agency listings i 3 ? series sensitivity reader system sensors i 3 series sensitivity reader displays sensitivity and status indication readings of all i 3 series detectors and other compatible system sensor smoke detectors. features an lcd screen that displays sensitivity by percent-per-foot obscuration connectors for a hand-held device or threaded extension pole dual led and sounder indicators a low battery indicator automatic shut-off after 30 minutes ? ? ? ? ? sensitivity readers, voltmeters and multimeters are designed to assure smoke detectors are working within their listed and marked sensitivity ranges. with the system sensor i 3 series sensitivity reader (SENS-RDR), an lcd screen displays a detectors 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 alpha- numeric text as good, service or replace. testing a detectors 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 wont 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 of after 30 minutes.

(225 grams) lcd status indications status indication action good the detector is within its sensitivity range. no action is necessary at this time. service the smoke detectors sensing chamber requires cleaning for continued reliable operation. refer to the i 3 series manual for proper maintenance procedures. replace the smoke detector is failing and should be replaced immediately. SENS-RDR operation 1. turn the reader on by pressing and holding the button for approximately 2 seconds until the reader sounds. the lcd will display the word ready. the ready status indicates that the SENS-RDR is ready for accepting data from a compatible system sensor smoke smoke detector. 2. place the reader by the smoke detector being tested. position the reader above the oval depression near the word paint (see figure 1). position the reader below the detector at an angle (see figure 2). a ledge and an anti-skid tip is provided on the reader to maintain the reader in place while it reads the sensitivity. 3. hold the reader in this position up to 10 seconds until the reader sounds and the readers red led illuminates. (note: if the reader does not sound after 10 seconds, verify that the reader is properly positioned, and the lcd displays ready.) 4. the led and sounder indicate a valid reading is received. the reader will automatically display two results. the frst is a percent per foot obscuration measurement, which is displayed for approximately 3 seconds, followed by a textual status indication. the reader will continue to display both results for up to 30 minutes, or until the reader is reset. 5. to measure the sensitivity of the next detector, reset the reader by momentarily pressing the button. the lcd will again display the word ready. repeat steps 2 through 4, as necessary. 6. when fnished, turn of the reader by pressing and holding the button for approximately 2 seconds until the reader sounds. or push recessed switch with a 0.18 max. diameter to ol led recessed test switch position SENS-RDR at an angle on the ov al area or at the chamber opening by the word ?p aint? figure 1: reader location a compatible system sensor smoke detector figure 2: position reader on a compatible system sensor smoke detector
