Re: Minerva Mx-4000 False Fire Alerts btw 19:00 to 6:00

Sorry, I don't think most of us have experience with EN54 panels. We're mostly from an NFPA/UL or ULC background (US/Canada). Some concepts we have in common though. It sounds from your last test like it is related to loop field devices on loop D. It may be just one. I knew someone who traced a prob...

Re: Kidde Scorpio

I don't see why not. They are both conventional panels. But if you are doing this professionally, I recommend comparing the specs yourself or asking your company's engineers, rather than asking on a forum like this.

Re: Sync several 5495 boosters

Tech support may be confused. I can say with certainty that the SK-CONTROL does not provide any sort of sync signal, only switches the source 24 volts on and off. Yes, the 5495 NAC panel can do master or slave sync. In order to have it sync with other NAC panels, you need to use slave sync with the ...

Re: Pull stations should not be used as light switches.

Just please be careful. It's fun to play around with these things, and I've done it in the past. But if your house burns down, even for an unrelated reason, and they find evidence of DIY wiring that is not up to code, they can use it to deny all or part of your claim. They are ruthless like that and...

Re: Siemens Pyrotronics smb-2 ground fault

Clarification: does the ground fault stay active when the technician removed all the field wiring from the SMB-2? If so, you have a faulty board and it must be replaced and re-programmed. This can only be done by a Siemens dealer. Depending on if it was locked out by the original installer, you may ...

Re: Do fire departments have fire alarm systems?

Yes, they can catch on fire like any other building. Worked on one in a small town that was monitored by a central station. If there was ever a fire they would call the local dispatch, which was in that same building. Kind of silly, but that's what code called for.

Re: EST2 Dialers Keep Failing

DL2 dialers are that bad. You also may have gotten transient voltage from lightning on your phone lines if you have copper into the building. If you're lucky enough to find a new one that's been sitting on the shelf, that's probably your best bet. No component of the EST2 can be considered reliable ...

Re: FCI 7100 series piezo replacement

Sorry for the late reply, it is possible that this module will work in this situation. I sent you a PDF with some documentation, but Gamewell-FCI sent these piezo modules to distributors in 2008 for a recall with some boards manufactured in mid 2007 where the piezo did not work properly. According t...

Re: why do we have to do fire drills once a month

No, it's not just you, these rules don't apply to colleges and universities. NFPA 101 considers them a business or assembly occupancy, which have no fire drill requirements, unless the AHJ says otherwise. They are required in college dorms however, but it appears there is not a required frequency, j...

Re: Getting Asterisk / alarmreceiver to read DTMF digits properly.

You may be able to try listening in on the phone "conversation" and recording it to a wav file. This page has some suggestions for how to do that on the analog phone lines, or there may be way to do it within Asterisk. You could then analyze it with a program like Audacity to see if it is actually s...

Re: Why does the EST QuickStart get so much hate?

I don't like that the database of the EST panel can't be uploaded all . So it's hard to do things about old project . It is possible on the QuickStart. I have done it. Just not the EST2/EST3 and other brand variants like MIR2. QuickStart can also be programmed without need for a license key. But ye...

Re: Getting Asterisk / alarmreceiver to read DTMF digits properly.

This is a neat little project. I have yet to try it because I don't have the proper hardware, but it could potentially be useful in the field for troubleshooting dialer communications. I've also been thinking about a little open source coding project that would use a voice modem or sound card to "li...

Re: Fire Block Foam or Caulk

Yes, as EdwardsFan states, it must be rated and listed for the intended purpose. Never use general purpose caulking or insulation. There are many fire stop products available, be certain that the specifications meet what the building design requires and the F-rating meets or exceeds the fire rating ...

Re: Device mismatch on FCI and Silent Knight SLC

In my experience, Silent Knight panels will show a trouble when you have an FCI device connected to them. Not sure about the reverse though. Supposedly the 7100 actually works with any brand of device since it operates in CLIP mode and does not check the vendor ID. Haven't tried it though. Obviously...
