The following procedures are to be performed before attaching control head to cylinder valve 

(refer to Figure 4-31):
1. Remove pilot port outlet protection cap from valve of cylinder to be equipped with control 

head.

2. Be sure control head is in "SET" position.
3. Arrow on reset stem should line up with "SET" arrow on nameplate.
4. Connect heat detector tubing securely to diaphragm chamber of control head as follows:

Install a 3/16-inch tubing nut at the termination of the pneumatic detection tubing. Attach 

the 3/16-inch tubing nut to the diaphragm connection on the pneumatic control head. 

Although the tubing for an HAD detection system is 1/8-inch O.D. copper tubing, the 

connection to the pneumatic control head is 3/16-inch O.D. copper tubing. The transition 

from 1/8-inch O.D. copper tubing to 3/16-inch O.D. copper tubing is made by means of a 

3/16-inch to 1/8-inch tubing reducing union.

5. If a Tandem Pneumatic Control Head (Figure 4-32) is required, both heads must be 

connected using 3/16-inch O.D. pneumatic tubing (Part No. WK-802366-000) provided by 

Kidde Fire Systems.

Note: If a mechanical pullbox is supplied, proceed with steps 6 through 8.
6. Connect control cable conduit to control head. Remove control head nameplate exposing 

manual release chamber.

7. Loosen screws on cable clamp and feed cable through hole. Tighten the set screws 

securely, allowing the cable to sag a little. Do not pull the cable taut. Cut off excess cable.

8. Make certain locking pin and seal wire have been assembled to nameplate. Local control 

lever should be parallel with nameplate. Assemble nameplate to control head, being sure 

to fit the small shaft into the cover bearing and the large pin under the trip lever.

9. Assemble control head to pilot control port. Tighten swivel coupling nut securely.
