Description
Complete your fire, smoke, and carbon monoxide alarm network with the Aico Ei428 RadioLINK Relay Module. This mains-powered relay module triggers external devices, such as a strobe light or telecare device, when alarms in the property activate.
Key Features:
- Mains Powered: Includes rechargeable lithium back-up.
- Easy Installation: Features additional trunking knockouts and an easi-fit base footprint.
- Wireless Connectivity: Connects wirelessly with all other Aico wireless interconnection products.
Compatibility and RadioLINK Technology
The Aico Ei428 RadioLINK Relay Module with 140RC series (using an Ei168RC RadioLINK base), 160e series (with an Ei100MRF RadioLINK+ module), and the Ei3000 series (using an Ei3000MRF SmartLINK module). Additionally, it connects with any RadioLINK-enabled carbon monoxide alarms.
Installation Features
The module includes additional trunking knockouts for easy installation and fits underneath the space of an easi-fit or RadioLINK base. If needed, a cover (Ei128COV) is available. The relay module can be configured to provide either a 230V output or a 24V output using an external 24V supply.
Operation of Ei428 RadioLINK Relay Module
When the module receives a RadioLINK signal from one of the alarms in the system, the relay contacts operate, sending a signal to the connected system. The indicator on the cover shows a constant green light when mains power is connected.
Technical Specifications
- Power Source: Requires a 230V AC mains power supply with a green LED indicating mains power presence.
- Battery Backup: Features built-in, tamper-proof, rechargeable Vanadium Pentoxide lithium standby cells, lasting at least 10 years and providing at least 2 months of operation during mains power failure.
- Compliance: CE marked for conformance to BS EN 60065:1998 (Electrical Safety), EN300220-1 V1.3.1 (2000-09) (RF Performance), EN301489 V1.4.1 (2002 08) (EMC), and 3rd party tested for electrical safety per Annex K of BS 5446: Pt.1:2000.
- Radio Frequency: Operates on the 868 MHz band, minimizing interference. The maximum range is approximately 30 meters, depending on building type.
