1.5 Connection Circuit
System ESIM021 and security unit COM must be connected.
ESIM021 can be powered from battery. The battery capacity shouldn‘t be higher than 7Ah.
Inputs Z1 and Z2 are connected to security unit PGM outputs if PGM are implemented as open
collector circuit or any other circuit and if it commutates with COM.
It is also possible to connect Z1 and Z2 inputs to, for instance, motion sensor or any other sen
-
sor as well as automatics device provided the inputs are commutated with COM.
1.6 System installation
The system box should be fixed with four screws to the wall. Since the ESIM021 has integrated GSM antenna, it should not be
installed into the metal box. For the connection of power supply, output and inputs connectors should be used 1 thread 0,5mm2
cable. Cables should be connected to the connectors and brought through the special cover hole for cables.
