what’s a fireplace Alarm Supervision?

before we get too a long way into this, let’s define what a supervising station is. It’s a facility that receives indicators from alarm techniques and is staffed normally with personnel that may reply to the signals. This sounds simple sufficient, however as we’ll aspect here these can also be within the same building that the hearth alarm gadget protects or they can also be faraway from that place.
