Q-20: Can I use the "HU-2" (an optional heating unit) for AX-TFRs?

A-20: No, because the HU-2 works with 24VDC, AX-TFRs' LSH20 (3.6 VDC)
can not support the heating module. Not to mention the fact that AX-TFRs do
not have holes to put through wires, outside power supply cannot be
accommodated either. When using AX-TFRs in a tower, usage of the HU-2 is
an option; however HU-2 will not produce enough heat to resist frost and
condensation inside the tower.

Q-21: What outputs are there?

A-21: There are four kinds of outputs, alarm(Form C), tamper (Form C), low
battery and D.Q. Each output is available with choice of N.C. or N.O.

Q-22: What are initial settings for switches?

A-22: The initial settings for switches are as follows.
Interruption Time
Battery Saving
Intermittent Output
N.O./N.C. selection for Low
Battery and D.Q. outputs

Q-23: When does D.Q. output work?

A-23: D.Q. output will send a trouble signal when the beam strength reaches
below acceptable levels for more than 20 seconds, due to rain, snow, or
heavy fog. D.Q. output will return to "OFF" if reception is regained for more
than two seconds.
