4.11.4 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 4-40. Notice grouping of terminals; power terminals are shared by two
inputs.
