Angle Anchor Plate Hekatron THM413/433/439/440 AFS 55 – mounting plate for smoke/heat detectors

Angle Anchor Plate Hekatron THM413/433/439/440 AFS 55 is a mounting plate designed to secure compatible Hekatron smoke and heat detectors at wall-to-ceiling junctions. The plate creates a stable angled interface that allows detectors from the THM413, THM433, THM439 and THM440 series to be installed where a direct ceiling or wall mount would not achieve optimal sensor orientation. The accessory is intended for both residential and commercial environments where precise detector positioning and reliable mechanical attachment are required.

Advantages

The plate provides a firm mechanical connection between the detector base and building surfaces, reducing movement and maintaining correct detector alignment. Its angled design simplifies installations at corners and transitions, enabling consistent sensor placement without complex on-site modifications. The accessory is compatible with multiple detector series, which helps standardize mounting components across different installation points.

Suitable for

• Mounting Hekatron smoke and heat detectors at wall-to-ceiling junctions
• Installations requiring an angled detector orientation for improved coverage
• Residential apartments, offices, corridors and stairwells
• Retrofit projects where existing wiring and conduit require an offset mount

Key specifications

• Compatible detector series: THM413, THM433, THM439, THM440
• Function: angled mounting plate for wall-to-ceiling junctions
• Material: durable mounting-grade material suitable for interior installations
• Mounting method: mechanical plate for secure attachment of detector base
• Application environment: residential and commercial indoor use

How to use

Position the angle anchor plate at the intended wall-to-ceiling junction and mark the fixing points according to the detector base. Secure the plate to the building substrate using appropriate screws and anchors for the wall material. Attach the compatible Hekatron detector base to the plate, ensuring correct alignment and firm engagement. Connect detector wiring following applicable electrical and safety standards, then mount the detector housing onto its base and verify secure fit and correct orientation.

Recommendations

Use fasteners and anchors appropriate for the substrate (drywall, concrete, brick or timber) and follow local installation codes. After installation, verify detector operation and field of view according to Hekatron installation instructions; perform functional tests and routine maintenance as required.
