System Sensor’s SpectrAlert Dual Strobe notification appliance is designed to
accommodate unique signaling applications where two stage notification is required.
Flexibility.
The SpectrAlert Dual Strobe line incorporates two visible notification
appliances, to accommodate those applications where a two stage alarm system
or two distinct visible signals are required. Available in white or red housings
and a variety of colored lens options, SpectrAlert Dual Strobes allow a user to
customize visible notification for both fire and non-fire applications including
pre-action alarms, security, tornado alert, evacuation, etc.
Performance.
Based upon the principles of the original SpectrAlert wall mount
strobes, the Dual Strobe models operate at 24 volts, and provide 75 candela out-
put per UL 1638. The strobes may either be powered in tandem over a two wire
circuit or independently over a four wire circuit.
Installation.
Like all SpectrAlerts, the Dual Strobes offer installation ease and
flexibility. These models are typically mounted to a single gang back box.
Using the mounting bracket provided, four square back box mounting is also
accommodated.
Customization.
SpectrAlert Dual Strobes provide the flexibility to customize the
product in the field. If desired, the strobe modules can be field-reversed, for left
or right-mounting of each colored strobe. Multiple labeling options are provid-
ed, including FIRE, ALERT, EVAC and EVACUATE, to designate the
specific function for each strobe.
