* RMS current ratings are per UL average RMS method. UL max current
rating is the maximum RMS current within the listed voltage range (16-33v
for 24v units). For strobes the UL max current is usually at the minimum
listed voltage (16v for 24v units). For audibles the max current is usually
at the maximum listed voltage (33v for 24v units). For unfiltered FWR
ratings, see installation instructions.

NOTE: All CAUTIONS and WARNINGS are identified by the symbol . All warnings are printed in bold capital letters.
WARNING: PLEASE READ THESE SPECIFICATIONS AND ASSOCIATED INSTALLATION INSTRUCTIONS CAREFULLY BEFORE USING, SPECIFYING OR
APPLYING THIS PRODUCT. VISIT WWW.COOPERWHEELOCK.COM OR CONTACT COOPER WHEELOCK FOR THE CURRENT INSTALLATION INSTRUCTIONS.
FAILURE TO COMPLY WITH ANY OF THESE INSTRUCTIONS, CAUTIONS OR WARNINGS COULD RESULT IN IMPROPER APPLICATION, INSTALLATION AND/OR
OPERATION OF THESE PRODUCTS IN AN EMERGENCY SITUATION, WHICH COULD RESULT IN PROPERTY DAMAGE, AND SERIOUS INJURY OR DEATH TO YOU
AND/OR OTHERS.
General Notes:
•
Strobes are designed to flash at 1 flash per second minimum over their “Regulated Voltage Range”. Note that NFPA-72 specifies a flash rate of 1
to 2 flashes per second and ADA Guidelines specify a flash rate of 1 to 3 flashes per second.
•
All candela ratings represent minimum effective Strobe intensity based on UL Standard 1971.
•
Series NS Strobe products are listed under UL Standard 1971 for indoor use with a temperature range of 32°F to 120°F (0°C to 49°C) and
maximum humidity of 93% (± 2%).
•
Series NH horns are listed under UL Standard 464 for audible signal appliances (Indoor use only).
•
“Regulated Voltage Range” is the newest terminology used by UL to identify the voltage range. Prior to this change UL used the
terminology “Listed Voltage Range”.
