System Sensor’s SP2 and SP3 series speakers combine performance, functional-
ity, and flexibility in the latest line of dual-voltage evacuation speakers.
Performance.
With its low total harmonic distortion, the SpectrAlert SP2 series
offers fidelity-quality sound output. This performance provides greater assur-
ances that the SP2’s output more closely matches the source signal. This fidelity
sound quality is achieved at any of the SP2’s four field selectable power taps:

, 1, and 2 watts. The SpectrAlert SP3 series offers greater sound output at
every tap setting for applications with high ambient noise levels.
Functionality.
Installation ease and functionality are achieved via the speaker’s
compact design, which allows flush mounting to a 4˝×4˝×2

without the need for an extension ring.
Flexibility.
The SP2 and SP3 series speakers are designed for a variety of applica-
tion requirements. Offered with round and square grilles, they can be ceiling
or wall mounted. White and red grille color options are also available to meet
specific aesthetic requirements.
