Synchronized Strobe MS-7A
MS Series ⭐
✅ strobes are specially designed for use with compatible life safety communication and control equipment to alert the hearing impaired of a life safety event. Strobes are available with 15/75 cd, and 110 cd effective flash intensity. They are fully compatible with Genesis signals
- Strobes are shipped with standard wall mount style “FIRE” lens markings. Where ceiling mount, other languages, or different lens markings are required, Kidde offers optional LKW and LKC series Lens Marking Kits. These optional lens markings simply snap on to the strobe.
- MS Series strobes are designed for 16 to 33 Vdc operation and must be connected to signal circuits that output a constant (not pulsed) voltage. A diode is used to allow full signal circuit supervision and polarized connections are made to terminals that accept up to #12 AWG (2.5mm²) wire.
- The strobe housing/front plate is finished in red or white and is made durable and fire retardant, high impact plastic with a slightly textured surface.
Standard Features
• UL 1971-listed synchronizing strobe
- Integrity strobes synchronize to the latest UL 1971 requirements when used with a synchronization source.
• Genesis-compatible
- All Genesis and Integrity strobes on the same circuit meet UL 1971 synchronization requirements when used with an external control module.
• Approved for public and private mode applications
- UL 1971-listed as signaling devices for the hearing impaired and UL 1638-listed as protective visual signaling appliances.
• Rated for wall or ceiling installation
• Field changeable field markings
- Lens language or standard “FIRE” marking is easily changed with optional LKW and LKC series lens kits.
• Screw terminal wire connection
- Large terminals speed installation and accept up to #12 AWG (2.5mm²) wire.
• Fits one-gang flush box
- Ideal for retrofit and renovation projects. Optional colormatched surface boxes available.
Application
- Strobes are UL 1971-listed for use indoors as wall-mounted publicmode notification appliances for the hearing impaired. Prevailing 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, MS Series strobes exceed UL synchronization requirements (within 10 milliseconds other over a two-hour period) when used with a synchronization source. Synchronization is important in order to avoid epileptic sensitivity.
