Fire alarm contractors and building owners can now verify the compliance and reliability of conventional smoke detectors.
In order to comply with NZS4512:2021 clause 6.3.4, sensitivity checking of point-type smoke detectors must be carried out every year. Twenty percent of detectors such as the Honeywell 2151 series require annual sensitivity checks under these standards.
These conventional 2151 detectors’ compliance can’t be confirmed at the fire panel (analogue addressable detectors can).
The System Sensor i3 Series Sensitivity Reader assures that smoke detectors are working within their listed and marked sensitivity ranges.
Its LCD screen displays sensitivity by percent-per-foot obscuration. The reader also indicates detector status in alpha-numeric test as GOOD, SERVICE or REPLACE.
Whether it is hand-held next to the detector, or attached to a threaded extension pole for hard-to-reach detectors, the reader virtually eliminates the need for a ladder. Within 10 seconds, the dual LED and sounder alerts an installer that the reading has been taken.
Additionally the sensitivity reader indicates when its two AA alkaline batteries are too low in power. Battery life is maximised by automatically shutting off after 30 minutes of non-use.
The use of the sensitivity reader is the only way to confirm a detector’s sensitivity is within the manufacturer’s specified operating limits.
It should be noted that if sensitivity tests are not possible (or not carried out), then, under New Zealand standards, the detectors must be replaced every 10 years.
As the sensitivity reader is test equipment, Pertronic is providing it at a special price to installers and contractors at $880 + GST. We have stock available, under the product code SENS-RDR.
