How to shield the jb-3208g automatic fire alarm host equipment in Songjiang, Shanghai?

Enter the programming menu, password 3208, select "Attribute Configuration" after entering, select the loop number of the point to be shielded, press OK after entering, select the point to be shielded after entering, press the "Shield" button after the cursor moves to this point, the word "Shield" will be displayed on the point, and then exit and save.

There are instructions in the equipment definition, you can also read the instructions, and you can also download the instructions from the insider's fire control library. But after shielding, the shielding light of the controller is on, and you will know after inspection and acceptance.

Mask: Press this key in controller, attribute configuration and programming to name a loop point number in the selected place as a mask point, and then press the mask key, which is called "reserved point". Press it again to exit the "shielding" state, and the shielding key can quickly view the shielding information.

Because there can't be empty numbers between the hosts in Songjiang, and then the loop capacity is relatively reduced, you need to enter the programming menu, use the administrator password, enter the shielding address option, and correctly enter the loop number and address number of the point to be shielded.

Extended data:

The capacity of the regional alarm controller (that is, the number of components it can monitor) also varies with the product model, generally dozens of components.

The regional alarm controller usually patrols to detect the working state of detectors in the alarm area, and sends out audible and visual alarm signals in time when finding fire signals or fault signals.

If it is a fire signal, at the same time of sound and light alarm, some area alarm controllers also have linkage relay contacts to start the functions of some fire-fighting equipment.

These fire fighting equipment include smoke exhaust devices, fire doors, fire shutters, etc. If it is a fault signal, it is only an audible and visual alarm, and the fire fighting equipment is not linked.

After receiving the alarm signal from the detector, the regional alarm controller sends out an acousto-optic alarm and transmits the alarm signal to the centralized alarm controller located in the fire control room.

The self-check button is used to check the faults (short circuit or open circuit) of each alarm line and send out simulated fire signals, and check whether the detector function and line conditions are good.

When a fault occurs, it will send out a fault alarm signal (only sound and light alarm, memory unit and linkage unit do not act).

The signal selection unit is also called the signal identification unit. The level amplitude of the fire signal is higher than that of the fault signal, which can trigger the conduction of the door shaft tube (while the low-amplitude fault signal will not make the input tube conductive).

Activate the relay, cut off the fault acousto-optic alarm circuit, send out a fire acousto-optic alarm, stop the clock, record the first fire alarm time, and at the same time link other alarm or fire fighting equipment through relay contacts.

The input voltage of the power supply is 220V, the AC frequency is 50U2, and the internal regulated power supply outputs 24V DC voltage for the detector.

In order to reduce false alarm, facilitate installation and debugging, reduce installation and maintenance costs, reduce the number of connecting wires, and know the exact position (part number) of the fire detector that gives the alarm in time and accurately, modern fire alarm controllers generally adopt pulse coding control system to form a bus structure with fewer wires.

Microcomputer or single chip microcomputer is used as the main control core unit, equipped with memory and digital interface devices. Therefore, modern alarm controller has strong anti-interference ability and flexible adaptability.

The capacity of an area alarm controller (that is, the number of components it can monitor) varies with different product models, generally dozens of components.
