7073 Door Strike Relay Specifications
The 7073 keypad provides one internal 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 its contacts are rated for 1 Amp at
30 VDC maximum.
Wiring the 333 Suppressor
One Model 333 Suppressor is included with the 7073 keypad. Refer to Figure 3 and install the suppressor across the
5-wire output/reader harness Common (C) and Normally Open (N/O) or Normally Closed (N/C).
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 Suppressor on N/C and C wires.

7073 Door Strike Relay Operation
As soon as the user code sent from the reader is verified 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 40-second entry/exit
timer and zone Soft-Shunt. See the timeline shown below.
Note
: The 5-second door strike is programmable when the keypad is used on an XR200-485, XR500 Series, or XR2500F
panel. Refer to the XR500 Series Programming Guide (LT-0679) or the XR200-485 Programming Guide (LT-0196).
7073 Zone 2 Door Contact with Soft-Shunt™
If the door being released by the keypad is protected, you can provide a 40-second shunt by connecting its contact
to zone 2 (White/Red pair) on the keypad and enabling the Soft-Shunt feature. See ZONE 2 SHUNT in programming
and 7073 Door Strike Relay Specifications in this document. As illustrated in the Figure 4 example, once the door
strike relay is activated, the user has 5 seconds to open the door connected to zone 2. The zone is then shunted for
40 seconds or until the contact restores to normal. Door contacts may be N/C or N/O.
Note
: The Door Strike time is programmable when the keypad is used on an XR200-485, XR500 Series, or XR2500F
panel. Refer to the XR500 Series Programming Guide (LT-0679) or the XR200-485 Programming Guide (LT-0196).
