Table 81: Zone Pulse Count Times
For zone pulse count time, options 0 – 7 have a zone loop response time of 20 ms. For zone pulse
count time, options 8 – 15 have a zone loop response time of 150 ms. Loop response time is the
length of time a zone must be unsealed before it can register as a valid pulse.
Inertia sensors should use options 0 - 7, while PIR detectors should use options 8 – 15.
24-Hour zones do not receive any handover pulses from other zones. 24-Hour zones may
handover pulses to other zones.
