Needs checking

Confirm the exact hub for FireProtect 2 AC (Heat/Smoke/CO) Jeweller; family names do not identify a supported pair.

What else needs checking?

The model's general minimum is OS Malevich 2.18; identify the exact hub because host-specific limits can be higher.

Confirm the regional equipment version for LV; a country name alone does not identify the radio version.

Sensors: smoke, heat, co. Requires 110–240 V AC, 50/60 Hz at each detector position. The backup battery does not replace its normal mains supply. Indoor use at 0°C to +50°C and up to 80% humidity. Confirm placement and alarm audibility separately; this is not an EN54 system selection.

Fallback fire interconnection. Requires compatible FireProtect 2 device firmware 5.59.2.XX or later, OS Malevich 2.19+ for hub configuration, and an enabled, tested peer network. Basic hub pairing does not confirm this feature.

Look closer at smoke detection.

A protected optical chamber

The smoke chamber directs air past the optical sensor while its design limits interference from dust and insects. Keep the exterior clean and follow the manual; do not open the smoke chamber for routine cleaning.

Detect a high temperature or a sudden rise.

Two thermistors positioned outside the enclosure

Two A1R-class thermistors

Two thermistors monitor temperature outside the enclosure. The detector raises a heat alarm above +64 °C or when temperature rises by more than 10 °C within one minute.

These alarm conditions apply to the European model. Choose the sensor combination and installation position for the room; heat detection does not replace required smoke coverage.

Monitor carbon monoxide as well as exposure time.

Carbon monoxide alarm illustration; the depicted cloud visualises an invisible gas

A dedicated chemical CO sensor

The sensor responds to accumulated carbon monoxide exposure. Ajax specifies an alarm within 90 minutes at 50 ppm, 40 minutes at 100 ppm and 3 minutes at 300 ppm. The CO sensor has a 10-year service life.

This is a carbon monoxide alarm, not a detector for methane or other fuel gases. It does not replace proper installation and maintenance of fuel-burning appliances.

Mains power. Backup when the supply stops.

Mains wiring, mounting and backup-power demonstration

110–240 V AC with a built-in reserve

The detector uses 110–240 V AC at 50/60 Hz, with mains consumption up to 2 W. A built-in CR-2/3AZ lithium battery provides backup when the external supply is interrupted. The app shows external-power and backup-battery status when a hub is connected.

The backup battery is non-replaceable. Replace the detector when that battery is depleted or at the end of its 10-year service life. Battery Life Optimization must be enabled; backup endurance depends on use and conditions.

A local alarm, with a clear device status.

85 dB sound and LED indications

The built-in siren is rated at 85 dB at 3 m. Sound patterns and LEDs distinguish an alarm from a fault, low battery or end of life. With a compatible connected hub, configured app notifications identify the detector and its room.

The detector monitors its own sensors even when the intrusion system is disarmed. As a standalone detector it provides local warnings; app notifications and remote settings require a hub.

One detector can warn the others.

Alarm passed to fire detectors through the hub

Primary alarm through the hub

An enabled detector sends its alarm to the compatible Ajax hub, which activates the other fire detectors within 20 seconds. System capacity depends on the hub, connected devices and configuration.

Alarm passed directly between fire detectors

A direct path between detectors

Compatible FireProtect 2 detectors can propagate the alarm directly within 60 seconds, including when the hub connection is lost. This fallback path runs alongside primary interconnection.

Requires supported detector hardware and firmware 5.59.2-series or later, the enabled fallback setting and a successful coverage test. With a hub, use OS Malevich 2.19 or later; Hub (4G) requires 2.28 or later.

A local network without a hub

Supported detectors can be paired into a standalone alarm network of up to 50 units. Follow the exact pairing instructions and test coverage. This arrangement provides local sound and LED warnings; it does not send Ajax app notifications without a hub.

Keep the radio path connected.

Jeweller two-way communication

Jeweller carries alarms and device states using encrypted communication, device authentication, frequency hopping and automatic power adjustment. Check the model’s specified open-space range and measure signal strength in its installed position.

Plan coverage through the building

A compatible ReX or ReX 2 can extend the Jeweller link to the hub. ReX 2 can also use Ethernet for its hub connection. Hub capacity and exact device compatibility apply; verify signal at each detector and test fallback coverage separately.

Walls, floors and interference reduce radio range. The building illustration explains a connection method, not a guaranteed coverage area.

Check the hub before installation.

Exact model and firmware matter

These AC detectors require a supported Ajax hub with OS Malevich 2.18 or later. Hub (4G) requires 2.28 or later. Fallback interconnection has the additional conditions described above. Confirm the radio region and exact compatibility list before pairing.

See the alarm and its source.

Device, room and event history

With a connected hub, Ajax app notifications identify the detector and room. The event log records the time and event type. Configured PRO Desktop or monitoring-station integration adds an operator view; monitoring service and response arrangements are separate.

Add context to an alarm.

Photos from a separate detector

A compatible MotionCam (PhOD) can take photos after a configured FireProtect 2 alarm. A suitable hub, photo permissions and the scenario must be set up beforehand. FireProtect 2 AC has no built-in camera.

Separate automation devices can support a professionally planned response involving suitable circuits or door hardware. Scenarios do not replace the required alarm response.

A neat route for surface wiring.

CableTrunk joining surface trunking to the detector mounting panel

CableTrunk, where the cable comes from the side

The optional CableTrunk accessory joins surface cable trunking to FireProtect 2 AC. It provides a dedicated route to the mounting panel while keeping the ceiling finish tidy.

CableTrunk is a separate accessory. Electrical work and cable routing must be included in the installation plan.

Wire, pair and check the installation.

SmartBracket with WAGO 221 connectors

A qualified installer connects the mains supply using the two pre-installed WAGO 221 terminals in SmartBracket, fixes the panel and aligns the detector. Choose the mounting position and clearances from this model’s manual.

Indoor use only: 0 to +50 °C and up to 80% humidity. Electrical work is planned and quoted separately. A room photograph is an application example, not a placement rule.

Test it. Respond to service warnings.

Using the front panel to test the detector

Test/Mute on the front panel

Press the centre of the front panel to start the detector self-test as described in the manual. App testing is available with a connected compatible hub. Check the sound and light indications after commissioning and follow the regular testing schedule.

Wait at least 3 minutes after switching the detector on before testing. Local requirements may call for more frequent checks.

Plan for the detector’s service life

Respond to fault, low backup-battery and end-of-life warnings. The detector has a 10-year service life and must also be replaced if its non-replaceable backup battery is depleted. Do not treat a renewed mains connection as a battery replacement.

Treat a CO alarm as an alarm.

Silencing is not an all-clear

Use remote silencing only while in the line of sight of the CO detector. The alarm cannot be muted when the CO level exceeds 300 ppm. Silencing the sound does not remove the hazard; follow the emergency instructions in the manual and your local response procedure.

Additional features

Built-in siren: volume 85 dB at a distance of 3 meters Sound notification of alarms. Remains active until the reason for triggering is eliminated or until the user manually disables the notification.
Interconnected fire detectors alarms: via primary interconnection If one of the fire detectors in the system detects a threat, it sends an alarm to the hub. Within 20 seconds, the hub initiates an interconnected alarm and sends data to Ajax apps. via fallback interconnection At the same time with notifying the hub, the initiating detector sends an alarm directly to other detectors. All connected detectors activate the buzzer within a minute. It will work even in the worst-case scenario of losing connection with the hub.
LED indication: green is a power indication An LED indicator on the device enclosure lights continuously when powered by an external power source. If the device draws power from the backup battery, the LED indicator lights up once every 56 seconds. This indication complies with the requirements stipulated in EN 14604 and EN 50291 standards. yellow is a malfunction indication An LED indicator on the device enclosure lights up to signal detected malfunctions. This can occur in instances such as battery depletion, smoke chamber contamination, or reaching the end of the service life. red is a fire alarm indication An LED indicator on the device enclosure lights up when the detector registers a fire alarm.
