Dual Strobe Expander Plates
System Sensor’s SpectrAlert Advance Dual Strobe and Dual Strobe with Speaker Expander Plates for emergency communications system (ECS) and mass notification system (MNS) applications enable installers to combine the functions of two to three devices onto a single mounting plate and back box, lowering the overall cost of the installation and requiring fewer devices on the wall. The expander plates include a UL 1638-listed (visual signaling appliances) amber lens strobe for Private Mode General Utility Signaling that meets DOD specification requirements. They can be used in 12- or 24-volt systems and can be paired with a fire-rated SpectrAlert Advance strobe or speaker strobe. Along with the expander plates, System Sensor is releasing three outdoor speaker strobes to enable customers to meet a wider range of ECS and MNS requirements.
