III. Installation and Use Guide

PA-950 it is required to be installed on a clean, flat surface and firmly installed. At the same time, keep away from interference sources, such as air conditioners and other substances that generate noise.

PA-950 the vibration sensor head is a high-sensitivity piezoelectric element, which has been adjusted by the manufacturer when leaving the factory. Therefore, this disassembly, beating and self-debugging are prohibited.

PA-950 the sensitivity of vibration detector is adjustable, which is used to adapt to different environmental needs. If the "wind and grass" of the surrounding environment can alarm PA-950 vibration detector, you can try to lower its sensitivity. On the contrary, if the PA-950 vibration detector is too "slow", you can try to increase its sensitivity. (See note)

in addition, it is necessary to ensure that the electrical technical indicators of PA-950 are met, as follows:

the power input is10-16VDC, we recommend that you use 12VDC power supply.

Alarm Relay: 28V/150mA, so the power supply cannot be connected to its normally closed output terminal. Otherwise, the alarm relay will be burnt out.

Through the simulation test, make sure that the PA-950 function is normal. Method: Use a screwdriver to gently stroke or knock on the installation surface near the PA-950, and the PA-950 will send an alarm signal (the alarm light is on at this time).

Note: PA-950 vibration detector wiring and sensitivity adjustment are as follows:

1, wiring:

1-2: Anti-disassembly identification

3-4: Alarm output

5: power Supply (+)

6: power Supply (-)

2. J3, J4 used to adjust the sensitivity of the detector

100%: Q and M shorting highest sensitivity

70%: Q and P shorting

50%: N and P shorting

40%: N and M shorting

30%: no skipping short circuit lowest sensitivity
