3.14  Shelter/Room Alarm Connections 
 

During the installation procedure, several shelter/room alarm contacts/sensors (where 
applicable) can be connected to the Break Out Board in the LB cabinet. 

 
The following steps should be performed to connect an external alarm to the DRU: 

 

1.  Run a cable from the alarm contact/sensor to the DRU. 
2.  Loosen the domed sealing nut on the LB cabinet cable gland marked “ALARM”, which 

is located on the bottom-left side of the DRU – see Figure 3-32. 

3.  Feed approximately 72 inches of cable into the DRU and tighten the domed sealing 

nut on the cable gland. 

4.  Run the cable along the bottom of the DRU, then up the left wall to the external 

alarm terminal block – see Figure 3-35. 

5.  Remove 4 inches of the outer insulation to expose the individual wires. 
6.  Remove 0.2 inches of insulation from the wires to expose the copper conductors. 
7.  Remove the appropriate jumper cable(s) from the Break Out Board pluggable terminal 

block(s). 

8.  Insert the wires into the appropriate pluggable terminal block contacts and tighten 

the clamping screws – see Table 3-9 for a list of contacts.
