during the first 30 min. after a SHE-trig the actuators cyclically every 2 min.
Review of fuses
mains 1A slow-blow
actuator fuse 5A slow-blow
battery 630mA medium slow-blow
Type of connection to external
mains screw terminal / plug-screw terminals / 0.5-2.5mm²
Cable monitoring
automatic detectors (detector circuit with active end module), break glass unit
(detector circuit with end resistor), actuators (with motor end module), batteries
(cyclic measurement)
Message OK, fault and alarm
optically alternating or steady signals by LED's:
steady green LED = operating
alternating yellow LED = malfunction of battery(at battery voltage less than 19V
or above 29V), actuator, break glass unit or smoke
steady red LED = alarm (short circuit)
Automatic smoke triggering
Smoke triggering when temperature inside the compact unit exceeds 72°C
