Explanation of Wireless Alarm System


1.What is the working theory of wireless alarm system?

Every wireless alarm system is made up with one control unit (for controlling, like a brain) and
some sensors (for detection, like hands and feet) and sirens. When detecting intruder, sensors
will send signal to control unit. The control unit will activate siren to make alarm sound and at the
same time it can make a phone call to users.

2. What is its configuration and how it works?

We sell at a standard pack, which includes one control unit, one door sensor, one PIR sensor and two remote controllers, one AC- DC12V adapter and one user manual. Wireless sensors must be registered with control unit so that the control unit can recognize the sensors when they send signal to control unit.

3.What is the classification of wireless alarm systems?

Wireless alarm system includes GSM alarm system (dialing out phone numbers by GSM Network, which uses GSM SIM cards) and Telephone auto-dial alarm system (dial out phone number by telephone line). BT-101GSM ,BT-102GSM,BT-103GSM,BT-104GSM and BT-106GSM are GSM Home alarm. The rest are telephone Auto-dial alarms.


BT-101GSM ,BT-102GSM,BT-103GSM,BT-104GSM and BT-106GSM----GSM Alarm system, use SIM card to dial-out.

BT-105,BT-106,CK-236,CK-238,CK-2316,PA-748 and BT-107 -------Telephone line Auto-dial Alarm System. They need telephone
line to dial out alarm phone number for help.

4. How many sensors can a control unit accept?

For GSM alarm system, it can accept 4 sensors per zone, every host could program over 50 detectors at least. For Telephone Auto-dial Alarm (PSTN), it depends on different control unit.

Note: The Sensors mentioned above include door sensors,PIR motion detector,smoke detector,gas detector,etc.

5. What should I do if I want to add more sensors for a control unit?

We have already registered the sensors in standard pack with control unit before delivery. But if users want to add more sensors for this control unit, they must learn how to register more sensors.

The steps as follows:

I. For GSM Alarm system (BT-101GSM ,BT-102GSM,BT-103GSM,BT-104GSM):

Steps of registering:

When power on, the system will search the GSM Internet and when the LED is turned red which shows it finds the Internet. At this moment, you will have 20 seconds to register the sensors. For Door sensor, separate the two parts of the door sensor and remove them back when there is a beep from control panel, which shows successful. For PIR Sensor, switch the power button to the ¡°on¡±, it will beep and then turn it back to ¡°off¡±. For smoke and gas detectors, there are a black point inserted in the left side. Press it and it will beep sound from the control panel, which shows successful. That is all!

II. For Telephone Auto-dial Alarm (PSTN)

Different systems own different register way, you could contact us for details. Whatever it's very easy for you to do it.

6. How to trigger the sensors to make it register with control unit?

When the control panel is powered, start to register them. For door sensors, just remove the two parts of door sensor and remove back, it will beep and the status LED flashes, which shows successful. And for PIR Sensors, you can turn the switch to ¡°on¡± and the system will beep, which shows successful and then turn it to ¡°off¡± to avoid false alarm. For remote controllers, you can press any key on its panel (three keys on it), and the system also beeps. For gas and smoke detectors, there is a black switch on the left side; you can press it to register it with control unit. For break sensors, you can put it on a desk and then shake the desk, it will send a signal to control panel. The control panel will response with a beep sound, which shows successful. After finishing registering, please enter # to exist (two beeps.)

7. How long is the distance between sensors and control units?

80 meters in an open air (without block). Indoor use, it depends on the specific environment
