New low proﬁ le design
Screw terminal capacity up to AWG #12
Field selectable taps from ¼ Watt – 2 Watts
25V RMS or 70.7V RMS models
Mounts to 4” square back box

Amseco’s low proﬁ le, high quality, ﬁ re alarm speakers are designed to reproduce attention penetrating tones and voice commands for emergency signaling evacuation systems. These highly efﬁ cient low proﬁ le speakers are available with ﬁ eld selectable taps from ¼ W – 2 Watts. They are available in two input voltage models 25V RMS and 70.7V RMS and can be installed on a standard 4” x 4” x 1 ½” electrical back box without the need of an extension ring for a fast and cost effective installation. An in-line capacitor provides the isolation necessary for supervisory use.
The round and square speaker series are available in red or white housing.
The FH-47 Series speakers are designed to meet UL 1480 requirements for audible and voice communications. The low proﬁ le FH-47 speakers produce a broad frequency range to reproduce emergency signals and voice communication.
