KN-688 Alarm Control Panel

Brief Introduction
1.Telephone alerting: The KN-688 alarm control panel offers automatic alarm with six phone lines connected to the desk phone and cell phone of the users, the alarm receiving center and so on. (Available for A type device)
2. Automatic code matching: It owns 100 detection zones for learning and matching the codes of 100 wireless detectors in total.
3. Wireless connection: The product is stored with 1 million address bits for connecting to the detectors wirelessly. Therefore, the signal interference of the same address will be significantly avoided and it is easy to expand the address storage capacity.
4. Remote control: It allows users to use phones to control the alarm control panel for remote sound monitoring, signaling the alarm, recording, remote arming and disarming, silencing the alarm and other functions.
5. Emergency calling: There is an emergency button on the panel. It is available in activating the alarm to signal for help via dialing six groups of stored alerting telephone numbers.
6. Wired detection zones: Four wired emergency detection zones support the connection with wired detectors that are normally opened or closed.
7. Intelligent detection zone: All the detection zones can be programmed as stand-alone standard detection zone, and the arming zone for 24 hours without disarming.
8. Smart identification: This alarm control panel performs with automatic identification on the signals of diversified sensors, automatic discrimination between the low alerting situations like IR detector, door sensor and the high level of alarm situations like smoke, coal gas and so on. Regardless of arming or disarming status, the product will signal the alarm when the signals of coal gas, smoke, fire and other high level alarm situations are detected.
9. Timed arming and disarming: Users can set two groups of timed arming zones and two groups of defense areas disarmed at fixed time. At the set time, the alarm control panel will start and close the arming state automatically.
10. Power failure protection: The function that has been set previously is not subjected to the power failure.
11. Information indication: This product is configured with the LCD screen that displays the time, alarm defense zones and indicates the operational function, alerting, low voltage of battery, disconnection of telephone line, recording and alternating current failure.
12. Alerting priority: The A type product has the alerting priority when something dangerous happens even if the phone line is busy in calling.
13. Audible alarm: In the telephone alerting, the alarm control panel will automatically play the audio record of 20 seconds that is made in advance. This function is available for the A type product.
14. Information protection: It needs to input the password to modify the information of the product.
15. Power supply: The backup battery enables the device to work normally for 24 hours in the alternating power failure.
16. Panel operation: It is convenient for users to use the functional keys on the control panel to accomplish any operation.
17. Networking: This alarm control panel supports networking to the 110 police center to send the alarm information. (Applicable for A type device)
18. Information inquiry: 50 records can be remembered in the product, facilitating the inspection on the operation status.
19. Dial Mode: Dual audio frequency dial
