Desi Steely is an alarm system specially designed for doors. It is invisible from the outside of the door after installation. The system has 2 different protection sensors; impact sensor and magnetic contact. Steely can be used with password by keypad on the device and by remote control.
There are 2 different protection sensors in the built-in alarm system:
IMPACT SENSOR: It provides alarm to the system in case of impact detection that passes through the meter and threshold value coming to the door. In this case, the malicious person will get away without harming your door.
OPENING SENSOR: Using the magnetic field principle, this sensor detects if the door has been separated from the frame and allows the system to alarm if the door is opened. Once the alarm system is switched on, the system will automatically start to alarm if anybody opens the door without using the remote control (including opening the door with the original key).
In fixed-code controls, the RF code is always the same when the button is pressed. DESi remote controls use rolling code technology. Rolling code technology works briefly as follows: 1) When you press the button of the rolling code control, an encrypted code is spread as RF. 2) When you press the same button again, a different RF code is spread in encrypted form. The same code dos not broadcast again. The DESi controllers are broadcasted at the frequency of 433.92 MHz which is approved by the Telecommunications Authority.
