5.2.5 Input and output signals and their parameters when operating the turnstile
The microcontroller set on the CLB processes the incoming commands (i.e. traces the status of
contacts “Unlock A”, “Stop”, “Unlock B” and “Fire Alarm”), keeps tracing the signals from the arm
rotation optical sensors and from the intruder detector (contact “Detector”), and sends commands
to the control mechanism basing on those signals. It also processes signals for the external
devices: indication on the RC-panel (“Led A”, “Led Stop” and “Led B”), the signal of hub turning in
the corresponding direction (“PASS
А
” and “PASS
В
”), the signal about readiness of the turnstile to
effect the current command (“Ready”), alarm output signal (“Alarm”) and relays the signal of the
current status of the intruder detector (“Det Out”).
The turnstile is operated by input of a low-level signal to the “XT1.L” connector block contacts
“Unlock A”, “Unlock B” and “Stop” relatively to the “GND” contact. As the control element there can
be used a normally open relay contact or a circuit with open collector output at that. At the
emergency unblocking device input the turnstile control is carried out by elimination of a low-level
signal from the “Fire Alarm” contact relatively to the “GND” contact. As the control element there
can be used a normally closed relay contact or a circuit with open collector output at that (see
Note:
For generating a high-level signal at all the input contacts (“Unlock A”, “Stop”, “Unlock B”,
“Fire Alarm” and “Detector”) “2 kOhm” resistors connected to the power supply bus “+ 5V”
are used.
The control element provides for the following signal characteristics:
Relay contact as the control element:
minimum switched current ........................................................................................... 2 mA
closed contact resistance
(considering resistance of the connected cable) ............................................. max 300 Ohm
Circuit with open-collector output as the control element:
voltage at closed contact (low - level signal at the CLB input) ................................ max 0.8V
