SAFEPATH DoD Facility Communications System


SP40S-D - Supervised Voice Evacuation System

Designed for Department of Defense (DoD) facilities, Eaton's SAFEPATH (SP40S-D) is an Emergency Voice Evacuation System with 24 VDC battery backup. The multi-use system can function as an evacuation, emergency messaging, paging, personnel alerting, and background music delivery system. The SP40S-D integrates with fire alarm systems and provides full control of building audible and visual notification appliances.

To meet the UFC requirement for automatic alarm audible shutoff after 10 minutes, the SP40S-D includes a 10-minute time-out feature, which automatically deactivates Fire and Emergency digital voice (DV) messages inputs 1 - 6 after 10 minutes. Alarm DV messages inputs 7 and 8 do not automatically time out.
