END-OF LINE CAPACITOR FOR MEASURING WIRING IMPEDANCE OF EMERGENCY NOTIFICATION CIRCUITS
摘要
<p>A system includes a capacitor, a plurality of notification devices connected in parallel with the capacitor, and a controller. The controller is capable of determining capacitance of the capacitor during charge-up of the capacitor, and the controller is capable of determining the wiring impedance of the emergency notification circuit during discharge of the capacitor.</p>
