13. Tone Indicator
•This function aids installation by generating the different intervals of tones based on the strength of beam that the
receiver receives. When the monitor jack voltage is above 3.0V, which is good enough strength, then the tone is
continuous. The lower voltage, which means less strength, results in the shorter interval of the tones.

12. Alarm Memory Function
•When multiple sets of detectors are installed,
alarm memory LED will blink for up to 24 hours,
allowing users to check which set the alarm was
activated.
•After checking which set the alarm was
activated from, you can reset this function by
1) disable the function by selecting OFF on dip
switch #2, 2) pressing tamper switch. The
function will also be rest automatically 24 hours
after the alarm.
11. Environmental Disqualification Output
•When beam strength continues to be below 1.0V for more than 40 seconds
by various of reasons, the environmental output will be activated, providing
a notice that there have been impairments to the unit.
•For example, when the alignment of the unit has been tilted by animals,
hurricane, or an object is blocking one of the beams, the receiver outputs
an environmental output.
