: I have a DSC 864 with 2 5500-z keypads. 8 zones hardwired. Plus the battery is a 12 volt 7 amp battery.
: Question is.I was installing my system and havent touched it for 2 months.. THe battery has sat uncharged for about 3 months. I just hooked it up and put it in the alarm panel. On the top of the board for the 864 there is a silver heat sink. My question is how how should this heat sink get? Right now it is pretty warm. I can put my fingers on it and it wont burn me but it is pretty hot to the touch.
: Is this because the battery is charging up? Or is this the normal operating temp of the heat sink.
: As far as the witing goes I used 22/4 for all the connections. (magnetic door switches, glassbreaks, motions, and also used 22/4 to wire up the transformer) Is this ok?
: Thanks alot
That's typical of the heat sink - it really depends on how much power is being drawn (battery, devices, etc.), but it's not unusual for it to get very warm.
22/4 is fine - you only need 2 of the conductors, so you'll have 2 left, but there's nothing wrong with that.
Good luck!
