5.1.1.1

Zone line input (EOL capacitor)

This mode should normally be used. It has the lowest zone line current consumption since
the End-Of-Line device is a capacitor, 470 nF (±10 %).

Maximum allowed cable resistance is 50 ohm.

Maximum allowed cable capacitance is 50 nF.

Maximum allowed zone line current consumption is 1.5 mA.
5.1.1.2

EX zone line input (EOL resistor)

This mode must be used when the zone line input is intended to be connected to
intrinsically safe devices e.g. intrinsically safe detectors or manual call points via the
Galvanic isolator MTL5061 (2820). The end-of-line device is a resistor, 10K (±5 %) with a
body surface area > 230 mm

Maximum allowed cable resistance is 40 ohm.

Maximum allowed cable capacitance is 70 nF.

Total zone line current consumption is < 1.0 mA.
5.1.1.3

Zone line input (EOL resistor)

This mode is typically used in New Zealand where only EOL resistors are allowed.
to be used when any of the other types cannot be used (e.g. for some older type of
detectors and not Panasonic detectors). The EOL resistor has the highest zone line current
consumption since the end-of-line device is a resistor, 4K7 (±5 %).

Maximum allowed cable resistance is 50 ohm.

Total zone line current consumption is 2.0 mA.
Note: Older version of 4580 boards PCB9287-2B requires 10K end-of-line resistor while
the newer version PCB9287-3A requires 4K7. Table 4 and Figure 8 illustrate the two
distinctive differences between the two PCB versions in both hardware and software.
