Security Alarm Control Siren Input Test

  1. Disconnect the 6P connector (A) from the alarm control siren (B).
  1. Inspect connector and socket terminals to be sure they are all making good contact.
    • If the terminals are bend, loose or corroded, repair them as necessary, and recheck the system.
    • If the terminals look OK, go to Step 4 .
  1. Make these input tests at the connector.
    • If any test indicates a problem, find and correct the cause, then recheck the system.
    • If all the input tests prove OK, go to Step 5 .
