Please refer to either the M1XRFTWM or M1XRF319 or the M1XRF2H Installation Manual under supported sensors for more information on setting the OPT1, OPT2 or the LOOP # for the sensor. In general OPT1 and OPT 2 were features for the Interlogix Sensors in that when OPT1 was checked this indicated the internal Reed Switch was disabled so you could hard wire a contact and OPT2 determined if the hardwired contact was Normally Open or Normally Closed.
LOOP #’s are used with ELK Two-way Wireless Devices and Honeywell Wireless Devices. For the ELK Two-way sensors the Internal Reed will be LOOP 2 with the exception of the 6022 which is a Universal 3 Zone device with the option to hard wire two external contacts. The External Hard Wired Contacts will connect to LOOP 1 and LOOP 3 with LOOP 2 being the internal reed.
