Voice alarm
Voice alarm loudspeakers are specifically designed for use in applications, where the performance of PA systems is subject to official regulations. The LA1- UM20E-1 and LA1-UM40E-1 are designed for voice alarm systems.
Protection
Both loudspeaker columns have built‑in protection to ensure that in the event of a fire damage does not cause failure of the connected circuit. In this way, system integrity is maintained; ensuring loudspeakers in other areas can still be used to inform people of the situation.
Connections and safety
The loudspeaker columns have a ceramic terminal block, thermal fuse, and heat-resistant, high temperature wiring. The column has a provision for internally mounting the optional line/loudspeaker supervision board.
Loudspeaker output power setting
Four primary taps are provided on the built‑in matching transformer. Loudspeaker output power setting is done on the build-in transformer and connected to a rotary vary‑tap switch located in the back of the enclosure to allow simple output power setting. An 8 ohms setting is also provided on the rotary vary‑tap switch.
