Dependable Emergency Communications

The Simplex 4003EC Small Voice Panel is an advanced emergency voice/alarm communications panel that can serve as a multi-function voice control panel for single building applications or operate as a part of a facility-wide Emergency Communications or Mass Notification system. Supporting remote placement of amplifiers totaling up to 5,000 watts, the 4003EC can replace local messaging with centralized messaging, a key Emergency Communications requirement. The 4003EC can be used to easily add voice messaging capability to facilities already using a non-audio fire alarm system. It can also be installed along with non-audio control units to bring voice announcements to smaller new construction projects. The 4003EC also supports up to 18 microphones for live broadcasting and the recording of custom alerts and safety messages right at the panel.
