[asterisk-users] Fwd: Re: Asterisk as a Condo door opener/intercom
Asterisk as a phone system makes perfect sense in a condo. You can get
all the DID's you want and eliminate costs for the owners. You can offer
standard FXO for people who don't care and IP sets for people who want
to upgrade to feature sets.
Your door openner is a piece of cake.
1. Create an option in your dialplan only in the from-access-door
context that reads DTMF from the called station only.
2. Use this to access an external program to turn on a serial port line
for 10 seconds.
3. This line drives a solid state relay (~$30) so you won't blow the
sink current on the PC port that drives a standard door lock.
A commercial door strike is about $100. The program to run the port is
childs play. Here is a test prog I used for turning on a power hungry
last printer. Change the comments and the sleep time and you're done.
/*
* lpon Lineprinter ON
* *** test program only **
*
* (c) David Cook, 1994
*
* Set signlal lines on serial port to turn on 5vdc
* signal. Used for solid-state relay (low current
* draw on RS232C port) to switch high voltage/high
* current load for printer.
*
* Part of an intelligent print spooler to only power
* on/off high draw printer when required.
*
* Usage: lpondevice bits to set
* For example, lpon /dev/cua4 4 to set bit 3 on
* port /dev/cua4.
* 4 = 0100 or bit 3 which is DTR
* 2 = 0010 or bit 2 which is RTS
* 6 = 0110 or both DRT RTS

The same argument could be made for any commercial solution. Why use
Asterisk when we could throw $4,000 at our problem for a commercial
solution?
I'd like to have a solution that would have the features you suggest for
$400.

Search the lists. Some hints:
Viking electronics makes a door box that connects to any analog line
(IIRC e-20).
They also make a DTMF keypad that integrates in series with any analog
line. They might also make a door box with a DTMF keypad on it.
Sandman makes a relay that will get energized when there is a ring on
the line which could be used to unlock the door.
However, why would you use asterisk? Using asterisk for the sole
purpose of MDU entry system is like using windows for asterisk, it
works but why?
Go for the commercial solutions, it comes with a geziilion options for
your setup one of them the ability of chosing an apartment, another
add key fobs, another one is the ability of using a code for the
residence (not guests) to unlock the door. Also the interface with
asterisk you will have to build one from scratch. The commercial
solutions have em built in.
