Beam system is active infrared detector. It is consist of transmitter terminal, receive terminal, Optical lens, LED indicator for light intensity etc. The system works as invisible light wall. When someone is entering into the light wall, it blocked the beams. Then the detector triggers alarm for warning and notice. The beam system keeps working 24 hours.

There are three types beams system. They are infrared beams, infrared grating, and infrared light wall. They are applied at different situation. Infrared beam is installed on wall or fence. It has 3 beams or 4 beam, 6 beams and length is short compared with other two types. So, it should be installed over the wall or fence or with bracket and pole to get enough protection height. But it has maximum 100 meters detection length. Infrared grating is used for windows, balcony or gate. It has 4 beams or 8 beams and with 620 mm to 1200 mm. The detection distance is 10 meters only. Infrared light wall is used for fixing on ground and can have lamp on cover.

1. Are your devices working at low temperature (-2 to 15 degrees) in winter time, (17 to 55 degrees) during summer time?

Our detector supported working temperature range :-30C~70C.

2,Are these solar alarms compatible with ademco alarm systems?

We total have 9 sets of alarm host:

Ademco available:HB-BJQ560-A; HB-BJQ560-B; HB-2020C;HB-3030C;HB-G250.

Ademco unavailable: HB-MFR;HB-2020A;HB-3030A;HB-G10

3,what distances can products achieve?

The infrared detection distance for infrared beam is 100 meter, for infrared grating is 10 meter and for infrared light wall is 20-50 meter. The wireless transmission distance is 800-1000 meter. It meets FCC and CE certificate.

13,What is the mechanism your system uses in order to detect stealing of sensors or jammer the signal in order to tamper the system?

Firstly, the working principle of our sensors is Active infrared detecting, so if any terminal is moved or damaged, sensors will report to host at once. Same time,host will indicate abnormity (e.g. alarming ,invalid , light interference).

Secondly ,the wireless transmission technology we made is FSK + FHSS technology,it has strong ability to anti-interference.( e.g. once sensor was Triggered), it will send 3 signals to host (3 different frequency points),and host can receive these signals independently. This anti-interference technology makes our products more competitive in same line.

14,Do they check status with the sensors , like a test signal? How often?

Our solar sensors will self-check every 2 minutes, if any problem (e.g. low-battery,invalid, light interference etc.) ,Sensors will immediately report to host.

15,Do your sensors have anti-masking features?

The sensors adopt FSK + FHSS technology,it has strong ability to anti-interference. i.e. once sensor was triggered, it will send 3 signals to host(3 different frequency points),and host can receive these signals independently. This anti-interference technology makes our products more competitive in same line.

16,Do the sensors come with the brackets?

Brackets for sensors are not included in package. If necessary, we'll configure brackets to your order,but it's better to purchase in your location, common size is OK.

17,What frequency is this transmitting on and do you have GSM notification by text to cellphones for your products?Our frequency 433MHz (FSK+FHSS technology) once sensor was triggered, it will send 3 signals to host(3 different frequency points),and host can receive these signal independently. This anti-interference technology makes our products more competitive in same line.
