NO POWER SUPPLY
MCRP 054 is a maintenance-free device. It requires uninterrupted
230 V mains power supply. Should there be power outage caused by
mains failure, the unit will generate the vent closing signal on output
terminals.
3.2. Alarm
The wind/rain sensor will automatically close smoke vents (or
prevent the vents from being opened by using the ventilation
pushbutton) if the wind or atmospheric precipitation is too strong/heavy.
When the weather monitoring unit is in the alarm mode, the red
LED will light up on its door, and the alarm signal will be generated on
output terminals.
In the alarm mode, the NO contact is open and NC contact is
closed with the COM contact.
The alarm will switch off automatically when the factor which
released the alarm ceases, after a period of time set by adjusting the
H1 (5) jumpers.
