Lamp
Due to the advanced discrimination of the FL4000, 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,
TL105 Test Lamp automatically flashes a signal that the FL4000 recognizes. The lamp must be
set to rotary switch position “4” to be recognized by the FL4000. See Appendix A for details.
Operating Instructions
The FL4000 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). While the FL4000 is
activated in test mode via the Test Lamp, the FL4000 will detect 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) 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 FL4000 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 FL4000 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. Shaking the lamp from side to side or up and down will
increase the simulation of flame flicker, and improve the response of the flame detector to the
lamp.
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.
