Technical support / Access system
« on: May 04, 2006, 06:42:44 PM »
Am looking to use your plc's to control our whole building
the AC system, Door Access, Alarm interface to call security monitoring service,
Garage door openers as well as KWH Logging and monitoring
Started on the code for the 8 10ton water loop AC System
and the cooling towers
Now i need to start on the Door Access and controll system
but i need some examples of doing a keypad encoder!
I would like to use six or more numbers for the codes and
like it to communicate to the master plc to autenticate the code entered!
then send back to the initiating plc to open door if code is authentic.
the problem is there is no standard on access systems
some use 4 dig + * like our mag lock
some use # first then code like our Road Gate
some use just 4 numbers no #* or enter like our alarm system
some use 6 numbers and the # sign
not to mention every time someone leaves,quits,gets fired, Ect.
it takes all day to remove or reprogram there codes out of the many systems used
and now we are adding 20,000 more sq ft
9 garage doors,9 man doors, 6 more alarm keypads\systems, 2nd access gate
Point is I would like to get to the point of 1 place to make any changes or additions
and also handel Lighting control, Fans, alarm, HVAC Systems, Energy Management,
Access controll, Ect.... and your system has the power,Flexability, and price range to
Do the job Centrialized Building Controll System.
Just need some application notes,examples to guide me
down the right path and help me get started.
This may be a good product addition to your line.
or a startup line for some programing guru out there.
Any notes on KWH logging would be helpfull to.
