Alarm add-on RF module Ei Electronics Ei413RF

The Ei Electronics Ei413RF is an RF add-on module that interfaces a RadioLINK alarm network with a security or fire panel. It operates at 868.499 MHz, supports multi-repeater multi-path RadioLINK communication and requires an 11–30 V DC supply, typically taken from the panel. The module decodes Fire, CO and Fault signals from RadioLINK devices and activates onboard relays to signal the connected panel; it can also transmit Fire Alarm signals to the RadioLINK system when triggered by panel inputs. The compact unit measures approximately 88 × 88 × 42 mm and provides a transmission range of up to 100 m in open conditions.

Advantages

The Ei413RF provides reliable wireless communication between Ei Electronics RadioLINK alarms and conventional panel systems using robust multi-repeater, multi-path RF technology. It supports both voltage-free (NO) contact wiring and DC voltage inputs for flexible integration with panel inputs, and it can be coded to the RadioLINK network to ensure correct device association. The module’s wide input voltage range (11–30 V DC) and compact dimensions simplify installation in many panel environments.

Suitable for

• Integrating Ei Electronics RadioLINK smoke, heat and CO alarms with a conventional fire or security panel
• Retrofit projects where wireless alarm signalling to/from a panel is required
• Installations needing flexible input options (NO contacts or DC input) for panel-triggered wireless alarms

How to use

Mount the Ei413RF so that its RF signal path remains robust and unobstructed; avoid placing the unit inside metal enclosures or locations where RF attenuation could be significant. Connect the module to an 11–30 V DC supply, normally taken from the panel, and wire the onboard relays or DC input to the panel input terminals according to the panel manufacturer’s end-of-line (EOL) termination requirements. Code the Ei413RF to the RadioLINK devices in the system so it can decode Fire, CO and Fault signals and activate the appropriate relays. When the panel activates the configured inputs (Fire or Test), the module will transmit the corresponding wireless alarm to the RadioLINK network.

Usage recommendations

Pay close attention to the Ei413RF positioning during installation to ensure reliable RF coverage; do not install inside metal enclosures or where the RF path could be seriously attenuated. When configuring relay wiring so the panel indicates both Fire and Fault conditions, consult the panel manufacturer’s EOL termination details.
