98789 Remote Control Net Alarms

Ajax SpaceControl is a miniature key fob with accidental click protection. It allows setting the Ajax system in the armed, night or disarmed mode and switching on an alarm.
As it is the two-way communication, you will know whether the system has received the Ajax SpaceControl command.
Operating as part of the Ajax system, the key fob is connected to the hub via the protected Jeweller protocol. In addition, the key fob can be used to control any third-party security central unit through the uartBridge or ocBridge Plus integration module.
The key fob is set up through the iOS and Android-based mobile app for smartphones.

Using the key fob

Maximum connection distance between the key fob and the hub — 1,300 meters. This distance is reduced by walls, inserted oors and any objects hindering the signal transmission.
Ajax SpaceControl operates only with one security system (Ajaх or third-party via the integration module). If you connect the key fob to a new security system, it will cease to interact with the previous system. However, the key fob will not be automatically deleted from the list of devices of the hub.
The key fob can:

• Arm the system — press the button once
• Turn on the night mode — press the button once
• Disarm the system — press the button once
• Switch on an alarm — press the button once

To turn off the actuated security system (siren), press the disarming mode button on the keyf ob.
Accidental click protection is available on the Ajax SpaceControl with rmware version 5.54.1.0 and higher.

Key fob maintenance and battery replacement
When cleaning the key fob body, use any means suitable for equipment maintenance.
Do not use for cleaning Ajax SpaceControl any substances containing alcohol, acetone, gasoline, and other active solvents.
The pre-installed battery provides up to 5 years of operation of the key fob during normal use (one arming and disarming of the security system per day).
More frequent use can reduce battery life. You can check battery level at any time in the Ajax app.
Keep new and used batteries away from children. Do not ingest battery, Chemical Burn Hazard.
The pre-installed battery is sensitive to low temperatures and if the key fob is signicantly cooled, the battery level indicator in the app may show incorrect values until the key fob gets warm.
The value of the battery level is not updated regularly, but only after pressing one of the buttons at the key fob.
When the battery is discharged, the user will receive a notication in the Ajax app, and the key fob LED will slowly light up and go out red each time the button is pressed (key fobs with rmware version 3.16 and lower light up green).
