116 Class Fire Alarm Strobe Lights for Use in 
Hazardous Locations Installation Sheet 
Description
The 116 Class Fire Alarm Strobe Lights, available in either a 
gray housing (116DEGEX-FJ) or a red housing (116DEGEX-
FJ-R) are in-rush current limited strobe lights. When 
pendant, wall or ceiling mounted, and with dome guard 
removed, they meet or exceed the requirements of UL 1971 
Signaling Appliance for the Hearing Impaired. 
The strobe is intended for indoor use in UL 1971 (signal 
appliance for the hearing impaired) listed compatible fire 
alarm systems. The strobe flashes a 360-degree beam of 
light approximately 65 times per minute with a UL 1971 
125 cd ceiling and 60 cd wall light output per Figure 7 and 
Figure 8. With the guard installed, the strobe flashes a 
beam with an output of 86 cd ceiling and 51 cd wall. The 
strobe is also UL 1638 (visual signal appliance, private 
mode) listed with dome guard installed for both indoor and 
outdoor use, and other applications requiring electrical 
supervision of the signaling circuit field wiring. In addition, 
the strobe is rated for outdoor use in Canada. The 116 
Class strobes are cUL listed to Canandian Standard ULC-
S526-07 (Visual Signal Device for Fire Alarm Systems), 
suitable for indoor and outdoor applications. The strobe 
features an enhanced synchronization circuit to comply with 
the latest requirements of UL 1971 and CAN/ULC-S526-07. 
Synchronized operation requires a separately installed 
synchronization control module. See Table 1 on page 5 for 
a list of compatible synchronization modules. 
When assembled with an available mounting subassembly 
(116EX(R)-P, 116EX(R)-C, or 116EX(R)-C with 116EX(R)-B) 
and in accordance with these instructions, the 116 Class
