User's Manual

V3d Product Specification, Version 2.06
a logger record is to be immediately generated and sent to the IMB. The measured value is a
peak of the sensor output over the previous interval.
The sensor is re-armed after the sensor level returns from the alarm state. At the point where
the sensor level crosses the threshold back to a typical level the sensor alarm is once again
active.
3.1.2.3 Configuration
The threshold shall be user programmable, changeable over-the-air through either network or
locally. Also the threshold can be disabled, such that no event message is generated.
3.1.2.4 Mounting
The acoustic sensor is mounted on a PCB inside the enclosure.
3.1.3 Door Sensor
3.1.3.1 Performance
The sensor is a reed-based, magnetic proximity sensor, implemented as a single pole, single
throw (SPST) normally open contact switch. When the actuator is nearby, defined as within
0.25 and 0.7 inches (6.35 to 17.8 mm), the circuit is closed. Otherwise the circuit is open, and
the door is considered open.
3.1.3.2 Function
The sensor output shall be sampled by / reported to the microprocessor at the configurable
sensor sampling rate of range from 1 to 60 seconds, or edge triggered, even when the V3d is in
its lowest power state.
Following first indication of a possible change of state, the sensor is sampled for an additional
number of seconds, and an event is declared only after all consecutive readings indicate such.
For a door open event, the V3d immediately generates a logger record and sends to the IMB.
For a door close event, the V3d only generates a logger record. The door sensor is immediately
re-armed after any event.
3.1.3.3 Configuration
The minimum number of consecutive readings shall be user programmable, changeable over-
the-air through either network or locally. Also the consecutive threshold can be disabled, such
that no event message is generated.
3.1.3.4 Mounting
The door sensor is mounted adjacent to the door top opening, with the actuator mounted on the
door itself. A short cable connects the door sensor to the V3d.
