The fire hydrant button is a device installed on the indoor fire hydrant for manually starting the fire pump on the spot and displaying the running state of the pump. The device is an intelligent addressable fire control system equipment. Can be incorporated into two bus alarm control system; Fire pump can be started directly; And can receive feedback information from the pump room, the LED light on the button indicates that the pump is running. The product has the advantages of simple structure, convenient installation, reliable operation, low voltage (DC24V) and small current, which can greatly reduce the project cost and bring great convenience to the selection and construction of supporting equipment.

The manual alarm button itself has a dip switch and is addressed in decimal. Two-wire system, with polarity. When the fire occurs, the glass is artificially crushed, the fire alarm light of the button is lit, and the controller sends out the alarm sound and displays the alarm address. The installation position is set at the landing and other places, about 1.5m above the ground. The button operating voltage range of 15 ~ 30VDC, power consumption of 200μA, equipped with a special test key, without breaking the glass, you can test its alarm function, for corridors or large factories need to share the address of the occasion, the button can also be parallel unaddressed manual alarm button.

The fault isolator module automatically isolates short circuits between wires in the SLC loop. When a short circuit fault occurs in the SLC loop, the fault isolator limits the number of detectors affected by the fault. When the short circuit is removed, the fault isolator module automatically reconnects the isolated portion of the SLC loop. The fault isolator module does not require any address Settings and is fully automatic. The fault isolator module is installed in a 4-inch deep standard junction box, in a surface mount box or in a fire alarm controller. It comes with an LED that lights up when the isolator is operating normally and often lights up when a short circuit is detected and isolated.

When the fire alarm occurs, the alarm controller starts the external control device to be linked through the output module, and receives the feedback signal from the external control device through the input module. External control equipment such as smoke exhaust valve, air supply valve, fire shutter door, non-fire power supply, fire emergency broadcast, etc. And the signal after the action is returned to the alarm controller through the module, which is convenient for the manager to grasp the scene situation. The product is an intelligent multi-purpose module based on an 8-bit microprocessor. The monitoring mode occupies an address in the loop. It can be directly connected to the loop bus, control the peripheral equipment through the alarm controller programming, and automatically update and record the latest information, which does not affect the loss of data after the power failure. It consists of an output port and an input port, and the two ports are independent of each other. The output port consists of two sets of contacts. The input port has a monitoring function to control the controlled device through an intermediate relay.

In case of fire alarm, the alarm controller activates the external control devices that need to be linked through the output module, such as alarm bells and non-addressed acousto-optic alarms. The ISL 350 output module, like the input module, is connected to the loop bus of the controller and installed near the control device.

Water flow indicator, fire hydrant, pressure switch and other fire fighting equipment should be equipped with a monitoring module for monitoring, monitoring module will be the status of the above fire fighting equipment according to the monitoring and alarm two states displayed on the controller. The monitoring module is equipped with a decimal dip switch, which can be addressed on the spot and occupy an address in a primary circuit of the controller. After receiving the field signal, the monitoring module sends the signal to the controller through the signal bus.

The Model 2033 intelligent heat detector is an addressable detector that provides firefighters with the exact location of a fire. The detector uses innovative temperature sensing technology and can set the temperature alarm at 57 ° C.

The smart photoinductive smoke detector Model 2088 is an addressable detector that provides firefighters with the exact location of a fire. The detector can be set to different sensitivity Settings to adapt to different environments. By collecting the smoke concentration value, the control panel can determine whether the detector needs maintenance. The Type 2088 detector uses a unique optical chamber design to respond quickly and reliably to multiple fire sources.
