Security Input
The security input can be used with magnetic reed switches, passive infrared detectors or any other security device that provides a normally open or normally closed contact. The security input may have several normally closed accessories attached in a chain. If the contact on any of the accessories on the chain opens, the input will go into alarm.
To install an accessory to the security input follow the diagram below:
