Skill: Mounting Accessories to Wall or Pier (e.g., Intercoms, Photobeams, Push Buttons)
Learning Objective
Learn how to securely mount accessories such as intercoms, safety photobeams, and push buttons to walls or piers at the correct position and height, ensuring functionality and long-term durability.
1. Overview
Mounting accessories is a key part of any gate installation. Getting the fixing right ensures both performance and longevity. Accessories must be level, stable, properly aligned and well sealed— especially photobeams, which are safety-critical.
2. Tools & Materials Required
- Drill (corded or cordless)
- Masonry drill bits (appropriate size)
- Screwdriver or impact driver
- Rawl plugs / wall plugs
- Stainless steel or weather-resistant screws
- Spirit level
- Tape measure
- Pencil/marker
- Silicone sealant (for weatherproofing)
- Mounting templates (if supplied)
- PPE: Safety glasses, gloves, ear protection
3. Pre-installation Steps
- Check the surface material – e.g., brick, block, render, metal post, or timber.
- Inspect the area for hidden cables or pipes before drilling.
- Mark up clearly using a pencil/marker and confirm level and symmetry.
4. Mounting Procedure
- Drill pilot holes to the correct depth.
- Insert wall plugs (if required).
- Align the accessory using a spirit level.
- Secure with screws, avoiding overtightening.
- Seal around screw holes or cable entry points to prevent water ingress.
- Test physical stability and, if applicable, preliminary function (e.g. beam alignment or button action).
- Clean the work area and ensure tidy cable routing (if visible).
- Seal around the outside with clear silicone
5. Best Practices
- Always use fixings suited to the surface.
- Photobeams should be mounted at ~400mm height unless otherwise specified.
- Intercoms and push buttons should be at a height suitable for pedestrians or drivers (covered in a separate lesson).
- Use sealant or grommets around cable entry to prevent water ingress.
- If unsure of structure strength (e.g., loose blocks), consider additional support or alternative fixing method.
6. Common Mistakes to Avoid
- Mounting too low or high (affects usability and safety).
- Misaligned beams — causes faults and unnecessary callouts.
- Loose fixings — accessories can come loose or fall over time.
Skipping sealing — leads to moisture ingress and premature failure.
