Two Wire Detectors
Table A-2 lists two-wire smoke detectors that are compatible with the fire control panel. The table is organized
by manufacturer. The columns show the number of detectors per loop that can be used.
Note: The maximum number of smoke detectors per zone is determined by both the current draw and the imped-
ance of the smoke detector. If too many smoke detectors are used on any zone, false alarms could occur.
Do not mix different models of detectors on any zone; false alarms could occur.
Control unit Smoke Reset Time must be programmed for a number greater than or equal to the maximum
reset time of the smoke detector.
