I'm slowly assembling my M1G alarm system and I have a few simple questions regarding how to power it properly.
I plan on installing:
- three keypads on the databus
- five speakers on output 1 (two ELK-73 Echo plus three ELK-SP12F)
- one ELK-SP35 Siren on output 2
- one strobe on output 3
- one exterior siren on an output of a relay board
The exterior siren will be powered by an external power supply, namely one of the three outputs of an ELK-412K. My concern is that the five speakers, interior siren, three keypads, and strobe are all sourced by by the M1G's primary power supply (wall wart plus battery) and will overtax it. Is the primary power supply capable of handling the mentioned load?
Is it possible to augment the primary supply using one of the outputs of the ELK-412K? In other words, can I connect one of the 412k's 12VDC outputs directly to the M1G's 12VDC input? In effect, I'll be adding the 412K in parallel with the M1G's battery. Is this a normal practice or will this cause problems?
What other solutions are there to ensure the primary supply is not overloaded?
