Categories: ,

The Ei128R Relay switches upon receipt of an alarm signal from a suitable Ei Alarm. The electrically isolated contacts can be used for many applications such as signaling, turning on lights, strobes etc.

It is powered by 230VAC mains power supply. 

The Ei128R is designed to be used with mains powered Alarms. It can either be installed underneath an easifit base or it can be sited remotely using the cover provided for electrical safety.

The Ei128R Relay base must be interconnected via hardwire even if it is a single Alarm installation.

As supplied the relay operates continuously but can be easily adjusted to pulse condition. In continuous mode, the relay switches until it receives an alarm cancel signal. In pulse mode, the relay switches for 5 seconds only.


Important: Ei Electronics devices are not designed to fulfil the role of a critical component of a BS5839-1 system’s requirements such as sound pressure level in a property, or to form a necessary component of an evacuation or other life safety procedure.
