WIRE THE ELECTRONIC LOCK
The 7073-WINT keypad provides a Form C (SPDT) relay for controlling locks
and other electronically-controlled barriers. The Form C relay draws up to 15 mA
of current and the contacts are rated for 1 Amp at 30 VDC maximum. The three
terminals marked
NO C NC
allow you to connect the device wiring to the relay for
module control. Use an additional power supply to power magnetic locks and door
strikes. See Figures 5a and 5b.
WIRE THE 333 SUPPRESSOR
Use the included 333 suppressor with the keypad to suppress any surges caused
by energizing a magnetic lock or door strike. Install the 333 across the keypad
C
(common) and
NO
(normally open) or
NC
(normally closed) terminals. If the device
being controlled by the relay is connected to the
NO
and
C
terminals, install the
suppressor on the
NO
and
C
terminals. Conversely, if the device is connected to the
NC
and
C
terminals, install the 333 Suppressor on
NC
and
C
terminals. See Figures 5a
and 5b.
