Extronic PD-22LF User manual

Presentation
The PD-22LF auxiliary detector is intended to be used
in combination with the PD-2200 IR detector in closed
premises that are difcult to monitor, for the control
of HF light ttings with a 1–10V input. It can be used
for detection in closed premises (with doors) where it
is not possible to monitor the entire premises with a
single IR detector. It is designed to be mounted in the
IR detector enclosure using the detector’s terminal
block
The PD-22LF auxiliary detector consists of an acoustic detector
that detects low frequencies (LF, 0–3 Hz) and a level selector.
The level selector switches between the normal light level of
around 80 per cent and a base level of around two per cent.
Operation in combination with PD-2200 IR detector
When someone enters the premises the lighting is switched on
at the normal level by the acoustic auxiliary detector or by the IR
detector. The acoustic auxiliary detector detects the infrasound
(0–3 Hz) that is generated when a door is opened. The advan-
tage of the acoustic detector is that it also detects entrance into
the stairway through doors that are hidden from the IR detector.
The lighting remains switched on at the normal level for as long
as presence is detected by the IR detector, plus a delay that can
be adjusted using a jumper on the auxiliary detector (2 sec, 10
sec, 30 sec, 1 min or 5 min). The lighting is then reduced to the
base level for the light ttings, which can vary from 1 to 10 per
cent. The base lighting remains on until the next time someone
enters the premises.

Note!
The photocell in PD-2200 cannot be used.
PD-22LF cannot be used in the PD-2400.
PD-22LF auxiliary detector detects the low-frequency sound that is
produced when a door opens.

2. Connecting
The PD-22LF auxiliary detector is connected directly by four
pins to the four terminals, “C, NC, -, and +” on the circuit
board in the PD-2200 IR detector; see illustrations.
Connection is easier if the leads are connected before
mounting the auxiliary detector inside the IR detector, see
wiring diagram below.
3. Setting up and adjusting
Setting levels and times
The potentiometers that control the maximum and minimum le-
vels should be adjusted as follows for a standard solution:
Max potentiometer (red) to maximum, 80 per cent. Measure
the voltage of the 1–10 V supply to the light ttings and adjust
this to a maximum of 8 V, or a suitable lower level.
The sensitivity of the acoustic detector must be adjusted. The
green LED indicates when low-frequency sound is detected.
Test the detector by opening a door in the monitored area. Ad-
just the sensitivity using the Sensitivity (yellow) potentiometer to
give reliable operation at as low a sensitivity as possible.
Also test doors in neighbouring areas that you do not want to
monitor, to minimise the risk of spurious detection.
The delay time is adjusted by placing the jumper over the pins
for the desired time delay, 2 sec, 10 sec, 30 sec, 1 min or 5 min.
This time determines how long the lighting remains on at the
higher level after each detection. This time should therefore be
kept as short as possible.
See the separate manual for setting up and adjusting the PD-
2200 IR detector.
