The SpectrAlert Advance Dual Strobe and Dual Strobe with Speaker Expander Plates is for emergency communications and mass notification systems.
The plates combine the functions of multiple devices on a single mounting plate and back box, lowering installation costs and improving aesthetics.
The expander plates include a UL 1638-listed (Visual Signaling Appliances) amber lens strobe for Private Mode General Utility Signaling. Several options for speaker strobes are available that can be wall- or ceiling-mounted.
