The SP-Series 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.
They 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.
