Overview of equipment functions:
1. The equipment has a fully automatic patrol function, and the patrol period is arbitrarily set within 7 days according to the requirements of Party A (the user), usually 24 hours per cycle;
2、 Fire pump During patrol inspection, start patrol inspection operation one by one in low frequency and low speed mode pump The running time is not less than 20 seconds, usually set as 30 seconds per cycle;
3. During the automatic patrol inspection, the main low-voltage devices in the primary circuit of the fire pump control cabinet shall be given a pulse action signal not greater than 2S, and their action status shall be checked one by one;
4. During automatic patrol inspection, exit the patrol inspection immediately in case of fire signal and enter the fire fighting operation state immediately;
5. During automatic patrol inspection, if a fault is found, it will send out an audible and visual emergency signal and memorize and store the fault information;
6. It has overvoltage, overcurrent, short circuit, phase loss, water shortage and other protection functions;
7. During the fire patrol inspection, no pressure is generated on the pipe network, which effectively protects the pipe network!
Features and functions of fire intelligent digital patrol device
1. In case of fire during patrol inspection, the patrol inspection will be stopped immediately and the fire pump will be started immediately.
2. With complete functions, it can complete the low speed and pressure free patrol inspection of the fire main circuit and fire pump.
3. It has overvoltage, overcurrent, short circuit, phase loss, water shortage and other protections.
4. In case of failure during patrol inspection, the automatic patrol inspection device will generate an audible and visual start emergency signal,
5. Patrol operation parameters can be displayed through the interface. (Optional)
6. It has the function of upper telephone starting emergency signal.
7. RS485 communication interface is reserved for the equipment, which can complete remote transmission of the operation status of building automation.
8. In case of fire signal during patrol inspection, immediately exit the operation and switch to power frequency circuit
