Status indicator | flush mounting, 230 VAC
Product description
This flush-mountable HVAC alarm unit is created to produce visual alerts utilizing green, yellow and red LEDs. It indicates the operational condition of HVAC systems in hard-to-reach locations.
It communicates through Modbus RTU and operates on a 230 VAC power supply.
Its enclosure allows for both surface and flush mounting, and it features an IP30 protection rating against dust ingress.
Additional specifications and description
Is the ventilation system operational at the moment?
The ALFC8 has been designed to generate visual notifications for monitoring the status of ventilation systems or HVAC installations. It employs green, yellow and red LEDs to communicate these visual alerts. This unit is particularly advantageous when HVAC systems are situated in hard-to-reach areas. Utilizing this alarm module allows you to confirm the operational status of your ventilation system and promptly identify any potential issues.
Seamless installation
The ALFC8 visual alarm module offers an exceptionally straightforward installation process, making it a versatile choice for a variety of wall types, ranging from solid brick walls to gypsum board and wooden panels. The mounting holes align perfectly with standard round European wall boxes commonly used for inset mounting, eliminating the need for separate product versions as it features a two-in-one enclosure. The choice is yours - whether to discreetly "hide" the module within the wall or mount it on the surface. Everyday tools like screwdrivers and pliers, along with basic knowledge and dexterity, are all that's required to install your module.
Simplified wiring
This unit streamlines the wiring process by incorporating spring clamp terminal blocks, offering a time-saving alternative to the more commonly used screw clamp terminal blocks. The spring-loaded clamps on these terminal blocks securely grasp the wires. Wires can be inserted directly into the terminal by applying downward pressure on the spring-loaded clamp, typically using a flathead screwdriver. This clamp securely holds the wire in place, establishing a robust electrical connection. These terminal blocks expedite the installation of wires and ensure a strong, reliable electrical connection thanks to the spring mechanism, which consistently maintains pressure on the wire, preventing any risk of it coming loose. This approach not only simplifies the installation process but also ensures a dependable electrical connection.
Directly connect to the mains
This is a Sentera -8 article version, which denotes devices operating on 230 VAC. Because 230 VAC allows for more efficient transmission of electrical power over long distances, it is the standard voltage for residential and commercial power distribution. It also reduces energy loss during transmission. 230 VAC powered systems have lower susceptibility to electromagnetic interference and noise, which can improve the performance of sensitive electronic equipment. But before all, not only does standardizing on 230 VAC simplify device design and compatibility, but it also does not require power transformers and converters. This means you will not need an external power supply module to provide lower current to the ALFC8 and you connect the module directly to the electricity network.
Communication via Modbus RTU
The alarm module features Modbus RTU communication. This means configuration can be fine-tuned using Modbus RTU. The Modbus register map offers a comprehensive view of all customizable settings. HVAC alarm systems employing Modbus technology can seamlessly connect with other Modbus-compatible devices and systems, such as controllers and gateways. This integration fosters smooth communication and collaboration between various elements of the HVAC system, thereby improving the overall monitoring and control functionalities. However, in case you decide not to use this feature, the module can work using its default settings.
