Advanced connections
INT Lock – Used to operate a door in conjunction with another keypad. 24v dc max voltage,
100mA sink.
O/P1 inhib – When closed, this disables all codes for relay group 1.
Commonly used connections
Outputs – This keypad has 3 outputs. All can be
programmed for momentary and latching operation.
For gate systems and AC strike locks, connect a
keypad relay (normally open) in parallel with the
transmitter module relay. For magnetic locks, connect
in series with normally closed contact.
Egress – This is for an optional exit button input,
connected across this terminal and GND (-).
Never drill holes in the top of
the enclosure. Cable entry
should be through the
bottom.
