RADIO OUTPUT
O
Outputs a DC voltage. This pin is controlled by the inputs to
Open
the MANUAL & SLEEP pin (pin 26). It operates as a toggle.
During normal operation it outputs a low level (high
impedance).
(Normal breakdown voltage)

ALM-B OUTPUT
O
ALM-A OUTPUT: Alarm A
ALM-B OUTPUT: Alarm B
The output waveform is shown below.
During normal operation these pins output a low level
(high impedance).
