automatic detectors (detector circuit with active end module), break glass unit
(detector circuit with end resistor), actuators (with motor end module), batteries
(cyclic measurement)
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)
