that Maglock has power (do not power maglock from control
board accessory power terminals). If shorting lock's NO and
COM wires does not activate Maglock, then replace Maglock or
Maglock wiring (refer to Wiring Diagrams).
that Solenoid has power (do not power solenoid from control
board accessory power terminals). If shorting lock's NC and
COM wires does not activate Solenoid, then replace Solenoid
lock or Solenoid wiring (refer to Wiring Diagrams).
