CLIMATIC CONDITIONS
Requirements and performance of the control unit complying with the CEI 79-2 standard are assu-
red according to the following climatic conditions:
• Reference temperature and relative humidity: 25°C – 65% R.H.
• Operating room temperature range: -10°C to +50°C
• Max. relative humidity: 90% at +35°C
• Altitude: 2000m a.s.l
References standards
• Parts with wire connections: in conformity with the 1st level of performances according to
CEI179.2 where applicable.
• Parts with radio connections: validation of the Post Office and Telecommunications Department.
The control panel is in conformity with the general rules for emission (EN50081-1) and immunity
(EN50082-1) certified by the Competent Body (part equipped with radio connections).
POWER SUPPLY UNIT
The power supply unit housed in the control unit is equipped with two outputs:
• Output for the system power supply through a wire and internal battery recharge, 13,8 V dc
(terminal 1).
• Output for battery recharge of the self-powered siren, 14,5 V dc (terminal 7)
The power supply unit’s output is electronically protected against all overloads.
The overall current on the two outputs must not exceed 280 mA.
In addition, two electronic protections against overloads and short circuits are foreseen:
• PTC1 (0,7A): protection of the system power supply output and siren control
• PTC2 (0,7A): protection against all polarity reversals of the battery
In order to simplify the calculation of the total absorption for the wire part of the system, consult the
