Ajax FireProtect 2 AC (Heat/Smoke) Jeweller in White

FAQs

What is the FireProtect 2 AC (Heat/Smoke) Jeweller and what does it detect?

The FireProtect 2 AC (Heat/Smoke) Jeweller is a wireless mains-powered fire detector designed for indoor installation. It detects both smoke and temperature rise using a bispectral optical sensor for smoke detection and two built-in class A1R thermistors for heat detection. The detector operates as part of the Ajax system and communicates via the secure Jeweller radio protocol.

How is the detector powered and what happens during a power outage?

The detector is powered by 110-240 V~, 50/60 Hz mains power and includes a sealed backup battery. Even during a power outage, the detector continues to operate from the backup battery. With the Battery Life Optimization feature enabled, the backup battery can last up to 10 years, ensuring continuous fire protection throughout the detector’s lifespan.

What is the coverage area of one FireProtect 2 AC detector?

The coverage area of one FireProtect 2 AC (Heat/Smoke) detector is 50 to 60 m², depending on the type of premises. The detector should be installed in every room, placed in the center of the ceiling at a distance of 30 cm from light fixtures, chandeliers, or other decorative objects that may interfere with alarm detection.

How does the interconnected fire alarm system work?

All FireProtect 2 AC detectors in the system can synchronously notify about fire alarms through two methods: primary and fallback interconnection. When danger is detected, the initiating detector sends an alarm to the hub, which activates all fire detectors’ sirens within 20 seconds (primary interconnect). Meanwhile, the initiating detector also directly sends the alarm to other detectors (fallback interconnect). Even if connection with the hub is lost, the interconnected fire alarm takes only about a minute to activate.

Can the detector work without being connected to an Ajax hub?

Yes, FireProtect 2 detectors can operate autonomously without connecting to an Ajax hub. In autonomous mode, the detector notifies of fire or smoke using only its built-in siren and LED indication. However, users won’t receive notifications on Ajax apps, Ajax Translator, or PRO Desktop when operating in this mode.

What are the temperature thresholds that trigger heat alarms?

The detector triggers heat alarms under two conditions: it reports that the temperature threshold has been exceeded when the temperature reaches +64°C, and it reports a rapid temperature rise if the temperature increases by 10°C within one minute. If the temperature rises sharply by 20°C or more, the detector alerts immediately.

How do I test the detector to ensure it’s working properly?

You can test the detector in two ways: by pressing and holding the Test/Mute button on the center of the front panel for 1.5 seconds, or through the Ajax app by going to the detector settings and selecting “Self-test.” During testing, the red LED flashes 5 times and the siren activates. Wait at least 3 minutes after turning on the detector before running a self-test. If the detector is in alarm state, the self-test is not available.

What do the different LED colors and patterns indicate?

The detector uses three LED colors for different indications: Red LED indicates alarms (continuous flashing during fire, different patterns for muted alarms and restoration); Yellow LED indicates malfunctions, low battery, or tamper alerts; Green LED shows power status (constantly on when external power is connected, flashing once per minute when on backup battery) and connection status with the hub.

How often should I test the detector and what maintenance is required?

It’s recommended to test FireProtect 2 devices periodically (monthly) to familiarize building residents with the fire alarm signals. However, local regulations might require more frequent testing (e.g., weekly). The detector has a self-test system and doesn’t require user intervention. Clean the enclosure of dust and cobwebs as needed using a soft dry cloth, but avoid using alcohol, acetone, gasoline, or other active solvents.

Where should I install the detector and where should I avoid installing it?

Install the detector in the center of the ceiling, 30 cm away from light fixtures and decorative objects, in every room. Avoid installing outdoors, in places with low signal strength, areas with rapid temperature changes (bathrooms, near heaters), corners, very dusty areas, near fans or vents, or in rooms where smoke/vapor generation is part of normal operations (like garages). The detector is designed for indoor installation only.

What should I do when the fire alarm sounds?

Never ignore the alarm! Always assume it’s real and evacuate immediately. Don’t open doors if you feel heat or smoke behind them – find alternative exits. If heavy smoke enters a room, stay close to the floor and crawl out, breathing through wet cloth if possible. Close doors behind you when leaving, evacuate quickly without packing belongings, arrange a meeting place outside, ensure everyone has evacuated safely, and call the fire department immediately.

How long does the detector last and when should it be replaced?

The service life of the detector is 10 years. After this period, the sensitivity of the sensors decreases, so it’s recommended to replace the detector with a new one to ensure uninterrupted fire protection. The detector must also be replaced when the backup battery is completely discharged, as the battery is sealed and non-replaceable.
