7.1 Monthly Inspection Schedule



Inspect the transmitter for damage to keypad and case.



Inspect all electrical and antenna connections to ensure they are clean and tight.



Ensure all terminal strips are firmly in place.

7.2 Transmitter Troubleshooting

The transmitters have an LED status indicator to aid in troubleshooting. Due to the rough treatment it may

be subjected to, most problems are likely to occur in the transmitter. Thoroughly diagnose the transmitter

before proceeding to the receiver.

WARNING: When testing the transmitter, the receiver may become active resulting in system

operation. Always assume the system is working and will respond when testing a transmitter.

AVERTISSEMENT: Lors d’essais de fonctionnement du transmetteur, le récepteur peut être active

et provoquer la mise en marche du système. Toujours considérer que le système fonctionne et

qu’il répondra aux essais du transmetteur.
