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 means of the keypad on the device as it is activated and deactivated by remote control.

Alarm Specifications

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 key or the original key).


Remote Contoller Specifications


 DESi uses rolling technology at the remote controller to prevent code copying.

Every time you press the button, the RF code will be different at 433,92 MHz frequency.


Manufacturing Technology

DESi, uses SMD (surface mount device) technology in its manufacturing line.


With this technology, instead of node soldering, components of electronic card are soldered from their surfaces. This process is done by robotic SMD placer.


As a result, electronic devices become more stable and durable to shocks.
