Compatibility & Accessory Guidance

Most automatic light switch kits at Communica are compatible with standard South African 220-240V AC lighting circuits. Always confirm your lamp/fixture load rating and wiring method before purchase - for example:

• Relay rating: Match to the total wattage of all lights controlled (e.g. 2x 9W LED bulbs)
• Installation: Some kits are designed for surface box mounting, others for behind-wall panels; check enclosure options
• Manual override: Useful if you need to restore traditional switch functionality for maintenance/testing
• Accessory bundles: Ask for terminal blocks, cable, or enclosures when purchasing

Simple Application Example

If you install a PIR automatic switch in a corridor feeding two 10W LED fixtures (total 20W at 230V AC), select a kit with a relay rated minimally for 30-40W to ensure derating margin. Connect Neutral and Live per the included schematic:

L (Live In) ---------------o KIT o------------ L (Switched Live Out)
N (Neutral) ---------------o RELAY/KIT o------ N (to fixture)

Refer to the kit manual for specific layout - never exceed the specified relay rating.
