Gamewell-FCI ATD-L3 — Velociti Series 3 intelligent thermal detector with a 135 °F fixed temperature alarm point, in bright white, on the Velociti protocol.
A single thermistor monitors the temperature and reports it to the control panel, so the head gives a reading and a point address, not just a contact closure. This is the fixed temperature member of the family with no rate of rise function; that is the one-character sibling ATD-L3R. The test switch is operated with a magnet rather than by applying heat.
- 135 °F fixed temperature detection, no rate of rise element
- Complies with UL 268 7th Edition; UL S2332, FM 3023594
- 15 to 32 VDC; 200 µA standby at 24 VDC, 2 mA maximum alarm current
- -4 to 100 °F (-20 to 38 °C), 10 to 93 percent RH
- 2.0 in. high, 6.1 in. across in a B300-6 base and 4 in. in a B501
The siblings differ in one respect each: ATD-L3R adds rate of rise, ATD-L3H is the 190 °F high temperature version, and ATD-L3-IV is the ivory service model running Velociti or CLIP where this bright white head is Velociti only. Bases are separate numbers, B501 flangeless or B300-6 flanged.

FAQ
Which panels support the ATD-L3?
It runs the Velociti protocol. E3 Series and S3 Series panels support Velociti and CLIP, and the GWF-7075 supports Velociti only.
Is a base included?
No. Bases are ordered separately: B501-WHITE 4 in. flangeless, B300-6 6 in. flanged, or the relay, isolator and sounder bases.
What if my system uses CLIP only?
Use the ivory service model ATD-L3-IV, which operates on both Velociti and CLIP.
How is it tested?
With an external magnet, which activates the built-in functional test switch.
