Hainan Shidian IOT Fire Door Monitoring System Solution

I. Introduction to Fire Door Monitor

✰ Fire Door Monitor

Fire door monitor is a control device that displays and controls the opening and closing status of the fire door, and it is also a bridge and link between the center control room or fire automatic alarm system FAS (FireAuto-mationAlarmSystem) and the front-end electric door closer, electromagnetic door suction, electromagnetic release, escape door lock and other devices.

Second, fire door technology principle

Fire doors are commonly used in various types of buildings can be opened and closed fire separation components, some of the fire doors installed in the building due to the use of poor management of fire door products there are many safety hazards, if the fire control room can not be effective monitoring of the fire door's working status, it can not guarantee that in the event of a fire to play a role in preventing the fire from spreading, the spread of smoke, evacuation of people.
The fire door controller can monitor the switching status of the fire door and give alarm prompts to the fire door in non-normal state, so as to make it return to normal working condition and ensure its function is intact.

Third, the fire door monitor implementation standards

Article 6.5.1 of the national standard GB50016-2014 "Code for Fire Protection in Building Design", which was promulgated and implemented on May 1, 2015, stipulates that.

Normally open fire door should be able to close by itself in case of fire and should have signal feedback function. In order to ensure the function of fire doors to prevent the spread of smoke, Article 6.5.1 of GB50016-2014 Code for Fire Protection of Building Design stipulates that.
Fire doors shall be smoke resistant when closed.

It can be seen that the fire doors set up in the building in the event of fire, in addition to being able to close on their own, but also to ensure that the closure is in place. However, from the current situation of engineering applications, the use of fire doors in use in buildings is not optimistic, and there is a widespread phenomenon that fire doors cannot be closed or closed poorly due to the damage of door closers, sequencers and other accessories of fire doors. In order to effectively control the closure of normally open fire doors in the building and supervise the working status of all fire doors (including normally closed fire doors), it is necessary to set up corresponding monitoring and control systems for the unified management of fire doors set up in the building.

IV. Overview of our fire bus

Our fire bus is a long-distance multi-host communication field bus, which is different from RS485 and CAN bus in that it adopts the unbalanced transmission method, transmitting data and supplying power to the nodes at the same time. That is, through the two wires, that is, can transmit data can also supply power for the nodes on the bus. This is the same as M-BUS, but different from MBUS it can provide nodes with a high current of more than 2A. Due to the use of unbalanced transmission of data, the bus is designed to be a non-polarized, bus, the hosts adapt themselves to the baud rate on the bus, automatic synchronization.
The power supply range of the bus is 12V~32V, the load capacity on the bus is strong, the distance is far, and the anti-interference ability is far more than RS485 and other buses.

❥ Main Functions

Inputs and outputs with short-circuit and disconnection protection and detection functions

• Remote online monitoring using the Internet
• Fire door monitors have multiple status indicators
• Fire door monitor with self-test function
• The fire door monitor receives the fire control signal and controls the closing of the fire door.
• The fire door monitor allows for quick diagnosis and identification of fault conditions through buzzers and indicators.

❥ Main Features

• Two-bus non-polarized design to avoid damage caused by wiring errors
• Signal + power transmission method, reducing wire and labor costs
• Reduced line redundancy with any topology wiring
• All-in-one design with built-in terminals, no need to install a junction box
• Active status reporting, no need for passive response, quick response
• Addresses are actively reported, eliminating the need for cumbersome setups

❥ Program Comparison

☑ Our Solutions

❥ Convenient on-site construction

The bus adopts unbalanced transmission mode, the cable selection is more arbitrary, do not need to use differential lines, the use of general RVV line can be. The bus topology can be connected arbitrarily, which greatly reduces the difficulty of field wiring, how to save wires on how to wire. The bus is designed as a non-polarized bus, in the application of bus-powered systems, engineers do not need to remember the positive and negative polarity, and do not need to match the resistance of the RS485 and CAN bus, which greatly reduces the technical requirements of the engineering and construction personnel.
