Rang Dong’s Wireless Manual Call Point Supports Fire Safety

A wireless manual call point is an important device in a modern fire alarm system because it allows people to trigger an alarm quickly in an emergency. Rang Dong’s device model NBC01.RF is designed to support fire warning, device locating, and alarm control through direct button operation. The product uses RF wireless connection and a replaceable battery, making installation more flexible in homes, offices, hotels, schools, factories and warehouses. This article explores its specifications, key features, and practical applications for safer building management.  

Rang Dong, Vietnam’s leading innovator in lighting and smart technology, offers model NBC01.RF as part of its smart fire alarm product range. The wireless manual call point is a compact, flexible, and easy-to-operate device for fire safety systems.

Structure of Rang Dong’s wireless manual call point

The product uses a CR2450 battery with 3V voltage and 600mAh capacity. Its battery life is listed at 3 years, helping reduce maintenance effort during long-term operation. Because the device is battery-powered, it is convenient for installation in completed buildings or locations where wiring is difficult. 

NBC01.RF connects through RF technology at 444.6 MHz and supports a connection range of up to 100 meters in open conditions. 

The product size is compact at approximately 63 x 15 mm, with a listed weight of 0.4 kg. Its body material is Plastic ABS and PC, while the operating temperature range is from -10°C to 50°C (14-122°F). The device also supports operation in humidity conditions of up to 95 percent RH without condensation.  

Exceptional Features

The main advantage of this wireless manual call point is its 3-in-1 function. Users can press the device to activate the fire alarm system, locate the alarm position, or hush the alarm sound when needed. These actions are performed directly on the product, which makes operation simple in urgent situations. 

The RF wireless connection also adds flexibility to system design. Rang Dong’s model NBC01.RF can communicate with other fire alarm devices and the central fire alarm controller through a local RF network. If one device sends an alarm, other devices in the system can also sound the alarm. 

This helps create a connected fire warning network for buildings where fast information sharing is important.  

Another practical feature is smart monitoring through the app when the device is used with the central fire alarm controller. 

The product supports connection, management, and monitoring through the fire alarm system app, allowing users to check device status and receive alerts more conveniently. This is useful for homes, apartments, offices, small businesses, and properties where multiple people need to monitor safety conditions.  

The product is also designed for simple maintenance. The replaceable battery helps users maintain the device without complex wiring work. Rang Dong has designed the battery status to be updated visually on the mobile application, which supports better readiness management.  

RF wireless connection helps reduce wiring work during installation.

Applications

A wireless manual call point is suitable for areas where people must be able to trigger a fire alarm quickly and clearly. Rang Dong recommends installation in accessible positions such as corridors, emergency staircases and entrances. The device should also be used with suitable signage and should not be hidden or blocked by objects. 

Model NBC01.RF can be applied in residential spaces such as mini apartments, townhouses, and villas. In these environments, a wireless system can be useful because installation is faster and less invasive than traditional wired solutions. It also supports fire safety upgrades for buildings that are already in use.

For commercial and public spaces, the product can support hotels, event centers, offices, hospitals and schools. These locations often have many users moving through shared areas, so a visible and easy-to-reach alarm button can help improve emergency response. 

The product is also suitable for production environments such as workshops and warehouses, where fast fire warning and alarm location support are important.  

Regular testing helps keep the fire alarm system ready for use.

In order to maintain stable performance, users should check the device periodically. Rang Dong recommends testing operation once a month by pressing the device directly or checking through the app. Regular inspection helps ensure the wireless manual call point remains ready for emergency use.
