EXHAUSTS
Exhausts from cars / trucks, lift trucks, lawn mowers, etc. influences smoke detectors (sensors). If windows and doors are open,
exhausts can "slip in" that way.
LACK OF MAINTENANCE
Smoke detectors (sensors) are influenced by their environment and become "dirty". In an analog system (like EBL512 G3) a Service
signal is given when it is time to exchange the smoke detectors (sensors) to new ones. The alternative is to exchange detectors at
given periods, to be on the safe side.
CHANGE IN ACTIVITIES OR WRONG CHOICE OF DETECTOR
If the activities in the premises are altered, the detector choice might also need to be altered. Due to special environments, see
above, an inappropriate detector type might have been chosen from the beginning and thus cause unnecessary alarms.
ACTIONS VIA EBLWIN
Choosing another type of detector can solve certain problems. Bear also in mind, that the coverage area can be different for differ-
ent types of detectors.
It is however not always the best action to change detector type. Here is a list of other actions, programmed via EBLWin, which can
be used:
• Another alarm algorithm can be used (e.g. during working hours).
• Alarm delay for smoke detectors / sensors can be used.
• Two-zone or two-unit dependent (co-incidence) fire alarm activation can be used.
• In an installation with addressable detectors / sensors (e.g. EBL512 G3), the affected detectors can be individually disabled (or
whole zones) for temporary work in the premises. Bear in mind that the smoke spreads, and consideration must be taken to
adjacent detectors / zones. Disablements can be done automatically via a time channel (built-in or external) or via menu (H2).
Automatic re-enabling can be used.
• If there is an alarm organisation for the personnel on site, the alert annunciation function can be used.
• Pre-warning can be used as information before a fire alarm is activated.
