Re: How to connect the detector eol with alarm panel
Ensure the alarm panel and the detector are powered off to prevent any electrical hazards during installation. Most detectors have four terminals: two for power (positive and negative) and two for the alarm circuit (normally open (NO) and normally closed (NC)).
