Control Box, main, houses 13 relay boards, for 1816/1820


The Model 1816 telephone intercom system provides communication to, and control of, a door (or gate) for up to 1200 users without the need for a dedicated Central Office (C.O.) phone line. This eliminates monthly line charges and equipment lease payments to the telephone company. The system is used widely with housing authority projects and low income housing because the system will provide all building residents, whether they have central office phone service or not, with communication and control of the door or gate.
