Gamewell-FCI ATD-L3H — Velociti Series 3 intelligent thermal detector with a fixed high-temperature alarm point of 190 °F, in the bright white housing.
A 135 °F head is a nuisance in spaces meant to run hot, so the ATD-L3H lifts the fixed alarm point to 190 °F and lifts the permitted ambient with it. It is a single-thermistor detector that reports measured temperature continuously to the panel rather than simply closing a contact, so the panel holds point identification.
- Fixed high-temperature alarm point of 190 °F (88 °C)
- Operating ambient -4 to 135 °F (-20 to 57 °C), 10 to 93% humidity
- 15 to 32 VDC; 200 µA standby, 2 mA maximum alarm current
- Rotary decimal address switches, 01 through 159
- Dual LEDs for 360 ° visibility; magnet-operated test switch
- UL S2332, FM 3023594, MEA-FDNY 219-02-E, CSFM 7270-1703-0502
ATD-L3 is the 135 °F fixed head and ATD-L3R adds rate of rise at that same point; both share this housing and the Velociti protocol. ATD-L3H-IV is the ivory service version of this same 190 °F detector, and ivory models also run CLIP for legacy panels. Bases are ordered separately.

FAQ
Is a base included?
No. The data sheet lists bases separately: B501 4 in. or B300-6 6 in. mounting bases, plus relay, isolator and sounder bases.
Which panels and protocol does it use?
The bright white ATD-L3H runs the Velociti protocol. E3 Series and S3 Series panels support Velociti and CLIP, and the GWF-7075 supports Velociti only. The ivory ATD-L3H-IV service model runs both Velociti and CLIP.
What ambient temperature can it be installed in?
The 190 °F model is rated for -4 °F to 135 °F (-20 °C to 57 °C).
How does it differ from the ATD-L3 and ATD-L3R?
The ATD-L3 is a 135 °F fixed detector and the ATD-L3R adds rate-of-rise at 135 °F. The ATD-L3H alarms at a fixed 190 °F.
