Since 1968, Nylube Products Company, LLC. has been supplying the elevator industry with a complete line of emergency lights to satisfy the requirements of Rule 204.7a, ANSI A17.1, Safety Code for Elevators and Escalators. The features of our product support a simple and reliable installation:
CHARACTERISTICS OF A PROPERLY FUNCTIONING EMERGENCY LIGHT
Our patented circuit which includes several features not found in other elevator emergency lights, automatically recharges the nickel-cadmium battery. To insure a correctly installed, properly functioning unit:
1. Depress the test button (disconnects power) to make sure unit is working. Both lamps should light up.
2. When the battery is fully charged, the filament in the lamps acts as a load resistor to keep the battery from overcharging. An indication of this is a small glowing light in the bulb. Even though the filament is glowing, the lamp is not really "on". This does not affect bulb life.
TROUBLESHOOTING
BATTERY/CHARGING MODULE: The rechargeable battery has an expected service life of 10 years and should be replaced after that time. To check for a defective battery, perform the following test:
1. Press the test button. If no lights come on, check to make sure the lamps are not burned out.
2. Test the alarm bell with and without line power by pressing the station button.
3. If lamps do not light and bell does not ring (without line power), the battery is probably dead, or it may also indicate that the charging module is defective.
LAMPS: If one lamp burns out and the remaining lamp goes to full bright, replace both lamps. Lamps should only be replaced with the correct Nylube replacement lamp. Use of other lamps voids the warranty.
FUSE: If a fuse blows, it is usually an indication of a short. Locate and repair the short, then replace fuse.
For problems not addressed by suggestions above, the unit should then be sent to Nylube factory for repair. (See Service Information Bulletin #12)
