Question
How many NGP keypads (without readers) can be connected downstream from a NGP-2220 or NGP-3320? And how many NGP keypads (with readers) can be connected downstream from a NGP-2220 or NGP-3320?
Answer
Each panel has a downstream device maximum capacity of 96. Reader and I/O modules are also counted in the total. So the limit is 96 with no other modules installed. Please also note the power limits below.
The main panel power supply only has 650 mA (US), 600 mA (Europe) of aux power.
