Hardware configuration 
The maglock peripherals consist of the following: 
•  Passive infrared motion detector (PIR) 
•  Request to exit (REX) switch 
The PIR is connected via the CRC input circuit. The REX is 
connected directly to the maglock instead of the CRC input 
circuit to meet NFPA requirements. 
SDU programming 
When programming the system for this application you’ll need 
to configure the CRC, defining the device type. You’ll also need 
to define the input circuits. For this application define the input 
circuit for the PIR as follows: 
•  Device type = Security interior 
•  Application = Request to exit motion detector.
