Product Overview
Fidelity sound quality (SP2)
Enhanced SPL (SP3)
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:
1⁄4, 1⁄2, 1, and 2 watts. The SpectrAlert SP3 series offers greater sound output at
every tap setting for applications with high ambient noise levels.
25.0 and 70.7 Vrms dual voltage settings
Four field-selectable power taps
No extension ring required
Low profile design
Functionality. Installation ease and functionality are achieved via the speaker’s
compact design, which allows flush mounting to a 4˝×4˝×21⁄8˝ back box,
without the need for an extension ring.
Ceiling- and wall-mount applications
Grilles available in white and red
Color-matched mounting screws
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.
