Hekatron handbedieningsknop HAT 155 F AP opbouw handbedieningsknop IP20

The Hekatron Handauslösetaster HAT 155 F AP surface-mounted manual release button IP20 is a compact, wall-mounted actuator designed for manual triggering of safety and alarm systems in indoor environments. With an IP20-rated enclosure, this manual release button provides a clearly defined control point for initiating emergency release or alarm functions where protection against solid objects is required but splash or water resistance is not necessary. The device is intended for fixed mounting on flat surfaces and integrates with building safety circuits to allow rapid manual intervention.

Advantages

The HAT 155 F AP offers a simple operating principle and a compact design that minimises space requirements on mounting surfaces. Its surface-mounted format simplifies installation in retrofit situations and in locations where in-wall recessing is impractical. The IP20 rating ensures protection against contact with fingers and similar objects, making it suitable for indoor installation in controlled environments. The actuator provides reliable tactile feedback to confirm manual activation and is compatible with common safety and alarm control wiring practices.

Suitable for

• Manual triggering of fire alarm systems and emergency release mechanisms in indoor premises
• Surface-mounted installations on walls in offices, corridors, and utility rooms
• Retrofit upgrades where flush mounting is not possible
• Integration into building safety circuits requiring a clearly labelled manual release point

Key specifications

• Mounting type: surface-mounted
• Protection class: IP20 (protection against solid objects larger than 12 mm)

How to use

Mount the Hekatron HAT 155 F AP on a flat, accessible wall surface at a height and position compliant with local safety and accessibility regulations. Connect the device to the building's safety or alarm control circuit following the wiring diagrams provided by the central control equipment and local electrical standards. Label the unit clearly so users can identify its function. To operate, press the button firmly to initiate the manual release or alarm signal; the unit will provide tactile confirmation of activation. After use, reset or replace components as required by the connected control system and maintenance procedures.

Recommendations

Use this surface-mounted manual release button only in indoor locations where IP20 protection is sufficient. Ensure regular functional testing as part of the building's safety maintenance program and verify wiring compatibility with the central alarm or release equipment before installation.
