Note that only the following detectors can have their
sensitivity altered:-
VDOT-PY: Addressable Photoelectric Smoke Detector
VDOT-PYH: Addressable Multisensory Detector
VDOT-DPH: Addressable Dual Optical/Heat Detector
For the VDOT-PY (Addressable Photoelectric Smoke
Detector), the sensitivity can be set to Low, Normal or
High.
There can be different settings for day-time & night-
time.
For the VDOT-PYH (Addressable Multisensory Detector),
there are settings for the smoke sensor, and for the heat
sensor.
The smoke sensor can be set to Off, Low, Normal or High
(Note: setting to off will make the detector work as a
heat detector only)
.
The heat sensor can be set to Off or ON.
(Note: setting to
off will make the detector work as a smoke detector
only)
.
(Note: Setting both sensors to Off will turn off the
detector, so it will no longer report an alarm)
For the VDOT-DPH (Addressable Dual Optical/Heat
Detector), there are settings for the smoke sensor, and
for the heat sensor.
The smoke sensor can be set to Off or On
(Note: setting
to off will make the detector work as a heat detector
