-Mag Lock Circuit-
LED = Mag Lock
24v Power Supply
Relay Controlled Circuit
(upper right half of the circuit)

-Controller Circuit-
Power supply
Push Button (at Reception Desk, etc.)
25uF Capacitor = 6 sec. Timer control for Relay
Add Capacitors with SPST switches to increase time.
25uF + 15uF = 9 sec.
25uF + 15uF + 10uF = 12 sec.
(lower left half of the circuit)

-Instructions-
Push the mommintary button to deactivate the Mag lock (change timer by changing capacitor size and/or input voltage)
