Before Using
The SENS-RDR sensitivity reader is a tool to measure the
sensitivity of i3 smoke detectors as well as 100 series con-
ventional smoke detectors (only models 2151 and 2151T
manufactured after April 2006). It CANNOT be used on the
200, 300, 400, 500, or 800 Series detectors.
NOTICE: This manual shall be left with the owner/user of
this equipment.
IMPORTANT: Use of the SENS-RDR is designed to “...assure
that each smoke detector is within its listed and marked
sensitivity range...” per NFPA 72. The SENS-RDR CANNOT,
however, initiate a detector/sensor alarm. Sensitivity testing
shall not be used as a substitute for smoke entry testing.
General Description
This battery-powered device is equipped with an infrared
optical interface for reading data automatically sent by the
smoke detector every ten seconds. The SENS-RDR decodes
the sensitivity and status data, and displays the informa-
tion on its LCD display.
The SENS-RDR may be used either as a hand-held device,
or with a standard threaded extension pole.
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 accept-
ing data from an i
3 Series smoke detector.
2. Place the reader by the smoke detector being tested. Posi-
tion the reader at an angle on the oval area or at the cham-
ber opening by the word “PAINT” (See Figures 1 and 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 re-
ceived. The reader will automatically display two
results. The first is a percent per foot obscuration mea-
surement, which is displayed for approximately 3 sec-
