LED Steady On and Flashing in One
The 500L is generally referred to as a Campus Blue Light, or Call Box Light, or Telephone Wall Box light. This unique signal light is capable of steady burning when power is applied to it (12-24 Volts AC or 12-24 Volts DC operation), and when that power is also switched to its third input wire, the light begins to flash at one of 21 different rates of flash. This operation is common for applications that need to have a "steady on" light for identification of a safe point, or emergency call box location, and then also have the capability of providing a flashing light when the phone ( in the case of an emergency call box) is being utilized during an emergency--this allows security personnel to help identify the location of the call box in use, etc. Other applications are limited only by the imagination....
The 500L design takes full advantage of LED lighting technology to eliminate
maintenance, and reduce power consumption in these emergency system
applications. The 500L features an integral inverted cone design to provide full
360 degree coverage with a very low profile. The LED illumination design allows
more of the LED light to be projected out than do conventional fixtures.
Manufactured to NEMA 4X specifications. It is available in five colors
(amber, blue, green, red, purple, and clear--select above-all units us a white light
The 500L is highly energy efficient, and the solid state design will operate efficiently for many years.
The 500L is guaranteed against factory defects for a full 5 years.

To activate the unit in the PRIMARY - STEADYBURN MODE, connect the BLACK
wire to -Vdc and connect the RED wire to +Vdc . When in PRIMARY - STEADYBURN
MODE, to change the unit to the SECONDARY - FLASH MODE,
connect the white wire to +Vdc.
PROGRAMMING PRIMARY & SECONDARY MODES:
1) Remove power from unit.
2) Connect the White wire and Red wire together.
3) Restore power to the unit and wait approximately 3 seconds until the unit
flashes 3 times. Remove the white wire only from +Vdc, the unit will alternately
demonstrate the Secondary - Flash Mode and Primary - Steadyburn Mode that will
be displayed during operation. The Secondary ©\ Flash Mode, followed by the
Primary - Steadyburn Mode will be alternately demonstrated for approximately 4
seconds each. To select the next mode of operation, tap the white wire to +Vdc.
The unit will cycle to the next mode in the list below.
4) When you reach the desired mode of operation, remove power from the unit.
When power is reapplied the unit will operate as last programmed.
