Installation and Maintenance Instructions
DO NOT TOUCH LAMP WITH BARE HANDS—Oil deposits
on the glass portion of the strobe lamp can cause the
glass to fracture during use. If you are unsure if the glass
has been handled without gloves, clean the glass using a
soft cloth and isopropyl alcohol before installing the lamp.
To replace the flash tube:
1. Disconnect the power to the beacon and wait at least 5
minutes to allow all capacitors to discharge.
2. Remove the threaded dome assembly by twisting it
counterclockwise.
3. With the dome removed, gently pull the flash tube from its
socket. A rocking motion is most helpful when installing or
removing the tube.
4. Replace the flash tube. Ensure that the replacement tube is
fully seated in the socket.
5. Replace the globe assembly. Ensure that the globe
assembly is seated securely against the gasket.
6. Test the light for proper operation.
