The Detector Base B501AP is designed to accommodate intelligent fire detectors Series 200-Advanced, 200 and 500. The sophisticated design of the base permits easy mounting, and the large cable entry allows unhindered cabling. Due to its robust multi-wire screw terminals, the detector base can be wired with ease, thus achieving a secure and durable connection. The reliable contact with the detector is ensured by particularly high-quality contact springs. Thanks to an additional terminal, the base is compatible with Detectors Series 200-Advanced with integrated isolator. Furthermore, a terminal for connection of a remote indicator is provided. The mechanical theft protection of the detector can optionally be activated. An integrated plastic plate allows easy labelling of the detector without additional accessory. For this purpose, the label plate is broken off from the base and is attached to the base from below. The Detector Base B501AP is designed for surface mounting in dry rooms. In case of surface mounted cabling, cables with a diameter of up to 8mm can be inserted. For flush mounting as well as for use in moist rooms or false ceilings, a range of accessories is available. White and cream-coloured versions of the Detector Base B501AP are available.
