Product information

- Integrity’s rugged plastic housing is made durable and fire retardant, high impact plastic with a slightly textured surface. Housings are rated for outdoor use and are available in red or white. Integrity’s ingenious mounting plate firmly holds the device in place with a single screw. This ensures quick and attractive installation. A separate trim plate is not required. Speaker terminals accept up to #12 AWG (2.5mm²) wire for polarized connections. Strobe connections are made to color-coded wire leads.

- Life safety strobes are shipped with standard wall mount style FIRE lens markings. Where ceiling orientation, 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. Consult Kidde for availability of special lens markings.

- Integrity 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.

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.

• Listed 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.

• 98 dBA Output

- High efficency driver produces a loud 98 dBA at 15 watts.

• Multiple Output Taps, 25 or 70 Volt Models

- Easy to for 2, 4, 8, and 15 watt operation. Integrity speakers are supplied with a DC Blocking Capacitor for audio circuit supervision.

• Outdoor rated

- Durable red or white Noryl front plate is ideal for outdoor, industrial or harsh environments.

• Field changeable field markings

- Lens language or standard “FIRE” marking is easily changed with optional LKW (wall orientation) and LKC (ceiling orientation) lens kits.



- All Integrity speakers include a DC blocking capacitor to allow electrical supervision of the audio distribution circuit. Models for 25 VRMS and 70 VRMS circuits are available. Wattage taps 2 W to 15 W provide on-site flexibility.

- The suggested sound pressure level for each signaling zone used with alert or alarm signals is a minimum of 15 dB above the average ambient sound level or 5 dB above the maximum sound level having a duration of at least 60 seconds, whichever is greater. This is measured 5 feet (1.5 m) above the floor

- Doubling the distance the signal to the ear will theoretically cause a 6dB reduction in the received sound pressure level. The actual effect depends on the acoustic properties of materials in the space. Doubling the power output of a device (e.g.: a speaker 1W to 2W) will increase the sound pressure level by 3dBA

Re-entrant Speaker and Speaker-Strobe INT Series


- Kidde clear strobes are UL 1971-listed for use indoors as wall- or ceiling- mounted public-mode 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, INT Series strobes exceed UL synchronization requirements (within10 milli-seconds over a two-hour period) when used with a synchronization source. Synchronization is important in order to avoid epileptic sensitivity.

- Integrity strobes are fully compatible with Kidde Genesis signals.

Installation and Mounting

All models fit to flush mounted Kidde box, Catalog Number 960A-4SF. Optional flush trims are not required. For surface mount, use Kidde’s custom indoor and outdoor surface boxes painted in color-matched red or white epoxy. Kidde recommends that these Life safety and ECS/MNS speaker/strobes always be installed in accordance with the latest recognized edition of national and local codes.
