Diagnostics (Wireless Controls)
LED1, LED2, and LED3, located on the sensor of model
WZS respond to diagnostics by exhibiting specific blinking
patterns. View their response by pressing the Test button
(see Table 38, p. 95).

models, respond to diagnostics by exhibiting specific
blinking patterns. They respond independently of any user
action (see Table 39).

Testing Signal Strength (Wireless Controls)
To initiate a signal strength test, push the Test button on
the sensor (see location of Test button in
• Models WZS: LED1, LED2, and LED3 respond by
indicating signal strength. You can view them on the
sensor (Table 40) and the receiver
• Model WDS: Test symbols on the sensor display
indicate signal strength
LED3, on the receiver, respond by indicating signal
strength (Table 41).
