8.5.2 Test Lamp
Due to the advanced discrimination of the FL4000H, the TL105 Test Lamp was
developed. The Test Lamp is a battery operated, rechargeable, test source specifically
designed to test General Monitors’ IR Flame Detection Systems. It consists of a high-
energy broadband radiation source that emits sufficient energy in the infrared spectra
to activate the IR detector. To simulate a fire, the TL105 Test Lamp automatically
flashes a signal that the FL4000H recognizes. The lamp must be set to rotary switch
position “4” to be recognized by the FL4000H. See Appendix A for details.
Operating Instructions
The FL4000H has the ability to be put into a special test mode activated state by
momentarily grounding the test mode pin on the unit or by issuing a Modbus write
command to register 0x5A. The unit will respond by going into this test mode activated
state and by blinking a unique flashing pattern with the green LED on for 0.9 seconds
and off for 0.1 seconds. The analog current output will respond by outputting 1.5 mA
(3.5 mA with HART and small HART current disabled). While the FL4000H is activated
in test mode via the Test Lamp, the FL4000H will detect the TL105 Test Lamp as a
flame source. The analog output and relays will respond as if a flame were present.
The analog output will rise from 1.5 mA (3.5 mA with HART and small HART current
disabled) to 16 mA (warning condition) and then to 20 mA (alarm). Relays will trip. In
addition, an alternating red/green LED blink pattern is displayed. By momentarily
grounding the test mode pin a second time, or by re-issuing a Modbus write command
to register 0x5A, or after a 3-minute time out, the unit will return to normal operation in
the Ready state.
NOTE
: The TL105 Test Lamp triggers the FL4000H into test mode, causing an alarm
condition.
It is important to begin a series of flame detector checks with a fully charged Test
Lamp. Stand between 10 and 35 feet from the FL4000H that is to be tested and aim
the Test Lamp directly into the detector window. Press the ON button and be sure the
high intensity pulsing beam strikes the detector face squarely. Hold the Test Lamp as
steady as possible.
To conserve charge, do not operate the Test Lamp longer than is necessary to test
each channel.
When the battery level drops below the level required to maintain the proper intensity
of the lamp, an internal low voltage circuit will shut the lamp off until the battery has
been recharged. Please refer to the TL105 Test Lamp manual for complete operating
instructions.
