SPEAKERS
System Sensor offers a wide range of power settings for your life safety needs,
including ¼, ½, 1, and 2W.
Sound levels data per UL 1480 can be found in Table 1.

Signal levels exceeding 130% rated signal voltage can damage the speaker.
Consequently, an incorrect tap connection may cause speaker damage. This
means that if a 25V tap is selected when a 70.7V amplifier is being used,
speaker damage may result. Therefore, be sure to select the proper taps for the
amplifier voltage/input power level combination being used.
