5.2.6 Control modes
There are two speed gate control modes – pulse and potential. In both modes the speed gate is
controlled by sending commands (i.e. control signals combinations) to
Unlock A
,
Stop
and
Unlock B
control inputs and to a special
Fire Alarm
control input. Control command sending
algorithm changes depending on the chosen mode.
Attention!
Change the switch positioning, remove and install jumpers on speed gate boards with de-
energized equipment.
The control mode is chosen by
Pulse
switch on the speed gate control board (Fig. 9). Upon
delivery the switch is in
ON
position, which corresponds to pulse speed gate mode.
Shift the switch into
OFF
position to place the speed gate into potential control mode. Control
mode will be changed after speed gate being powered.
Pulse control mode
The mode is used for speed gate operation from RC-panel, wireless remote control and ACS-
controller with the outputs supporting pulse control mode. Speed gate operation at pulse control
mode is described in Table 7.
Control signal duration at sending control command to control inputs is to be not less than 100 ms.
The initial passage waiting time is 8 seconds and it is independent of control signal (pulse)
duration.
Control command sending algorithm, which is a combination of control signals, is given in
Appendix 1. A control command is an active front of the control signal (signal shifting from high
level to a low level) at any of the control inputs (
Unlock A
,
Unlock B
and
Stop
), in case there are
corresponding signal levels at other inputs.
Note:
Push the corresponding button on RC-panel to send control signals from the RC-
panel / WRC to the signal active front. Pressing the button corresponds to the low level of
the signal; non-pressing the button corresponds to the high level of the signal.
