The SS‑SRK Strobe, one of the System Sensor
SpectrAlert Advance notification appliances, simplifies
installations with features such as plug‑in designs,
instant feedback messages to ensure correct
installation of individual devices, and field‑selectable
candela settings. This strobe is designed for outdoor
wall‑mounted applications.
SpectrAlert products can be used in either DC or
full‑wave rectified (FWR) systems (12 V or 24 V). If
required, the SSMDL module can be used to provide
synchronization.
Notice
Full‑wave Rectified (FWR) voltage is a
non‑regulated, time‑varying power source that is
used on some power supply and panel outputs.
Notice
SpectrAlert products set at 15 cd and 15/75 cd
automatically work on either 12 V or 24 V power
supplies. The products are not listed for 12 V
operating voltages when set to any other candela
settings.
Functions
Strobe
When wired as a primary‑signaling notification
appliance, the strobe complies with the Americans
with Disabilities Act (ADA) requirements for visible
signaling appliances, flashing at 1 Hz over the strobe's
entire operating voltage range. The strobe light
consists of a xenon flash tube and associated lens and
reflector system.
For 24 V applications, the total number of strobes on a
single NAC must not exceed 40, with a maximum loop
resistance of 120 Ω. For 12 V applications, the total
number of strobes must not exceed 12, with a
maximum loop resistance of 30 Ω.
