FAQs
What is included in the Ajax Baseline Kit 2?
The kit contains one Hub 2 (2G) Jeweller control panel, two MotionProtect U Jeweller PIR motion detectors, one DoorProtect U Jeweller magnetic opening detector, two SpaceControl Jeweller keyfobs, one HomeSiren U Jeweller indoor siren, and one StreetSiren DoubleDeck Jeweller outdoor siren.
Do I need professional installation?
All devices are wireless and battery-powered, and can be installed without specialist tools. However, for monitored installations connected to an alarm receiving centre (ARC) or for compliance with PD 6662:2017, professional installation and commissioning by a qualified security engineer is recommended.
Can the system be connected to an alarm receiving centre (ARC)?
Yes. The Hub 2 (2G) supports connection to a central monitoring station via SurGard (Contact ID), SIA (DC-09), ADEMCO 685, and other proprietary protocols. The system is compliant with EN 50131 Grade 2 and PD 6662:2017, making it suitable for professionally monitored installations.
How is the system managed and controlled?
The system is managed via the Ajax app, available for iOS and Android. Installers and security companies can use the Ajax PRO app or Ajax PRO Desktop for advanced configuration. The SpaceControl keyfobs included in this kit also allow quick arming, disarming, and night mode selection from the keyring, without needing a smartphone.
What happens if the broadband connection fails?
The Hub 2 (2G) automatically switches between Ethernet and cellular (2G/3G) connections. If the primary Ethernet connection is lost, the hub fails over to the SIM card connection instantly, ensuring the system remains communicating with the ARC and app users at all times.
Can I expand the system beyond the devices in the kit?
Yes. The Hub 2 (2G) supports up to 100 wireless Ajax devices, including additional motion detectors, door contacts, smoke detectors, flood detectors, keypads, range extenders, and more. The system can be expanded over time by adding compatible Ajax Jeweller devices through the app.
How long do the batteries last?
All wireless devices in this kit are rated for up to 5 years of battery life under normal operating conditions. Battery status is monitored continuously by the hub and reported in the Ajax app, with advance low-battery notifications sent to users and installers.
Is this kit suitable for outdoor use?
The StreetSiren DoubleDeck Jeweller outdoor siren is rated IP54 and designed for external installation. The remaining devices — including the hub, motion detectors, door detector, and indoor siren — are designed for indoor use only. The Hub 2 (2G) should be installed in a secure, sheltered indoor location.
