1. Basic wirings of a stand-alone door lock with inhibit authorization code and indication (fig. 2)
• Connect the 1N4004 as close as
possible to the lock in parallel with
the lock power terminals in order to
absorb the back EMF and to prevent
it from damaging the keypad. The
1N4004 is not required if the electric
lock is AC-operated.
• To avoid electrostatic discharges,
always ground the (-) terminal of the
keypad to earth.
• The green LED lights while the
keypad is striking the electric lock.
• The connection "output 3" to "output
1 disable" is optional. With this
connection, output 3 will be used as
an authorization control. You may key in user code 3 to stop the operation of the electric lock during daytime
or after office hours in order to prevent unauthorized access. Set output 3 in start / stop mode (programming
option 61) for on / off control. The red LED lights when the operation of the electric lock stops.
