The BRACKET C set of wall brackets is designed for mounting the outdoor detectors: OPAL, OPAL Plus, OPAL Pro and AOD-200. The set consists of two types: ball-joint bracket and angle bracket. The ball-joint bracket offers the swiveling vertical range of 60° and the horizontal swiveling range of 90°. This makes it easier to find the optimal position relative to the detection zone. However, if the premises require that the detector be set permanently at an angle of 45° relative to the wall, you can use the angle bracket. Each of the brackets is also provided with a tamper switch responding to any attempt to pull the device away from the wall.
