The casing uses the circuit board (2) itself as a cover. The circuit board is screwed to a holder (1) connected to the casing. The holder has studs (3) with holes to accept the self-tapping scrwes (4) that fix the board to it. The holder has a recess into which the edges of a U-shaped retaining rail (11) fits. The recess has overhangs (12) to hold the edges of the rail. The holder also has tags (9) with holes (10) to allow it to be fixed to a wall. The holder has ribs (8) for guiding connection wires leading to pins on the circuit board.
