FEATURE

This detector provides Wo levels in addition to the basic normal and alarm lev-

els. The first is a HIGH SENSITIVI~

level that, when exceeded,

is communi-

catedto

the control panel meaning thedetector

maycause

false alams.

The

second is a LOW SENSITIVITY

level, also communicated

to the control Vinel,

meaning the detector may not be able to detect smoke. Supporting control lpan-

els use these maintenance

signals to effect prompt cleaning or replacement of

the malfunctioning

detector, which is uniquely identified at the control panf?l by

the detectots

polfing address.
