• Manufacturer Part Number: CS405-7A-T
• Description: 20H4968
• Manufacturer: EDWARDS SIGNALING PRODUCTS

Application
Edwards strobes are UL 1971-listed for use indoors as wall-mounted
public-mode notification appliances for the hearing impaired. Prevail-
ing codes require strobes to be used where ambient noise conditions
exceed specified levels, where occupants use hearing protection,
and in areas of public accommodation. Consult with your Authority
Having Jurisdiction for details.
As part of the Enhanced Integrity line of products, CS405 Se-
ries strobes exceed UL synchronization requirements (within 10
milliseconds other over a two-hour period) when used with a
synchronization source. Synchronization is important because a
small portion of the population have a condition which may cause
them to become disoriented from multiple random flashes of light.
Integrity strobes minimize this risk.
Integrity strobes are fully compatible with Edwards Genesis sig-
nals.

rated for current in RMS values. Most of these devices operate based upon
the heating affect of the current flowing through the device. The RMS current
determines the heating affect and therefore, the trip and hold threshold for those
devices.

Installation and Mounting
All models fit to a standard flush mounted, North American four
inch electrical box, 1-1/2 inch (38 mm) deep minimum. Optional
Edwards weatherproof, surface mount boxes are available. The
strobes must be connected to signal circuits which output a
constant (not pulsed) voltage. Edwards recommends that these
strobes always be installed in accordance with the latest recog-
nized edition of national and local fire alarm codes.
NOTE: The flash intensity of some visible signals may not be adequate
to alert or waken occupants in the protected area. Research indicates
that the intensity of strobe needed to awaken 90% of sleeping persons
is approximately 100 cd. Edwards recommends that strobes in sleeping
rooms be rated at at least 110 cd.
WARNING: These devices will not operate without electrical power. As
fires frequently cause power interruptions, further safeguards such as
backup power supplies may be required.
