Pro Intercom AD950 Active Telephone Line Connection to Intercom Interface

The Pro AD950 is a cost - effective and straightforward device that connects your intercom system to a standard telephone line. Similar to a beltpack, it connects to the intercom system via a 3 - pin XLR on the rear panel. There's also a second XLR for looping to the next station in the circuit. Key features include: using a standard modular telephone cable for the phone line connection; no auto - answer function; when the red LED flashes for an incoming call, moving the hook switch from On to Off answers the call and links it to the intercom; the rear second modular jack lets you connect a simple DTMF - keypad telephone to initiate calls from the AD950; powered by the intercom system, no batteries or separate power supply needed, and the front - panel green LED shows it's powered.

Using the Pro AD950 is easy. First, connect it to your intercom system using the 3 - pin XLR on the rear panel. Then, use a standard modular telephone cable to connect it to the telephone line. If you want to initiate calls, connect a simple telephone with a DTMF keypad to the second modular jack on the rear. When the red LED flashes, it means there's an incoming call. Just move the hook switch from On to Off to answer it and connect it to the intercom system. Note that this device doesn't have an auto - answer feature. As for maintenance, since it's powered by the intercom system, make sure the intercom system is working properly. Keep an eye on the front - panel green LED; if it's not lit, there might be a power issue. And that's all you need to know to use your Pro AD950 effectively.
