DI/DO card is connected to the video capture card and is used for connecting guard loops (sensors), relays and in some cases analog sensors to the control system - the server with installed INTELLECT™ software. General information about sensors and relays is given in the table:
Type of device | Description | Functions | Operation conditions | Changes in operation condition | Examples of devices |
Sensor | Interface line of external sensor and control system | Informs the control system about changes in sensor status | Closed– logical one Open – logical zero
| Opening/closing – when sensor detects the alarm | Annunciators (smoke, heat, window, etc), button |
Relay | Interface line of control system and executive device | Changes operation condition of executive device on command from the control system | Closed – logical one Open – logical zero
| Opening/closing – on command from the control system. | Annunciators (light, sound, etc.), mechanized gates |
| Analog sensor | Interface line of external sensor and control system | Informs the control system about changes in sensor status | - | In analog (continuous) mode. | Temperature, humidity, pressure, etc. sensors |
Electrical and technical specifications of Sensor-Relay cards are given in Appendix 6. Electrical and technical specifications of Sensor-Relay cards section.
