Lock Controller Input Connections
1
DOOR: Door monitoring contact (can be assigned as N/C or N/O).
2
RTE: Request to Exit (default set to 5 seconds). *
3
Aux 1: Input - switch to 0v
–
Door Entry, open trigger from volt free relay of door entry
system (can be re-configured for trades. See Technical Support). **
4
Aux 2: Input - switch to 0v
–
Local Fire, local door only releases. **
5
Aux 3: Input - switch to 0v
–
Global Fire, all doors released system wide. **
6
N/C: Normally closed relay contacts 2 Amp Maximum.
7
COM: Relay Common 2 Amp Maximum.
8
N/O: Normally open relay contacts 2 Amp Maximum.
The auxiliary inputs above have been assigned their default function. However, functions can be
configured differently from the above. These are the defaults programmed by KMS for all
systems unless otherwise stated.
Inputs marked * require a momentary trigger to give an output. This means the system will not
allow another input trigger until the last is removed. For example, if the RTE goes closed this
contact must open again before another RTE input can be triggered.
Inputs marked ** can either be triggered momentarily or function with a held-on input. For
example, if AUX3 is held closed to 0v then the function continues to be triggered, in this case all
doors would remain open until the trigger is removed.
Test procedure
Set multi-meter to DC volts, measure between a 0v and an input - around 3.3v should
be shown. If NO voltage is read, suspect SHORT across input. i.e. RTE wired normally
closed.
