Central de alarma de incendios Ajax 60834.176.WH1 blanca 1700 m de alcance 85 dB

The Ajax 60834.176.WH1 is a white wired fire alarm detector designed for integration into residential and commercial alarm systems. With a maximum wireless range of 1700 m to the central hub in optimal conditions and a built-in siren rated at 85 dB (measured at 3 meters), the device provides audible alerting and multi‑mode notification. The compact central unit measures 122 x 122 x 54 mm and the detector is powered from an external AC supply of 110–240 V at 50/60 Hz, with an internal backup battery for continued operation during mains interruptions.

Advantages

The detector uses a double‑spectrum optical sensor that detects smoke by particle size, while a patented smoke chamber shields the sensing element from dust, dirt and insects to reduce contamination and extend service life. The sensor design reduces false alarms by ignoring water vapor and conforms to Class A1R heat detector sensitivity requirements, meeting EN 54‑5 and BS 5446‑2 standards. Interconnected alarm logic supports both hub‑initiated and direct fallback interconnection to ensure that all detectors sound reliably even if communication with the hub is lost. Clear LED status indication and a front‑panel button for testing and muting provide straightforward local control.

Suitable for

• Apartments and private homes
• Small offices and commercial premises
• Multi‑detector installations requiring interconnected alarms
• Locations where immunity to steam and dust protection is important

Key specifications

• Sensing: double‑spectrum optical smoke sensor (particle‑size detection)
• False alarm protection: insensitive to water vapor
• Compliance: sensitivity class A1R; meets EN 54‑5 and BS 5446‑2 requirements
• Built‑in siren: 85 dB at 3 m
• Interconnection: hub‑initiated interconnected alarm; direct fallback interconnection between detectors
• LED indicators: green (power), yellow (malfunction), red (alarm)
• Power supply: external 110–240 V~, 50/60 Hz with internal backup battery
• Physical: compact central unit dimensions 122 x 122 x 54 mm; central unit weight 318 g
• Mounting: SmartBracket with WAGO terminals for external power connection

How to use

Install the detector on the SmartBracket mounting plate and connect the external power using the WAGO terminals without the need to disconnect cables when removing the detector. Configure the device in the Ajax hub and mobile app to enable two‑way communication, monitoring and remote configuration. In normal operation, press the front button to run a smoke chamber test; in case of alarm or malfunction press the same button to silence the detector sound notification. The hub propagates an alarm to other system devices within 20 seconds, while fallback interconnection ensures direct detector‑to‑detector alerts if hub communication fails.

Recommendations

Place detectors on ceilings or high on walls following local fire safety guidelines, avoiding locations close to cooking appliances or steam sources despite the detector’s resistance to water vapor. Regularly inspect and clean the smoke chamber as indicated by the malfunction LED, and check the backup battery and wiring periodically. Test the detector using the front‑panel test function after installation and during routine maintenance to ensure reliable operation.
