indicate that the anomaly has not yet been resolved, by pressing the SILENCE key.
Its also possible to set an internal timer adjustable from 25 to 120 seconds for the programmed switch-off of alarm signals.
GSM Version
Unit Alarm is available in the GSM version, that is supplied with a kit that includes an antenna and a programmable transmitter for signalling the activation of the alarm to cell phones.
