Re: Simplex 4010 testing

The best way to do this is to run a silent walk test. This will allow you to test the flow switches without going into full alarm, and you can configure the walk test so that the signals do not sound: Notify monitoring, just in case the dialer dials out. Tell them to put the system on test. Log in t...

Re: HTTP error when adding pics in posts

Attachments have always been a spotty feature on TFP, and I used to recommend imgur to host images. Unfortunately, imgur is transitioning itself away from being an image hosting service to being yet another social network, and they had an issue with some related posts being NSFW. I like the way imgu...

Re: End of electromechanical horns

I'd say around the time Siemens stopped manufacturing their own signals around 2008 or so. They seemed to be the last bastion for new electromechanical horns for fire alarm systems. The U-HN-MCS was one of the last electromechanical alarms ever made. Simplex had switched to the TrueAlert around the ...

Re: Simplex 4006 Level 4 Password Help

I’ve got a simplex 4004 in our building. No trouble codes and unit resets like normal HOWEVER the trouble signal screw ( terminal 8) is hot (24vdc). Tried to post my own thread several days ago but it’s stuck in waiting for moderator approval. Apologies for that - we had two accounts register relat...

Re: NAC 1 fried on my firelite ms 9200 ud

In normal condition, if you were to meter the terminals (red probe on B+, black probe on B-), you should receive a reading of -24v because NACs are supervised by means of reversed polarity. In alarm condition, that should swap to a positive 24v. There could very well be a fuse blown on the NAC, in w...

Re: Silver pull stations.

According to RSG, they do still manufacture white pull stations with red lettering, but, It also has to be approved by the Fire Marshall in that particular jurisdiction. (that was directly from the email reply I got from Helen at RSG). I imagine then, that they're a custom deal, and that's why they ...

I can’t remember the model numbers of the light plate and the Adaptahorn, but I believe the pull station...

Re: Silver pull stations.

NFPA 72 doesn't actually forbid the use of white or silver pull stations. 17.15.5 Manually actuated alarm-initiating devices shall be mounted on a background of contrasting color. [...] 17.15.9.3* Unless installed in an environment that precludes the use of red paint or red plastic, manual fire alar...

Re: scammers on youtube channels like ser saftey

It appears to be a YouTube-wide security breach, and it's not just on Grant's channel (mine has been hit with these spambots too). The consensus from other bigger YouTube news channels that have covered this issue is do not interact with them. If they ask to be friends, even replying to them with "n...

Re: NAC 1 fried on my firelite ms 9200 ud

Just a few questions:

Are you getting a NAC trouble at all on the 9200? What signal are you using, and do you have it wired as Class A or Class B?

Re: Voices of fire alarm systems

The one I'm trying to get a positive ID on is the one who does (or did) the Simplex messages. At first, he sounded a bit like John Doyle, a professional voiceover artist who did voices for the Audichron company for telephone company recordings, and also shortwave radio stations like WWV . So, with t...

Re: fire alarm testing

I'm assuming you're located in the UK? From what I can gather, testing procedure seems to be something like this: 1. Call your monitoring company and inform them that you're going to do your weekly test 2. Test a different call point each week - find the call point you want to test 3. Activate and t...

Re: I'm not dead -- here's what I've been up to!

Vintage telephony is something I’ve gotten interested in too. It started with stumbling upon Evan Doorbell’s tapes on YouTube, and I eventually got to meet the guy over coffee. He’s lived in San Antonio since the 90s and still makes narrated phone tapes today.
