5.5.1.1

 

Disabling Detector Edge Sensors and Detector End Cover Sensors 

Detector edge sensors and detector end cover sensors should be disabled on both detectors. 
Proceed as follows: 

 

Procedure Details 

1.

 

Remove the detector side cover 

2.

 

Remove the detector edge cover. 

 

3.

 

Locate the connectors for the end cover 
sensor and for the edge sensor. See photo 
on the right. 

4.

 

Disconnect one or both of the sensors as 
required. 

5.

 

Place two jumpers on each connector as 
shown in photo. 

This will establish a 20 k

Ω

 substitute 

resistance for each of the disconnected 
sensors. 

 

5.5.1.2

 

Disabling Detector Top Cover Sensor and Rotate Gear Cover Sensor 

 

Procedure Details 

1.

 

Remove the detector top cover. 

 

2.

 

Locate the two cover collision boards. 

The collision board that plugs into the EDC 
board of detector 1 serves the detector top 
cover sensor. 

The collision board that plugs into the EDC 
board of detector 2 serves the rotate gear cover 
sensor.
