The
Aux IO
terminal provides an open collector output which can be used
for alarm or auto function purposes. If the collision alarm output or the
Presence Alarm output has been configured to
Aux IO
, then the negative
of the alarm device must be connected to this terminal. The positive of the
alarm device must be connected to the Aux 12V Out terminal. Similarly, if
Aux IO
is auto-activated via a ChronoGuard auto-activation Time-period,
the device being switched (typically a 12V relay) must be powered from
the Aux 12V Out terminal, and have its negative switched by
Aux IO
. If
the
Aux IO
has not been selected as either an alarm indicator output or
auto-activated output, the
Aux IO
terminal will behave as a Com
termination point. All trigger signals, etc., have their return path to one of
the Com terminals
Com
The common termination point. All trigger signals, etc.; have their return
path to one of the Com terminals
NMI
The non-memory input. (A normally-open potential-free input). This input is
used to obtain a trigger signal. Momentarily connecting the input to Com
will cause the boom pole to raise, stop or lower depending on the operating
mode selected. Each trigger impulse received will cause the barrier to react
accordingly

terminals
Status
External boom status indication
. (A low current output signal). An
output terminal which provides a low current drive (approximately 4,5V DC,
20mA) to a LED which can be used to indicate the boom status remotely. If
more than three LEDs are required it is necessary to fit the CP78 multi-LED
driver card
Aux
The lowering input. (A normally-open potential-free input). Momentarily
connecting this input to Com will cause the boom pole to immediately lower
regardless of which position it is in, unless it is already fully lowered
FRX
The raising input. (A normally-open potential-free input). Momentarily
connecting this input to Com will cause the boom pole to immediately raise
regardless of which position it is in, unless it is already fully raised
