Analog Door Box Analog Door Box Installing the Analog Door Box Do not connect an Analog Door Box to a digital station port. The Analog Door Box (P/N 92245) is a self-contained Intercom unit typically used to monitor an entrance door. A visitor at the door can press the Analog Door Box call button (like a door bell). The Door Box then sends chime tones to all extensions programmed to receive chimes. To answer the chime, the called extension user just lifts the handset. This lets the extension user talk to the visitor at the Door Box. You can connect up to 2 Analog Door Boxes to your system. The base system provides an Analog Door Box and associated relay at extension 324. If you have the Expansion Board installed, you have a second Analog Door Box and associated relay at extension 325. Analog Door Boxes do not add to the System Load Factor. Each Analog Door Box also has an associated control relay. You can use this relay to release an electric strike on the entrance door. After answering the Door Box chimes, the extension user can press FLASH or a soft key to enable the Analog Door Box's relay, which in turn unlocks the door. The Analog Door Box is a weather-tight unit, with an operating temperature range of -20 to 60 degrees C (-4 to 140 degrees F) and a relative humidity of 10-95%, non-condensing. !! Important !!
