2000 SERIES SENSORS INSTALLATION GUIDE Revision 3.1 June 1997
Notes: (Combined with FP2000)
• At the fire panel this information can be programmed to be always available (On) or
only when the sensor is being polled (Blinking).
• When the complete zone is disabled, nothing will appear on the 7-segment display of
the disabled devices.
• The maximum number of 7-segment displays active at the same moment can be
programmed at the panel (in ‘On’ mode).
• The test conditions mentioned above are tests initiated at the panel and not from the
sensor itself (see paragraph 2.2.6).
2.2.6 Diagnostics and Sensitivity Test Modes
Diagnostic and sensitivity test modes are available on the 2000 Series Detectors. The
2000 Series Smoke Detectors provide obscuration or temperature information to the Fire
Panel. Obscuration or temperature is determined by the number of counts received at
the Fire Panel when a 2000 Series Detector is polled.
The DP2071, DI2072 and DT2073 models have a seven segment display that allows
sensitivity, diagnostic and address data to be displayed at the detector head. Holding a
magnet near the integral reed switch (Figure 8) will initiate the diagnostic routine at the
Fire Panel.
Figure 8 : Initiating the Diagnostic Routine
The following sequence will be displayed on the sensor :
First, the address of the sensor will be displayed (e.g. 35), followed by the real-time
value (e.g. 56), which is displayed twice.
