Operating Instructions—IFC-200 Operating Instructions 13
An Action prealarm is indicated if a detector exceeds the action level
threshold. When this occurs, all functions of the alert level occur, plus a
special Action software zone (5th zone) may be activated if programmed.
Prealarms latch until reset. A typical Action prealarm display appears
below:

The IFC-200 includes a crystal time base clock that provides time-of-day,
date, and day-of-week. The clock IC includes its own lithium battery
backup. Time is normally displayed in U.S. format, with 12 hour time and
month/day/year, but may be programmed for European time format with
24 hour time and day/month/year.
Zones 95 and 96 are reserved for control-by-time functions. These special
zones may be programmed to activate at one time-of-day and de-activate
at another time, and may do so for only certain days of the week. Any
control point may be turned on and off (lighting control, set-back
thermostat, etc.), by using one of these zones. These functions are
intended for ancillary (non-fire) applications.
When either Zone 95 or Zone 96 activates, it sets detector sensitivity to its
3.0% maximum (least sensitive) level. When the zone deactivates, the
sensitivity returns to its programmed setting. For day/night sensitivity
purposes, Zones 95 and 96 may be thought of as day zones.
Zone 97 is reserved for setting holidays (up to nine days). When the
present date matches any one of these nine dates, the zone activates. This
function controls special days of the year and is also used as the eighth day
in the programming of Zones 95 and 96.
