My middle school’s main alarms were the Edwards 892 series horn/strobes, but the main pulls were http://computek272.calvinet.com/alarmpics/ESLpull.JPG ESL 103-01 pulls. What’s even weirder is that on one side of the school, there is an ESL rebranded RSG Lift and Pull T-Bar installed, and, although it wasn’t directly underneath an 892, the pull and the signal weren’t too far away from each other.
I don’t know if this would be considered as a rare combo or just odd, but one of the science rooms (which had completed remodeling circa early 2006) at that same middle school had installed a SpectrAlert Classic with a BG-12 underneath it, near a back exit, but for some odd reason, an 892 horn/strobe was installed towards the main entry way in that same room.
At my high school there were 3 Siemens U-MMT-MCS horn/strobes installed in one hallway (which I have called it the “U-MMT hallway”), and 2 of them had Fire-Lite BG-10L’s underneath them, with Stopper IIs over them. Those U-MMT’s most likely replaced 7002T’s since those were the main alarms of that school (most likely from a major system overhaul done back around the mid to late 80’s since the high school was built in the mid 50’s). And in 2012, some of the 7002T’s were being replaced with EST Genesis horn/strobes w/ trim plates. One instance of this resulted in an EST Genesis horn/strobe mounted right above a BG-10L pull station, also with a stopper cover over it.
There’s more that I remember, but I’ll post about them at a later time.
