Amplified Speakers are designed to produce crisp, clear tones in supervised alarm notification systems. These amplified speakers can broadcast tones generated by a tone card installed into the speaker (the plug‑in 32‑tone UTM*) or by a central tone source in a voice evacuation or paging system. When live public address or voice messages are required, plug‑in Connector Cards (AM25CK or AM70CK) interface with the Vrms of the EVAC panel.
Both amplified speakers are compatible with fire alarm and suppression supervised control panels and power boosters.
The rugged construction and high output of these speakers make it ideal for use in harsh environments with high ambient noise levels. Both models feature an internal gain control for adjustment to the suit area.
ULC Fire Listed Models (‑CN models) can only be used with a UTM tone card
