Ajax DoubleButton — wireless emergency button. Safety management with comfort
Ajax DoubleButton is a wireless emergency button with an advanced level of protection. Using such a gadget indoors prevents the possibility of a false response to various threats due to a well-thought-out logic.
The emergency button is an addition to the security system, which will report the threat and actively resist it. The user can set up additional functions triggered by the signal: sirens, shutters, electric locks, etc.
The emergency button transmits a signal to the Ajax Hub via the two-way Jeweller radio protocol. The range of the device to the Hub security system is up to 1300 meters. Jeweller protects the transmitted data with a cypher and eliminates the forgery of the device. If network failures or interferences are detected, the system switches to free radio frequency and informs users and the security company about the situation. The emergency button confirms the successful delivery of the alarm signal by the green LED on the housing.
The installation of an emergency button is recommended for both commercial and residential premises.
The main advantages of the Ajax DoubleButton emergency button
No accidental clicks
To raise the alarm, you need to press two DoubleButton buttons simultaneously. Accidental pressing is excluded, as the buttons are tight and separated by a partition. If you press only one of the two buttons — the alarm will not work.
Use different combinations of button presses to confirm the alarm. This arrangement ensures that the system user raised the alarm and did it intentionally. It is not possible to select the alarm type in this device. Also, it is essential to note that the button works 24/7 — pressing DoubleButton will raise the alarm regardless of the security mode.
Alarm delivery guarantee
The range of the emergency button is connected to the Hub control panel — up to 1300 m. The signal is transmitted using the two-way radio protocol Jeweller, which protects the transferred data with a cypher and eliminates duplication. If interference is detected in the network, the Ajax system looks for a free radio frequency to connect and notify users.
The success of the delivery of the alarm with the emergency button DoubleButton, confirms the flashing of the LED on the device’s body.
