WALK TEST
It is essential to perform a walk test to verify optimum detection coverage. To do this, first hold the
“
TEST
”
button on the PIR-3SP board down for at least 3 seconds, until the LED turns ON
→
OFF
→
ON, then release the button. Afterward, the PIR-3SP enters
“
TEST
”
mode for 3 minutes. Replace the
cover of the PIR-3SP, then walk into the detection area at normal speed, while observing the LED
indicator.
The LED stays ON normally, and turns OFF when motion is detected.
If the detection
pattern is not satisfactory, re-aiming the detector or adjusting the vertical pattern by sliding the PIR
board to -1 or 0 scale to test again.
Notes: 1. For the sake of convenience, the PIR is built in a reed switch; refer to its location on
Fig. 1. You may use a magnet to simulate the function of TEST button without opening
the case. When a magnet is placed close to the reed switch, the PIR responses as the
TEST button is pressed; refer to Fig. 5. And when a magnet is removed, the PIR
responses as the TEST button is released.
2. Test mode can be terminated before the 3-minute timeout by pressing the “TEST” button
again (or use a magnet to approach for a second) until the LED turns OFF. Afterward, it
returns to NORMAL mode.
3. In NORMAL mode, the PIR-3SP activates the transmitter when it initially detects
movement, then disables itself. The unit will resume operation only after about 3 minutes
with no further detection of movement. In other words, if installed in a heavy traffic area,
the PIR-3SP will not transmit until the area has been evacuated for 3 minutes. The
purpose of this feature is to reduce power consumption and prolong battery life.
RADIO LINK TEST
Open the top cover of the PIR-3SP and press the TEST button on the PC Board, or use a
magnet to activate the reed switch, to see whether the Base Unit can receive the radio signal.
PULSE COUNT SELECTION
The PIR-3SP is equipped with a programmable pulse counter that can be set by placing the
jumper on the desired setting (2 or 4). The PIR-3SP automatically overrides to one-pulse mode
while in "TEST" mode.
2 pulses:
This setting has high sensitivity of detection. Two pulses should be selected when the
detection range is longer (over 5 m)
4 pulses:
Alarm signal will only be sent if 4 pulses are detected within approximately 1 minute.
This setting provides the maximum protection against false alarms caused by all types
of environmental disturbances.
LED ON/OFF SELECTION
To prevent the PIR from being discovered by an intruder, LED can be disabled by putting LED
ON/OFF jumper at OFF position. Nevertheless, the LED is enabled automatically when the
PIR-3SP is in “TEST” mode, even with the jumper at the OFF position.
