8-3 - Technical zones
Double-knock technical zone
The prealarm or alarm of a single device generates a technical prealarm in the zone, the intervention of a second device causes a
technical alarm in the zone.
Double-knock zone prealarm timeout
It is possible to set the maximum prealarm time for the double-knock zones. If a zone in prealarm state at the end of the set
timeout has switched to stand-by state, the prealarm is automatically cleared. If, however, the prealarm condition persists, the zone
remains in prealarm state until the detector switches to stand-by or another detector of the zone switches to alarm.
The timeout can be set by steps of 5 minutes from 0 (in
fi nite) to 60 minutes.
N.B. The Behavior after prealarm setting can have an effect on the alarm release.
The prealarm and alarm outputs of the technical zone must be programmed, specializing the programmable outputs for these
functions.
Single-knock technical zone
The alarm of a single device (single-knock) is enough to generate a technical alarm of the zone and trigger the output speci fi cally
programmed for technical alarm. If a device generates a prealarm, the zone will switch to prealarm state.
