draught fan connection.jpg The control panel can be automatically linked, so in most cases, the equipment which needs direct manual control, such as smoke exhaust fan, air supply fan, fire pump, spray pump, rain solenoid valve, water curtain solenoid valve and pre-acting solenoid valve, only need t...

fire alarm module connection with smoke ejector.jpg 1. Both the power and signal of the module are non-polar. The smoke exhaust port is dry contact N/O connected with alarm panel for feedback signal sending. 2. EOL resistor should be wired at end of line on side of feedback, not near I, G terminal....

fire module connect to fire alarm device.jpg Connect fire alarm device to fire module. The Alarm bell and sound-light warning devices will be triggered by control panel and no feedback signal is required. So, terminal 1 and G is connected with EOL resistor. Use the handheld programmer to set the mo...

4.7K EOL resistor should be wired to the circuit. Use handheld programmer to set the control module as Dry contact output and self-response according to code on the fire alarm system manual.

fire alarm control module terminals.jpg 1. Signal line 2 - buses wire Z1 and Z2 should use flame-retardant RVS twisted pair with cross-sectional area greater than 1.0 mm. 2. The power supply lines D1 and D2 should use fire-resistant BV lines with cross-sectional area (> 1.5mm). 3. G, NG, V+, NO, CO...

Fire Alarm System modules are used to monitor or control the fire fighting device. There are input module, output module, input and output module, isolation module, relay module, switching module, multi-line control module, etc. 1. Input module is used to receive signal input, and the input equipmen...

Unattended High Voltage Substation needs high security protection cause it is always built in remote and uninhabited areas and with expensive devices. So, it needs 5 types monitor and sensing devices for the security protection. 1. Telemetry (telemetry information): Acquisition and transmission of o...

Most mine production sites are underground and far from the ground, complex terrain, dark light, harsh environment, and with harmful, poisonous, flammable and explosive gases. So, early Warning System and Video Monitoring System is needed fro mine industry. The security equipment for mine safety pro...

More than 50 professional firefighters was formally stationed in the coal chemical industry site. The gas extinguishing and prevention station of the coal chemical project was put into operation. safety guarantee is provided for coal chemical production.
