TELE AID backup antennas, function - GF82.95-P-4102-04PM

In the event that the output of the telephone antenna (A2/22) decreases or the antenna is destroyed the system automatically switches over to the emergency call system left backup antenna (A2/54) and the emergency call system right backup antenna (A2/55). The emergency call system control unit (N123/4) decides which antenna is to be used for the emergency call.

The signals received by the emergency call system left backup antenna (A2/54) and emergency call system right backup antenna (A2/55) are relayed discretely via a coaxial cable to the emergency call system control unit (N123/4) and vice versa.
