Enhanced Integration with Safety and Building Systems

The Ei128R is designed to bridge your alarm system with external life-saving or automation devices. As soon as any alarm in the interconnected system is triggered, the module receives the signal via the hard-wire interconnect and activates its relay output. This can be connected to a wide range of systems, such as:

for visual alerts (ideal for deaf or hard of hearing occupants)

or ventilation systems

for smoke compartmentation

or warden call systems in supported housing

This makes the Ei128R especially useful in multi-residential buildings, care homes, and commercial properties where additional fire safety equipment is required to respond automatically to alarm conditions.

Example Use Case: Assisted Living Apartment Integration

A residential care apartment fitted with Aico 3000 Series smoke and CO alarms requires integration with a telecare system to alert support staff in another unit. The Ei128R is installed beneath a hallway heat alarm and hard-wired to the telecare input. When any interconnected alarm activates, the Ei128R triggers the system remotely, ensuring staff are notified immediately. The relay is set to pulse mode to avoid prolonged system activation.

Simple Installation with Maximum Flexibility

Installation is quick and tidy thanks to the unit’s easi-fit base footprint, pre-drilled knockouts, and intuitive wiring block. You can mount it directly beneath a compatible Aico alarm or in a standalone location using the included Ei128COV cover. Switching between pulse and continuous modes is done via a manual internal selector switch, allowing for tailored response behaviour based on the connected system’s requirements.

The Aico Ei128R Hard Wired Relay Module (SKU: Ei128R) is a robust, cost-effective solution for adding external output control to your Aico fire and CO alarm system. With full compatibility across multiple Aico product ranges, dual-mode output, and high-capacity relay contacts, it offers professional-grade reliability and flexibility—ideal for use in homes, care facilities, and complex building environments where advanced safety integration is key.
