What is the 'Loop Response' in control panel programming?
Loop Response is the amount of time that a normally-closed circuit must remain open (or a normally-open circuit must remain closed) to trigger an alarm. The longer ("slower") the loop response time, the more immune the system will be to false alarms caused by building vibrations, power surges, etc.
Selectable Loop-Style Response Times:
- 50ms (0.05 seconds): Used for momentary panic buttons and area-protection devices such as photoelectric eye sensors, older PIRs, seismic detectors, floor mats, etc.
- 10ms (0.01 seconds): An extremely short ("fast") loop response time used mostly for 'window bug' glass-break sensors, and to eliminate the need for a pulse range extenders.
- 750ms (0.75 seconds): The longest ("slowest") loop time, recommended for use with magnetic contacts, window foil, motion detectors, etc.
Unless programmed otherwise, the default loop-style response time is 750ms for all zones.
