4.8.3 LED Wiring
There are four 12-pin connectors on the 5880 board for connecting LEDs. Each LED gets its power from Pin 11.
Internal resistors are sized so that there is approximately 10 mA of current for each LED, no series resistors are
required. LED outputs can be mapped to output circuits. See Section 6 for programming details.
Wire the LEDs as shown in Figure 4-22.
On connector P1, Pin 12 is an open collector output for controlling a PZT. If used, the 5880 PZT will match the
PZT pattern of the on-board (or 5860) annunciator.
Note: The circuit connected to “Open Collector Output” (last pin on P1) must be current limited so that no more
than 100 mA of current is allowed to flow into the open collector transistor.

4.8.4 Dry Contact Wiring
The 8 input circuits on the 5880 board are for monitoring switch inputs-any type of switch supported by the
control panel can be used with the 5880. For example, you can use a 5880 to monitor pull stations, water flow,
tamper, reset, or silence switches.
Wire dry contacts as shown in Figure 4-23. Notice grouping of terminals; power terminals are shared by two
