the coverage area. The green light should flash for up to 5 
seconds each time your motion is detected.  

 

Note: 

If the LED lights green steadily for up to 5 seconds, your 

motion has been detected by the MW sensor. 

E.

  If PIR detection is not obtained at the far end of the coverage 

area, remove the front cover and re-adjust the vertical position. 
Replace the cover and retest. 

3.11 MW Walk Test  

A.

  Remove the front cover. 

B.

  Verify that the MW RANGE control is set fully counterclockwise to 

MIN and enable the LED either by setting mode switch SW-2 to 
ON or by grounding the TST input. 

C.

  Start by moving into the coverage area at the far edge. The LED 

should light green for up to 5 seconds each time your motion is 
detected. 

D.

  If your motion was not detected at the far edge, advance the MW 

RANGE control slightly clockwise toward MAX and try again until 
your motion is detected reliably at the far edge. 

Caution!

 The MW detection range must not exceed the far edge 

of the desired coverage area.

 

E.

  Walk across the coverage area at various ranges and verify that 

your motion is consistently detected.  

Note:

 MW LEVEL CONTROL (see figure 4) may need to be set to 

maximum for achieving maximum area coverage.

 

3.12 Alarm Walk Test  

A.

  Make sure that the LED is enabled, either by setting mode switch 

SW-2 to ON or by grounding the TST input. 

B.

  Install the front cover in place. 

C.

  Walk across the detector’s field of view in different directions, at 

various distances from the detector, and verify proper alarming 
throughout the detector's coverage area (the LED lights red for 1.3 
to 5 seconds). 

D.

  When done, disable the LED by setting set switch SW-2 to OFF or 

by disconnecting the TST input (leaving it "floating").  

E.

  Remount the cover and fasten it to the base using the small screw 

at the bottom. 

Attention! 

To assure proper function of the detector, the range and 

coverage area should be checked at least twice a year. 
Furthermore, it is recommended that users perform a walk test at 
the far end of the coverage pattern to assure an alarm signal prior to 
each time the alarm system is armed. 

3.13 Resetting after Trouble

 

If trouble occurs while 

mode switch 3 is ON

, proceed as follows: 

  Search for masking material on the lens or a masking object in 

front of the lens and remove them, if found. 

  Reset the detector by walk testing: cross its field of view at the far 

end, causing it to alarm several times. 

If everything is back to normal, the LED should stop flashing, and the 
TRB relay should revert to the closed circuit state. 

Note: 

If walk testing does not cause the trouble alert to stop 

and 

mode switch 3

 

is ON,

 recheck for masking. Once masking is ruled 

out, the trouble must be due to faulty PIR or MW circuitry.  

 

4. MISCELLANEOUS COMMENTS 

This device has been tested and found to comply with the limits for a 
Class B digital device, pursuant to Part 15 of the FCC Rules. These 
limits are designed to provide reasonable protection against harmful
