Assembly & Operation Manual

Note:
For generation of high-level signal at all input contacts (“Unlock A”, “Stop”, Unlock
B”, “Fire Alarm” and “Detector”) 2kOhm resistors connected to the power supply bus
“+ 5 V” are used
Figure 6 – ACS control element - normally open relay contact
Figure 7 – ACS control element - circuit with open-collector output
The control element must provide the following signal characteristics:
the relay contact as the control element:
minimum switched current .......................................................... no more than 2 mA
closed contact resistance
(with the resistance of the connected cable) ........................ no more than 300
Ohm
the circuit with open-collector output as the control element:
voltage at the closed contact
(low - level signal at the CLB input) ............................................ no more than 0.8
V
5.2.6 Control modes of the turnstile
There can be two control modes of the turnstile: pulse and potential. In both modes
turnstile control is conducted by command issuing (namely by combination of control
signals) on operational control inputs:
Unlock A , Stop and Unlock B and special control
input Fire Alarm . Depending on a chosen mode the procedure of command issuing
changes (see table 5 and 6).
Warning!
Installation and removal of the jumper is to be done only when the turnstile is
switched off.
