Surface Mount Kit which includes Ei128R and Ei128COV with 5 Amp Relay - Ei128C

The Ei140 and Ei3000 series of detectors are mains powered with a back up battery. For a kitchen area, it is recommended to install a heat detector as opposed to a smoke detector. This is because the heat detector is activated when the temperature inside the room reaches approx. 57°C, therefore it does not sound falsely when cooking fumes are present. When installing a heat detector, please note that this should be fitted centrally in the room and not directly above any cooking appliances. The steam from pans, kettles and toasters is hot and could activate the detector if it was installed directly above them. To connect the heat detector to an external device, you would need to use an Ei128R surface mount with 5 Amp relay. When the heat detector is triggered, the Ei128R signals ancillary devices.
