11.4 Processing fire alarm signals
The principle of operation of the fire alarm line is as follows:
1. In its normal state, the fire alarm line has to be closed.
2. When the line breaks and remains in the broken state within a certain period of time
(see 15 Appendix 3. The controller numeric configuration parameters, D0006
parameter), the controller is:
● Unlocking (opening) all actuators connected to it.
● Entering the special "Fire alarm" state.
● Enabling sound signals of the "Fire alarm" state (see 13 Appendix 1. The controller
audible signals).
● Entering the standby mode until the fire alarm line is recovered (closed).
3. When the fire alarm line is recovered, the controller resumes its normal operation.
11.5 Functioning of general purpose outputs
The controller has general purpose outputs with a shared collector. Their use is configured by
reassigning terminals. By default, the outputs are used to indicate the access request.
A low-level signal is sent to the output, when reading a staff pass, which has a mode with the
enabled function Require guard approval for passing (Rules -> Special Rules tab).
To allow access, you may push the turnstile A or B button, or the gate START button, or the door
opening button.
To deny access, you may push STOP button on the control panel of the turnstile or the gate, or the
door BLOCK button. The duration of the signal request is configured in the system control program.
11.6 Functioning of the controller input/output protection circuits
11.6.1 Reader power supply circuits
The reader power supply is protected against overload and reverse polarity by resettable fuses with
500mA tripping current and protective diodes.
With an increase of current consumption above 500mA, the reader power supply circuit will
automatically turn off. When the voltage, supplied to reader power terminals, is higher than the
voltage of the controller power supply, the protective diodes will close, preventing damage to the
PSU and the controller.
After the cause of emergency is eliminated, the reader power supply is recovered automatically.
11.6.2 Controller outputs
The controller outputs with a shared collector and a shared outlet are protected against overload,
overvoltage and reverse polarity by resettable fuses with 100mA tripping current and protective
diodes.
