Use for Access Control
Magnetic Lock and Door Strike Wiring
The 7073/A and 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 normally closed (N/C), gray common (COM), and orange
normally open (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 at 30VDC maximum.
