You can wire #1 and #2 Alarm Outputs and Digital Inputs.
The prerequisites are:

Model Number - Table 3 = XX1
Refer to Figure 2-19 and follow the procedure in Table 2-18 to wire alarm outputs or digital inputs.
The alarm output is a dry contact closure.
Step
1 Open the recorder door. Loosen the captive screw in the chart plate and swing the plate out.
2 Locate connector J3 and J4 on the alarm output/digital input printed circuit board (refer to
Figure 2-19 for location).
3 Remove the unwired plug from J3.
4 Run the digital input wires through the desired knockout.
5 For CE Mark conformity, install the ferrite filter as shown in Figure 2-11.
6 Strip insulation from the end of each wire.
7 Loosen the screws in plug J3 terminals and position the plug as you would to plug it into J3.
8 Insert the wires for the digital inputs into the appropriate screw clamps as shown (refer to
Figure 2-19). Note that you can wire the contacts in an and /or fashion, so that both contacts
or either contact initiates the configured action. Tighten the screws to secure the wires.
