Connecting the Alarm Indicators

Use the following procedure to connect an alarm indicator to the chassis:

Step 1 Obtain sufficient wire for the desired connections. You will need two wires for each set of relays, or six separate wires to connect all three relay contacts. Use the gauge of wire required by the audible or visual alarm indicator equipment you are using (14 AWG maximum gauge).

Warning Use copper conductors only. Statement 1025

Caution The alarm contacts on the Cisco uBR10012 router are only relays and do not provide any power from the unit. These relays are rated for 60 VDC, 1 A maximum—ensure that the connected alarm equipment does not exceed these voltage and current ratings.

Step 2 Strip approximately 0.31 in. (8 mm) of insulation off the ends of the alarm indicator wire (see Figure 3-24).

Step 3 Connect one set of alarm indicator wires to the alarm terminal block as follows (see Figure 3-25):

a.Connect one lead to the common (COM) terminal.

b.If you are wiring the router in with other equipment for the alarm indicators, wire the other lead to the normally closed (NC) terminal.

c.If you are wiring the router in parallel with other equipment for the alarm indicators, wire the other lead to the normally open (NO) terminal.
