FAQ: I want to switch my alarm off at night, can I do this?
Please see a number of ways to do this:
Use the TCO-47, this is a timed cutout device that will disable the alarm for 4 minutes find details here
Use the NS-2 or NS-3 modules, these are double engage cut out devices. When reverse is selected twice in the specified time (2 seconds for the NS-2 & 3 seconds for the NS-3) the alarm will be disabled. The function is disabled when reverse is disengaged again. Details on these devices can be found here
