alarm sensor

[howiechoo]

as we know , most alarm come with 1 socket for us to add a shock sensor or microwave sensor to add the security....but, is it possible to add more than 1 sensor if only 1 socket provided?

i think 1 sensor is not enuff..as it only can detect the movement when someone trigger 2 infra red line....but if the person lie down or lower their body when enter the car, the sensor wont do anything....

so any alarm sifu can help?

Yes, u can. There are usually 3 wires (sometimes even 4 wires) for the sensor, which are:-

1. Positive (usually red)
2. Negative (ground) (usually black)
3. Trigger (sometimes blue or green)
4. Warn away (might have for some sensors and alarms)

To add a second sensor, u have to check whether the new sensor is 3 wires or 4 wires. Then just tap the wires accordingly and u would be running 2 sensors parallelly.

Besides the motion sensor (microwave sensor), u can add also shock sensor (impact sensor) or even glass break sensor (audio sensor to detect glass break sound).

so that's mean i just add those sensor and connect it parellely according to +, - and trigger?

wat is the warn away?

 

[trex92]

yup... u can...

warn away is an additional output to the alarm just for the alarm to chirp (beep beep) and give warning but not trigger into full trigger. Some sensors and alarms have this.

[trex92]

ermm... u mean that is the central lock device? How come it has a plug in for sensors...? As i know, better alarm systems has got this feature like u mentioned that locks the door locks when u step on the brake or let go the handbrake, so in the end, it is the alarm that controls the auto lock function. But wat do u mean by brake lock system geh device...?
