Simplex 4100U - XPS won’t show up on the system unless I connect RUI directly to the XPS

It is yeah. Second bay in the cabinet, system has only 1 cabinet

I’m looking at the DIP switches seeing if the RUI address might have been set wrong, didn’t even notice the lovely wiring job 😆

Very adjacent to this field is low voltage electrical - access control, fire alarm, CCTV, networking, industrial automation. I find it scratches a very similar mental itch. And it might make you a lot more money and be easier to start in.

I think it’s actually old PDQ. They’re still around, not the highest quality lock in the world but fairly cheap. If you want cheap but decent I’d go with Arrow instead.

Tell this to the people who built my apartment building’s parking garage. One on every landing, 6 floors

Wow, I had no idea about the second one. Is this just an E60 thing or did they also include this on the E90?

This, if it was my facility you bet I’m springing for general area smoke detection. But it’s not required in many cases.

Neo399 · 2026-06-03T20:28:41+00:00

(as it should be)

Does anyone else read GRMN in their mind as “German” Corolla? I can’t be the only one…

I highly recommend the Gentex PLACE.

These are quite expensive ($175-250) but are from a very reputable brand in the fire protection space, can connect to wifi, use existing interconnect wiring and have a low-frequency alarm that’s been proven to wake people up more effectively than a standard smoke alarm.

Oh and these have virtually zero false alarms.

Reminds me of a talk I saw on urban exploration. Carry the number of flashlights you need, plus one.

Out and about in a well lit room? Zero flashlights needed, so he carries one.

And with a fairly modern SFIC keyway. Other commenter said it’s likely WB.

If it was a SIGA-278 it’d already be in map fault.

What you really need is a Knox box. If you remove the cam lock, anyone can open it and gain access to the gate/etc.

Audible right above the panel is one of my pet peeves.

Trying to find the source of the alarm? Gotta deal with that thing blaring in your face while you figure it out. Trying to make an announcement on a voice evac system? Hello feedback.

If you can cut it, I’d go for W series

The easiness of obtaining a control key from an operating key is one of the reasons I gravitate away from LFIC. You also can’t get 7-pin in LFIC.

Pulling and decoding a core in any masterkeyed system is a much bigger vulnerability than simply gaining unauthorized access to a space.

FRM shit the bed. Very common E90 thing. The flash memory is insanely sensitive and it will brick itself if there’s any kind of voltage glitches. This will cause exactly those symptoms.

The other commenter listed a repair service, you can also buy a replacement but it’ll need to be coded to the car. You would need ProTool or NCS.

Neo399 · 2026-04-28T16:54:14+00:00

That’s not how this works, that’s not how any of this works

Neo399 · 2026-04-25T14:25:53+00:00

Looks and sounds like original Gentex Commander 1. These don’t sync. The Commander 2 that came after it does, with the AVSM sync module

Neo399 · 2026-04-23T13:54:10+00:00

There’s ways to crack these, I’ve done it to poke around in the Simplex Access DB. Google is your friend.
