IMPORTANT NOTES;-

 

   

a.  Do not use metal ties or straps as they can damage the    

          Detecting cable. 
   

b.  Do not over tighten the cable ties. 

   

c.  Detecting cable should never be installed between pipe-   

   

work and its insulation. It must be installed on the outside  

 

  of any insulation finish.

 

   

d.  ‘aqualarm’ WARNING LABELS (WL-1) should be fitted at    

   

5m intervals along the entire length of all cables installed.  

 

  Where cables go through walls etc. the WL-1 should be 
   

 

fitted either side of the wall.

 

 

Section B  

 1. Testing 

Installed 

Cables

 

 
  i. 

 

When all your  Leader / Detecting / Jumper cables have been 

   

installed, the total length should be Tested as follows :- 

  ii 

 

Ensure that all the cables are connected together BUT DO NOT  

  CONNECT the Leader cable to the Control Panel AT THIS STAGE. 

  iii.   

Connect the End of line resistive plug (EOL-2) to the end of the  

  last length of cable installed. 
  iv.   

Carry out the following ‘TEST’ using a Multimeter to ensure the 

   

integrity of the installed cables. 

  v.   

Set Multimeter to read a resistance above 100 ohms. Connect  

   

the Multimeter leads to the bare cores of the Leader Cable. The  

   

following should be noted:- 

 

 

 

   

CONDITION                                POSSIBLE FAULT 

   No 

resistance

  

 

 

a.     EOL-2 not fitted at end (Open 

Circuit)               
   

 

   

 

 

b.     Cable disconnected along the 

   

 

   

 

 

        installed length. 

   

Resistance reading  

 

   

below 45 ohms 

 

 

a.     Cable is damaged (Short Circuit) 

   

 

   

 

 

b.     Cable is wet (Rectify) 

 

   Resistance 

reading 

   

above 50 ohms.   

 

a.      All cables are correct. System is 

   

 

   

 

 

         ready to connect to Control Panel.
