If the detector is connected in the above manner and if a fi re alarm is signalled, with the alarm resistor connected
between terminals 12 & 13, then the alarm resistor will appear across terminals 3 & 4. The EOL resistor connected
between terminals 10 & 11 normally appears across terminals 3 & 4 and in the event of a fault the resistor appears open
circuit. If terminals 3 & 4 are disconnected from the fi re panel, these wires then provide a RS485 connection to the
detector. This connection may then be used to up load or down load information to the detector.
