NOTIFIER by Honeywell’s Pearl lies at the heart of a system designed to combat false alarms once and for all, even in conventionally difficult to protect environments.
The Pearl’s advanced programming features are designed to engineer out false alarms by utilising intelligent detection and programming options.
Type B dependency allows a zone to be defined for each individual flat that acts as if it were a separate system. On receipt of an unconfirmed fire signal from a flat, for example, only the local alarm within the flat is given.
If the alarm is confirmed by a second signal the system proceeds to the relevant evacuation stage (general alarm or part of staged evacuation). Alternatively, if the confirmation signal is not given the system may reset automatically without attendance by the warden or maintenance engineer. A confirmation signal may be given by; a second device in the same zone, a second signal from the same device (either after a certain time or from a different sensor within a multi-criteria detector), or a manual confirmation e.g. from a call point.
This scenario enables a single integrated fire detection and alarm system to be used where traditionally the risk of disruption from false alarms has outweighed the benefits. It also eliminates the need for the system to be manually reset once the nuisance smoke has cleared.
