Today I have been working at a customer’s house trying to find a problem with his intruder alarm. A wireless fault with some Texecom Ricochet devices. An intermittent “wireless signal jamming” error.
After three hours and much hair tearing out I finally realised what it was!
The customer had some old wireless fobs for the system. The batteries had gone flat so he’d just put them on a shelf. As the batteries had finally got to the point of total failure one of the fobs had begun transmitting constantly on the same frequency as the Ricochet hub.
We moved the fobs well out of the way and the fault immediately disappeared, only to return when we put them back.
Three. Whole. Hours.
At least now next week I can continue where I left off.
