7641B end-of-line resistor/diode assemblies are required when connectingthe fire alarm control panel (FACP)to releasing solenoids. Theyallow the FACP to supervise the wiring between itsnotification appliance circuitsand the releasing solenoid.
To allow the panel’s internal ohmmeter to check the continuity of the wires (supervise the wires), the end-of-line resistor is at the end of the loop: the last device. Fire Before getting into the importance of the end-of-line resistor, though, we have to understand the importance of...
