901 Series emergency phones are ADA compliant like our 401 Series and share the same application uses. One of the main distinctions is that these phones are AC powered and come equipped with a back-up battery which ensures 4+ hours of talk time in the case of a power failure. They include two hot keys, one for quick location message recording and the other for dial-out phone number programming. 901 Series phones can share a single incoming phone-line and are compatible with our line loss monitoring system. COP Mount, Flush Mount, Surface Mount, Cabinet Mount and Outdoor models are available, as well as optional weather protection.
