Abstract
A fire detecting system can mix fire detectors, such as smoke, flame, or, thermal detectors on a common loop, or zone, with gas detectors. Signals indicative of gas can have one amplitude while those indicating fire can have a different amplitude. Duty cycles can be varied to indicate other conditions, such as trouble conditions.
