Door Strike Relay Specifications
The 7573/7573A 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 7573/7573A,
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 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 programmed entry/exit timer and
zone Soft-Shunt.
Note:
The 5-second door strike is programmable in the panel when the keypad is used
on an XR100/XR500 or XR150/XR350/XR550 Series panel. Refer to the program guide
as needed.
