Door Strike Relay Specications
The 7073/7073A/7173 keypads provide one internal programmable Form C single
pole, double throw (SPDT) relay for controlling door strikes or magnetic locks. Three
wires on the 5-wire harness, Violet (N/C), Gray (Com), and Orange (N/O), allow you
to connect devices to the relay. The Form C relay draws up to 15mA of current and
the contacts are rated for 1 Amp resistance at 30 VDC maximum.
Wiring the 333 Suppressor
One Model 333 Suppressor is
included with the 7073/7073A,
7173 keypads. If the device being
controlled by the relay is connected
to the N/O and C wires, install the
suppressor on the N/O and C wires.
If the device is connected to the
N/C and C wires, install the 333 on
N/C and C wires. Refer to Figure 3.
Door Strike Relay Operation
As soon as the user code sent
from the reader is veried by the
panel, the keypad door strike relay
activates for 5 seconds. During this time, the access door connected to Zone 2 must
be opened to start the programmed entry/exit timer and zone Bypass.
Note: The 5-second door strike is programmable in the panel when the keypad is used
on a XR100/XR500 Series or XR150/XR350/XR550 Series panel. Refer to the panel
programming guide.
