1. Overview of ZF-500 fire display disk:
The ZF-500 fire display disc is a Chinese-style fire display disc designed and developed using a microcontroller. It is used to display the detector position number and Chinese character information that have been fired, and to issue acoustic and optical alarm signals at the same time.It is connected to fire alarm controllers such as GST200, GST500 and GST5000 through the communication bus, and processes and displays the data transmitted by the controller.When using an alarm controller to monitor several floors or fire partitions simultaneously, a fire display disk can be set on each floor or fire partition to replace the area alarm controller.
2. Features of ZF-500 fire display disk:
The ZF-500 fire display disc is connected to the fire alarm controller through the RS-485 bus. Each RS-485 bus can be connected to a maximum of 64 fire display discs.The fire display panel can only display fire alarm information, and cannot display other information such as faults, actions, etc.The display area of the fire display disk can be set through the fire alarm controller, and this layer, this area or all information can be displayed.
3. Technical characteristics of ZF-500 fire display disc:
1. Working voltage: DC16.8V~DC27.6V
2. Display capacity: up to 126 fire alarm messages
3. Display range: Each screen displays 2 fire alarm information, the first is the first alarm information, and the second is the latest fire alarm information; when pressing the adjust display key, the first is the first alarm information, and the second is the adjust display fire alarm information
4. Wire system: It uses a polarized two bus connection with the fire alarm controller, and two DC24V power supply lines are required, regardless of polarity
5. Usage environment: &Nbsp; Degree: 0℃～＋40℃ relative humidity≤ 95%, no dew
6.  Static power consumption≤2W maximum power consumption≤5W
7. Execution standard: GB 17429-1998
4. Structural characteristics and working principle of ZF-500 fire display disk:
Key Description:
a.“Power saving/sound silence”Key: In the monitoring state, the function of this key is“Save electricity&rdquo: Control; In the alarm state, the function of this key is“Silence sound”.
b.“Self-test/release display”Key: In the monitoring state, the function of this key is“Self-test”In the alarm state, this key function is“Tuning and displaying”.
in:
A and B: Communication bus connected to the fire alarm controller;
D1 and D2: DC24V power supply wire, regardless of polarity;
Open the case cover on the top of the fire display disc, and operate the primary code switch, LCD clarity adjustment potentiometer and power switch.
working principle
This fire display disk uses a 51 series microcontroller and communicates with the controller through the RS-485 driver chip.The microcontroller drives the LCD screen to display the corresponding information and drives the corresponding sound and light indication.
