Ajax FireProtect 2 AC White Wireless Heat/Smoke/CO Fire Detector

Ajax FireProtect 2 AC (Heat/Smoke/CO) Jeweller - White

The Ajax FireProtect 2 AC is a mains-powered, wireless fire detector that combines heat, smoke and carbon monoxide sensing in a single ceiling-mounted device. Built for the Ajax Jeweller radio ecosystem, it pairs with an Ajax hub to deliver fast, addressable fire alerts to a monitoring app or a professional monitoring station, while its built-in siren and backup battery keep occupants protected even during a mains power outage.

Key Features

• Triple-sensor protection: combines a dual-spectrum optical smoke sensor, two Class A1R thermistors for heat detection, and a dedicated carbon monoxide sensor in one housing.
• Mains-powered with battery backup: runs from 110-240V AC power and automatically switches to an internal sealed backup battery if mains power is lost.
• Self-cleaning smoke chamber: the sealed, dustproof and insect-resistant chamber is designed to resist contamination without regular manual cleaning.
• Smart false-alarm filtering: proprietary detection software analyses sensor patterns to tell real smoke apart from steam or dust, reducing nuisance alarms.
• Long-range wireless connectivity: communicates with the Ajax hub via the encrypted Jeweller protocol at ranges up to roughly 1,700 metres in open space.
• Interconnected alarm response: when one detector triggers, the hub activates every fire detector on-site within about 20 seconds, with a direct device-to-device fallback that still sounds all sirens within a minute if hub communication drops out.
• Loud on-device siren: an integrated 85 dB buzzer with distinct tone patterns for smoke, heat and CO alarms so occupants can quickly identify the type of threat.
• Quick, tidy installation: an improved SmartBracket mounting plate with WAGO 221 connectors and an optional CableTrunk accessory allow clean cable routing and installation in around 90 seconds without disassembling the unit.
• Professional monitoring compatible: events can be relayed through an Ajax hub to central monitoring stations using SurGard/Contact ID, SIA and similar protocols.

Ideal Applications

This detector suits homes, apartments and small commercial spaces where mains power is available at the ceiling, such as kitchens, living areas, hallways and plant rooms where fuel-burning appliances create a carbon monoxide risk. Because it integrates natively with the wider Ajax security ecosystem, it is well suited to installers building combined intrusion, fire and smart home systems on a single hub, and its interconnected alarm feature makes it particularly useful for multi-room residences where an early, whole-of-property warning is important.

Frequently Asked Questions

Does this detector need an Ajax hub to work?
It is designed to operate as part of an Ajax security system connected to a compatible Ajax hub, which enables interconnected alarms, app notifications and monitoring station reporting.

What happens if the power goes out?
The detector automatically switches to its internal backup battery, so smoke, heat and CO monitoring continues uninterrupted during a mains outage.

Can it detect carbon monoxide as well as fire?
Yes, it houses a dedicated CO sensor alongside its smoke and heat sensors, warning occupants before CO concentrations reach a dangerous level.
