Test Lamps
Some manufacturers claim that their detectors do not need remote testing with an external Test Lamp
because it tests itself. Even though Honeywell Analytics Detectors also perform "through the lens" self-testing
and tests themselves, Honeywell Analytics, in compliance with NFPA 72 codes, has developed portable test
lamps for periodical "end-to-end" testing their Detectors remotely. Some of the most important functions of
the remote test lamp are to ensure the Detector's optical path is not blocked, the Detector is aimed properly at
the fire threat area (that the Detector mounting bracket didn't move or was accidentally bumped by someone),
and the Detectors alarming circuitry and outputs (i.e. relays, 4-to-20 mA, open collectors, etc.) function
properly. Internal Detector testing and window lens cleanliness testing cannot insure the Detector is aimed
properly, that its view of the fire scene has not been blocked by something such as a newly installed pipe or
duct, storage box, parked vehicle, etc., and its alarm outputs are functioning properly.
For calibrated testing, in compliance with NFPA 72 Codes for flame detectors, as manufacturers of the FSX
product line, our calibrated testing using our FT-2055X Test Lamp is as follows. If the FS19X/FS20X set at
Highest Sensitivity alarms to a fully charged FT-2055X Test Lamp at a distance between 1 and 25 feet, then
the FS19X/FS20X is in normal operating condition.
WARNING: Use test lamp model TL1055s in non-hazardous locations only! For
hazardous locations, use models TL2055 or TL2145, as described below.
TL1055X is a general purpose NEMA 1 hand held
rechargeable Test Lamp designed for testing the
FSX™ Detectors externally.
Lamp (see Figure 4-1) comes with a Universal
Charger (110 VAC and 220 VAC).

Field of View Restrictor
There are some unique and specialized applications that may require a restricted field of view in order to
prevent the Detector from alarming to a known (friendly) fire/flame source (such as a flare stack). The Model
FVR-01 Field-of-View Restrictor is easily modified in the field with a simple hack saw to obtain custom
Detector field-of-views for applications where specific narrow field-of-views are required. The Model FVR-01
Detector accessory has been developed specifically for these unique types of applications.
