Wiring Diagram

Connection terminals:

L,    and N: AC220V power supply terminals

NC (normally closed), COM (Common) and NO (normally open):  (2 sets) output terminals for relay external control signals output terminals

S1, S2, GND, + 24V: System bus connection terminal

A, GND and B: RS485 communication interface connection terminals

1) Capacity: the total number of detectors and input modules externally connected to the controller shall be not more than 2.

2) In order to control external equipment, there are contact outputs for two sets of relays (namely, internal linkage modules) inside the controller.

The system default setting is that the two sets of relays will output signals whenever a detector gives an alarm.

3) Two sets of internal linkage modules can provide one of the following five output modes:

A. Passive switching value signal output: contact capacity: 10A/AC220V or 10A/DC24V

B. Passive jogging signal output: contact capacity: 10A/AC220V or 10A/DC24V

C. DC24V/200mA level signal output (NO+, COM-)

D. DC24V/200mA impulse signal output (NO+, COM-)

E. Capacitance output (NO+, COM-)

Special note:

Default: “Output 1” and “Output 2”are passive switching value signals.
