Description
The CTI SL3-24-GYR-B is a 24V AC/DC StackLight 3 stack light with 3 LED light modules (green, yellow and red) and a built-in 105 dB buzzer. It gives personnel at-a-glance visual and audible alarm status from a gas detection system.
CTI notes that differentiated colors give a clear indication of the severity of a leak situation. The green module is steady (non-flashing); the other colors flash at 84 flashes per minute.

Common questions
Can the light modules be rearranged or added to later?
Yes. CTI ships configurations pre-assembled, and the light modules are easily interchanged to change their order. Individual light, buzzer and base modules are sold as StackLight 3 components, up to 6 light modules per stack.
Will these modules work on the other voltage base?
CTI states the light modules and buzzer are interchangeable between the 24V AC/DC and 120 VAC bases. This SL3-24-GYR-B is built on the 24V AC/DC base module.
Specifications are based on the CTI (Calibration Technologies) product page for Stacklight 3 - 24v. Confirm fit, ratings and application requirements before ordering.
