Secware2 Posted July 30, 2018 Share Posted July 30, 2018 Hello there i recently purchased some optex -70 sensors from yourself for replacement of the obsolete optex 100 plus ones.On going to install them I found that the old ones have more wires eight as the new 70 ones only have six. So I was looking to see if there is a way to convert the old ones to the new Quote Link to comment Share on other sites More sharing options...
Secware2 Posted July 31, 2018 Author Share Posted July 31, 2018 Based on the information you provided. It appears that you have replaced the TF model with a TN model. The TN model does not have DQ ( environmental disqualification, this can be used as a pre alarm or a shunt for the alarm to prevent false alarms) so in theory you can install the beams without it. It is also worth noting that the TF range has options for NO and NC contacts that the TN only has the options for NC. Quote Link to comment Share on other sites More sharing options...

Secware2 Posted August 1, 2018 Author Share Posted August 1, 2018 You can use the AX-100TF https://www.securitywarehouse.co.uk/catalog/cctv-c-1/detection-c-1_24/optex-4-channel-synchro-twin-30m-active-beam-nonc-relay-p-3367.html Quote Link to comment Share on other sites More sharing options...
