Gamewell-FCI ATD-L3-IV is a Velociti Series 3 intelligent thermal detector in ivory with 135 °F fixed-temperature detection. It is the service model for legacy installations and operates in both Velociti and CLIP protocols for backward compatibility.
The detector reports its measured temperature continuously to the fire alarm control panel and has point ID capability, with the address set on rotary switches. The E3 Series and S3 Series panels support both protocols; the GWF-7075 supports Velociti only.

FAQ
Is a base included?
No. Bases are ordered separately, for example the B501-IV flangeless or B300-6-IV flanged base, or relay, isolator and sounder bases.
Will it work on a CLIP panel?
Yes. The -IV service models operate in both Velociti and CLIP protocols. The bright white ATD-L3 is Velociti only.
What temperature does it alarm at?
The ATD-L3 offers 135 °F fixed thermal detection. The ATD-L3R adds rate-of-rise and the ATD-L3H alarms at 190 °F.
How is it tested?
It has a built-in functional test switch that is activated by an external magnet, such as the M02-04-01 or M02-09-00.
