Re: Ademco 50P - Unable To Disarm

Actually I think it's more practical to do the calcs on paper with in-alarm
ma ratings of all devices.

| Okay, I'm sorry I jumped on you.  If you like the number you are currently
| using for the installer code and don't wish to learn a new one, then
| program in a completely new installer code, then create a master code
| consisting of your old installer code.  You get to keep using the same
| number, except now it will be a master code.

| I wasn't clear from your system description whether you have any auxiliary
| power supplies.  If not, it sounds like you may be pushing the limit.  The
| quick and easy way to get the auxiliary current draw is not to calculate
| it, but rather, to measure it.  Set your meter on a current scale that
will
| handle at least 2 amps.  Disconnect everything from terminal 6, connect
the
| positive meter lead to terminal 6 and the negative meter lead to all the
| wires you removed from terminal 6.  Read the current:  the panel is
| specified for a maximum of 750 ma aux power.  Personally, I prefer not to
| push it to the limit.

| each, expansion modules at xx ma each, and so on.  If you were seriously
| overloading the power supply,. it would let you know.
|
| However, your batteries may be inadequate.  Since you have smoke
detectors,
| your system is supposed to operate for 24 hours on batteries, though I
| doubt the battery police will be knocking on your door.   To calculate the
| standby time, take the measured current draw and add another 300 ma for
the
| control panel itself, then divide that total into the total amp-hour
rating
| of the batteries you are using.  This isn't really the absolutely correct
| way to calculate this, but it will put you ballpark-close, and save me a
| lot of typing.
|
| Finally, I'd suggest you get at least one 6160 keypad.  Your system is big
| enough for an alpha keypad to be of value, and it's particularly useful
for
| programming purposes.
