IAP = 0.19A Each notification appliance has a diode in it that only allows current to pass through it in one direction (think of it like a one way valve). So, when the regulator is not actively supplying a load, this current flows to the ground (GND) terminal. 24VDC nameplate requires a minimum 20.4VDC for secondary power in the battery. NFPA 13 The ADJ pin current is only typically 0.2 uA, 5 uA max for loads under 100 mA. fire alarm The fire alarm trouble indication should clear and the system should appear normal in all respects. Fire alarm batteries should fully recharge within 24. rate of rise alarm is pre-configured in the detector. Moreover, this loss in power (PLOSS) is a function of the input voltage (VIN), output volage (VOUT), output current (IOUT), and the quiescent current (IQ). May 2020 Some may also refer to this as a fire alarm control panel or fire alarm panel. multisensor fire detector (Full alarm current from panel) = 0.3 Amps First multiply I1 (0.05 Amps) by T1 (324 Hours) = 1.2Ah (Amp hours) Then add on I2 (0.3Amps) = 1.5Ah Then multiply the whole by the aging factor (1.25) How to test your smoke detectors and fire alarms.
