Adjust and Test the Sensitivity 

NOTE:

 

The TSH is capable of being operated by a wide variety of 

power supplies and does not require regulated power.  
However, a certain class of power supplies called "switching" 
can sometimes interfere with operation.  Switching power 
supplies can produce line noise which affects the TSH by 
rendering it hard to adjust. 

1.  PERFORM the following if the TSH is hard to adjust. 

a.  REPLACE the power supply with a linear power supply, if 

possible. 

b. 

IF

 not, 

THEN

 CONNECT one 0.01 mF capacitor between power supply 

“+” and earth ground, and CONNECT a second 0.01 mF 
capacitor between power supply “–“ and earth ground (see 
Figure 5, “Connecting Capacitors to a Switching Power Supply.” 

 

 

Figure 5.  Connecting Capacitors to a Switching Power Supply 

2.  PERFORM the following test to make sure a problem does not exist 

after the installation is complete. 
a.  TURN UP the sensitivity up to the point just before it is open all 

the time. 

NOTE:

 

The effect of coupling the reader's energy though a body 
into the door tends to increase the sensitivity of the TSH. 

b.  From the outside of the door, PLACE hand on the reader and 

LEAN body against the door to see if the TSH can be triggered.
