Fitting tips

Isolate the power supply before fitting or changing any access control part, and keep low voltage cables away from mains cables. Test the door, the release and the exit device several times after fitting. Doors on escape routes must always let people out safely, so check with your fire risk assessor or a qualified installer. For electrical safety advice, see Electrical Safety First.

How a simple access control system works

A basic door access control system has four parts. A lock, such as a maglock or electric strike, holds the door shut. A keypad, card reader or key switch lets authorised people in. A press to exit button or touchless sensor lets people out, and a green break glass unit overrides everything in an emergency. A 12V power supply runs the whole system and sets how long the door stays unlocked. Because every part is standard, you can start small and add to it later – for example adding a keypad to a key switch system. This access control power supply is one part of that system, so check the other parts are in place before you install.
