STROBE LIGHT OUTPUT FOR WALL & CEILING

MOUNTING

The intensity of the strobe light gradually lessens as the angle increases. In other words, the light is brightest directly in front of the strobe light and is progressively less bright to either side. As required by Underwriters Laboratories Inc. (UL), the following illustrations show how the strobe light is dispersed. Use them to help you choose where to locate units for the hearing impaired.

PHOTOSENSITIVE EPILEPSY AND STROBE FLASH RATES

Individuals who are susceptible to photosensitive epilepsy might have an increased probability for seizures with multiple strobe lights flashing asynchronously. The frequency or speed of flashing light that is most likely to cause seizures varies from person to person. Generally, flashing lights most likely to trigger seizures are between the frequency of 5 to 30 flashes per second (Hertz). This strobe light flashes at about 1 flash per second.

Under the Americans with Disabilities Act, most workplaces and places serving the public, including theaters, restaurants, and recreation areas, are required to have fire alarms, which flash as well as ring so that people who cannot hear or cannot hear well will know that there is an emergency.

WEEKLY TESTING

To test this strobe light you must activate the test button of each inter- connected, smoke, CO or heat alarm. This will send a signal to the strobe light and cause the unit to begin flashing. Depending on what type of alarms you have connected, the strobe light will flash different patterns.

Smoke/Heat Alarms: Constant approximately 1 flash per second.

CO Alarms: Intermittent approximately 1 flash per second for four flashes, then 5 seconds off. Pattern is repeated.

These different patterns are to help a hearing impaired person better distinguish the danger present. The flash patterns approximate the audible alarm emitted by either a smoke or heat alarm or a carbon monoxide alarm. Note that a heat alarm will emit the same horn pattern as a smoke alarm. Make sure all members of your family understand the different flash patterns.

Do not look directly at or touch the lens while the strobe light is flashing. Doing so can hurt your eyes or burn your fingers. If the strobe light does not flash during testing and the alarm does not sound, check the fuse or circuit breaker supplying power to the alarm circuit. If the alarm sounds and the strobe light does not flash, refer to the installation instructions in this manual to insure strobe light is wired properly. If the strobe light still does not work it should be replaced.

When testing the interconnected alarm, do not stand too close to the unit when the alarm is sounding. It is loud to wake you in an emergency. Exposure to the horn at close range may harm your hearing. All interconnected alarms connected to this strobe light must be tested individually to ensure proper connections. It is important to test all interconnected alarms every week to make sure they are working properly. Using the test button is the recommended way to test the alarms and strobe light.

HOW TO INSTALL THIS STROBE LIGHT

This Strobe Light is designed to be mounted on any standard wiring junction box to a 4-inch (10 cm) diagonal size, on either the ceiling or wall (if allowed by local codes). Read “Recommended Placement for Hearing Impaired Strobe Lights” before you begin installation.

Tools you will need: • Standard Flathead screwdriver • Wire strippers

THE PARTS OF THIS STROBE LIGHT

The Mounting Bracket

Installs onto the junction box.

It has a variety of screw slots to fit most boxes. If a junction box is not already in place, install one using standard #12 or #14 gauge copper wire.

To remove the mounting bracket from the base, hold the base firmly and twist mounting bracket counterclockwise.

The Power Connector

The power connector plugs into a power input block on the Strobe Light and supplies it AC power.

•Black wire is “hot.” •White wire is neutral.

•Orange wire is used for interconnect.

If you need to remove the power connector, turn POWER OFF first. To remove the power connector, insert a flat screwdriver blade between the power connector and the security tab inside the power input block. Gently pry back the tab and pull the connector free.

Make sure the Alarm is not receiving excessively noisy power. Examples of noisy power could be major appliances on the same circuit, power from a generator or solar power, light dimmer on the same circuit or mounted near fluorescent lighting. Excessively noisy power may cause damage to your Alarm.
