Detailed Introduction of Functions
1. Fire Alarm
Under normal conditions, the monitoring system is in monitor mode. When fire situation occurs and temperature rises abnormally in the module, the heat detector will transfer the temperature behavior to the monitoring station and the monitoring station will treat and estimate the signal. When the monitoring station confirms that fire situation occurs, it will give off acousto-optic alarm signal and cut off the external power source of powered device. At the same time, it will transfer the alarm signal to the monitoring microcomputer and give off voice alarm automatically through telephone line or local area network.
2. Flammable gas alarm
When flammable gas exists in module intraoffice, it will catch fire and explode when contacting powered equipment. Therefore, this monitoring station is equipped with flammable gas alarm function. The flammable gas detector is in monitor mode under normal condition. When the density of flammable gas in protection area reaches set alarm density (25% of lower explosive limit), the monitoring station will give off alarm signal and will meanwhile transfer the alarm signal to the monitoring microcomputer and give off voice alarm automatically through telephone line or local area network.
3. Linking function
When fire or other warning situations occur, the monitoring station will automatically reel off control instructions to control unit in accordance with program content, and make it carry out relay operation, realizing linking control. For example, start linking fire extinguishing device to put out a fire or start blower fan to exhaust the flammable gas out of the room.
4. Anti-theft alarm
Under normal conditions, the anti-theft system is in monitor mode. When non-staff entering, the anti-theft system will give off alarm signal and will meanwhile transfer the alarm signal to the monitoring microcomputer and give off voice alarm automatically through telephone line or local area network. When the staff enters into the protection area, they will punch their cards to open door. At this point, the monitoring station will automatically close anti-theft system and start the anti-theft system automatically after closing the door.
5. Waterproof alarm
Under normal condition, the waterproof system is in the monitor mode. When the waterproof detector searches the water on floor of machine room, the waterproof system will alarm and meanwhile transfer the alarm signal to the monitoring microcomputer and give off voice alarm automatically through telephone line or local area network.
6. City planning power failure alarm
The powered device of module intraoffice adop ts power supply mode of main and secondary circuit. When the main power (generally electric supply ) failure, the secondary power will automatically. As the secondary power is generally supplied by storage battery, the working time is relatively short. Within a given time, if the main power couldn't recover and the secondary power is used up, the communication facilities will stop work automatically and bring about loss to users. Therefore, this monitoring station provides city planning power failure alarm, that is, when electric power is cut off and the secondary power is running, the monitoring station will meanwhile transfer the alarm signal to the monitoring microcomputer and give off voice alarm automatically through telephone line or local area network, to remind the staff treat as early as possible and ensure smooth communication. |
