Questions for Solar-powered wireless infrared grating
1.Are your devices functional in low temperature (-2 to 15 degrees) in winter time, (17 to 35 degrees) during summer time?
Our detector supported working temperature range :-30C~70C. Can work at extreme snow weather condition such as Russian, USA.
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.I need to know how to match the beams with each type of system and how they work?
Firstly: turn on the sensors
Secondly: set the alarm host into coding status
Thirdly: trigger the sensor, so the alarm host can remember the sensor
4.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.
5.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.
6.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.
7.But I’m wondering if the sensibility could be adjusted?
Most of our sensors’ sensitivity can be adjusted by customers. Kindly attention that unusual sensitivity will result in false alarm, such as free falling object.
8.The IR beams works at 433 MHz?, Could work with other alarms also at 433MHz, or only with your alarm host?
The sensors adopt 433MHz (FSK+FHSS technology) 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.
Moreover, the code modulation of our detectors is private protocol, so the detectors are hardly directly match up with third-party 433Mhz alarm host.But we have two ways to contact with third party host.
Firstly ,we have switch outputs adapter to convert wireless signal to wired signal to third-party host(on condition that third-party host has wired zones)
Secondly, Send detailed technical parameters of your host to us,we’ll adjust our sensors and pair with your host ,but that will reduce wireless distance and anti-interference function.
9.What happens if a bee, or a bird passes through the IR-fence?Bee or bird flying cant trigger the sensor?
Bee or Bird flying will not trigger the sensors
Firstly, if obstacle freely falls and pass through defense area, sensors will not alarm.
Secondly, if 3 infrared holes can’t completely blocked by material, sensors will not alarm.
So, compared with other sensors,our products more effective in reducing false alarm.
10.Works in the light for UK climate?
Firstly, Our solar panel is made of amorphous material. It can convert light to electric even in cloudy or rainy days,without any direct sunshine. While at rainy days ,the solar panel can generate 2mA current to the battery .
Secondly, the static power of our sensors is only 1% of traditional wired sensor(static power:0.5mA). the sensors have high-capacity LFP battery inside,can keep the sensors working much more than 15 days without charging.
11.Also please confirm if the wireless link is one way or duplex?
Our wireless link is one way, that is to say sensors transmit wireless signal to host , but host cant send signal to control the sensors. While our sensors will self-check every 2 minutes, if any problem (e.g. low-battery、invalid、light interference etc.) ,Sensors will immediately report to host.
