All times are in seconds.

There is a minimum time delay of 2.3 seconds before acceptance of any new state except for a type 4 (DELAY) circuit with an into alarm time of zero, (D1=0), where the minimum time is reduced to .4 seconds (typically .4, minimum .2, maximum .8 seconds).

D1 and D2 are programmable to 0-250 seconds but if set to zero, a minimum delay of 2.3 seconds ( or .4) is still applied.

Hence for a type 4 circuit with D1=0, D2=5, the into alarm delay is .2 to .8 seconds and the out of alarm delay is 5.2 - 5.8 seconds. For a type 4 circuit with D1=30 and D2=0, the into alarm delay is 32.3 seconds and the out of alarm delay is 2.3 seconds.

Type 4 circuit with into alarm delay of zero

The into alarm time for both detector operated (alarm) and for mcp (instant alarm) is .2 to .8 seconds (typically .4 seconds). The delay into and out of fault and out of instant alarm is also .2-.8 seconds. The delay out of alarm is the out of alarm delay (D2) with a minimum of

.2-.8 seconds.

Note that programming an AZC for any time delay type resets programming of voltage bands B1 and B3 for that AZC to the default options. (These can be subsequently re-programmed, see Section 7.2.5).

SAD & Delay Types

SAD and Delay circuits (types 3 & 4) with D2 greater than zero, require non-latching detectors. The corresponding zones must also be programmed as non-latching.

AVF/RAD Sequence

Recognition of a detector's first operation occurs after 2.3 seconds. However, with AVF this does not generate alarm immediately.

A delay of 3.4 seconds occurs and then the circuit is reset for 5.3 seconds. The circuit is then re-energised and ignored for 2.3 seconds. The sum of the delay, reset and ignore periods (default = 11 seconds) equals the D1 value, with alteration of D1 only affecting the delay period. E.g. setting D1 to 30 will provide a 22.4 second delay, followed by the reset and ignore period.

If the detector re-operates in the following 150 seconds then an alarm is generated immediately. If it does not the sequence re-starts.
