Speakers are designed for broadcasting high quality tone signals and are ideal for alarm signaling in hotels, malls, apartments and other areas where attractive appearance and dependable performance are prime concerns. These speakers consist of a loudspeaker, 6 oz. magnet, a low profile constant voltage
line matching transformer; a D.C. blocking capacitor and an all steel speaker baffle finished
in an off white color.
The 25 and 70 volt transformers are of the matching type and include output power
taps of ¼, ½, 1 and 2 watt(s). Tap selection is made by wiring into the appropriate slot
on the speaker’s terminal block. The SP-Series speakers install easily using the surface or
flush back boxes.
