Architectural/Engineering Specifications
Sensitivity reader shall be a System Sensor model number SENS-RDR, listed with Underwriters Laboratories as a smoke detector accessory. The reader shall be
capable of reading the detector’s sensitivity without the need for a physical connection to the detector, and shall not require the use of a voltmeter or multi-
meter. The reader shall offer the capability of hand-held use or shall accept a threaded extension pole. The reader shall include an LCD screen which indicates a
detector’s sensitivity in terms of percent per foot obscuration and a textual status indication. The reader shall operate with two AA alkaline batteries and shall be
capable of indicating a low battery condition on the LCD screen.

Action
The detector is within its sensitivity range. No action is necessary at this time.
The smoke detector’s sensing chamber requires cleaning for continued reliable operation. Refer to the i3 Series manual for
proper maintenance procedures.
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 reader’s 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 first 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 finished, turn off the reader by pressing and holding the button for approximately 2 seconds until the reader sounds.
