Fixed temperature heat detector Ei Electronics Ei630W Wireless Surface-mounted

The Ei Electronics Ei630W Wireless Surface-mounted fixed temperature heat detector is a compact device intended for reliable heat detection in domestic and light-commercial environments. Designed for surface mounting, the detector responds when ambient temperature reaches a predefined threshold. Its wireless design enables integration into compatible alarm or monitoring systems while running on a 3V lithium battery. The unit's 12 cm diameter and 56.3 mm depth provide a low-profile presence on ceilings or walls, and the 190 g weight simplifies handling during installation.

Advantages

The Ei630W offers fixed temperature sensing for clear, threshold-based detection of sustained heat increases rather than smoke, which is useful in environments prone to false alarms from combustion particles. Wireless connectivity simplifies placement where wiring is impractical and supports integration with compatible systems. Battery operation ensures continued function during power outages and reduces the need for mains wiring. The surface-mounted form factor enables installation on a variety of ceiling and wall types with minimal structural impact.

Suitable for

• Residential kitchens, boiler rooms, garages and utility spaces where heat, not smoke, is the primary hazard
• Light-commercial premises such as offices, small workshops and storage rooms
• Retrofit projects where wireless devices avoid the need for new cabling
• Locations requiring surface-mounted detectors due to ceiling or structure constraints

Key specifications

• Detection type: fixed temperature heat detection
• Power supply: 3V lithium battery
• Mounting style: surface-mounted for ceiling or wall installation
• Dimensions: 12 cm diameter, 56.3 mm depth
• Weight: 190 g
• Connectivity: wireless for integration with compatible alarm systems

How to use

Mount the Ei630W on a suitable flat section of ceiling or high on a wall following the manufacturer's recommended location guidelines for heat detectors. Remove protective packaging, insert the specified 3V lithium battery if not pre-installed, and secure the detector using the included fixings. After installation, allow the device to join the intended wireless network or alarm system according to the system's pairing procedure and perform any required system tests to confirm communication and correct functioning. Regular testing according to local safety standards is recommended to ensure ongoing operation.

Usage recommendations

Install the detector away from direct sources of heat such as ovens, boilers or radiators to avoid nuisance activation; instead position it where heat from an incipient fire would accumulate. Replace the battery as specified by the manufacturer and follow periodic testing and maintenance schedules. Use the detector as part of a wider detection and alarm layout to ensure comprehensive coverage.
