I have an opportunity to interface asterisk with a security system to open their magnetic door locks. The security system needs a dry contact close upon activation to signal the door. Has anyone done this before?

I think you can buy some kind of ATA's to do such a job. I do not however remember any brand names Google returned these links: http://www.voip-info.org/wiki/view/Asterisk+phone+door&view_comment_id=15775 http://www.abptech.com/products/its.html Mobotix c james wrote:> I have an opportunity to interface asterisk with a security system to > open their magnetic door locks.

Hi James I did it some years ago to open an electric door entry. I used an home-made board with embedded tcp-ip stack and a perl AGI scripts that sends some UDP packets containing a "secret" passphrase. The AGI it's still triggered by an internal extension call. I think that today you can find some reasonable price ethernet DIN rail industrial controls that provides HTTP capabilities and you can write a simple AGI script that generates some HTTP transactions to set the board rele' status to whatever you want. Best regards, Marco Signorini. c james wrote:> I have an opportunity to interface asterisk with a security system to > open their magnetic door locks.

Has anyone done this before?Worst case, Ciarcia's Circuit Cellar magazine has an ad this month for a TCP to RS-232 box for something like 69 bucks; you could probably use the RTS line to drive a relay.

However, I found this recently: Low voltage: http://www.cleware.de/p-usbswitch35-E.html Mains: http://www.cleware.de/p-usbswitch-E.html Linux command-line control, so can be "called" from a System or AGI from the dialplan without any issues.

How about something like this? http://www.pencomdesign.com/1ch_relay.htm No personal experience with that board, but it looks sensibly designed and should be very easy to code for. -Keith ----- Original Message ----- From: "c james" <cjames at callone.net> To: <asterisk-users at lists.digium.com> Sent: Thursday, July 17, 2008 5:43 AM Subject: [asterisk-users] Magnetic door locks>I have an opportunity to interface asterisk with a security system to > open their magnetic door locks.

One of the last "secure" facilities I worked in had a motion sensor that unlocked the door for people leaving from one door. The COO was pretty shocked when I took off my belt, easily pushed it through the gap in the glass doors near the top and triggered the motion sensor, immediately opening the door to the admin side of the building. The other side did not have motion sensor just an RFID and magnetic lock. Under challenge, I grabbed a chair, stood on it, lifted the drop ceiling and cut one of the wires to the magnet, click, it opened (would be a fire hazard if door did not unlock when power was removed). I think they spent big bucks on their false "sense of security" I also pointed out that the data room could be accessed via drop ceiling on one side and drywall (that's tough stuff!!) on two of the three walls.

Yes, I used a Pap2 adaptor attached door tamperproof video/speaker phone. The model I used had alarm contacts just in case it was removed from the wall you can instant trigger an alarm system. You preprogram the extension it dials and it waits to here a touch tone code that NO NC contacts are activated to do with what you please. I do not remember specifically which door phone I used but here is a link to a exhibit which list several manufacturers. http://www.archiexpo.com/cat/home-building-automation-security/access-contro l-video-and-audio-door-phones-Y-652.html Vince APCN -----Original Message----- From: asterisk-users-bounces at lists.digium.com [mailto:asterisk-users-bounces at lists.digium.com] On Behalf Of c james Sent: Thursday, July 17, 2008 8:44 AM To: asterisk-users at lists.digium.com Subject: [asterisk-users] Magnetic door locks I have an opportunity to interface asterisk with a security system to open their magnetic door locks.
