Description

Sensitivity readers, voltmeters and multimeters are designed to assure smoke detectors are working within their listed and marked sensitivity ranges.

With the System Sensor i3 series sensitivity reader (SENS-RDR), an LCD screen displays a detector’s exact sensitivity by percent- per-foot obscuration. Therefore, unlike many sensitivity readers, voltmeters and multimeters that display only the voltage rating, the step of cross-referencing a voltage reading to a sensitivity range is eliminated with the SENS-RDR. Beyond displaying the sensitivity reading, the LCD screen indicates the status of the detector in alphanumeric text as GOOD, SERVICE or REPLACE.

Testing a detector’s sensitivity is a simple and quick task. The SENS-RDR connects to hand-held devices and threaded extension poles for those detectors installed out of reach, eliminating the need for a ladder. Within 10 seconds, the dual LED and sounder will alert the installer that the reading has been taken. With dual indicators, the installer won’t have to rely on a single LED in areas with visibility issues or a single sounder in areas with audibility issues.

The SENS-RDR operates with two AA alkaline batteries. To ensure these batteries are operable, the SENS-RDR has a low battery indicator. And, to maximize battery life, the SENS-RDR automatically shuts off after 30 minutes.
