The Ei184 is a low voltage heat alarm with backup battery designed for use with suitable 8-30 volt control panels. The alarm has relay contacts (normally open and closed) for connecting to a panel and its associated devices.
The manufacturer's recommendation is to test the alarm by pressing the test button. This will simulate a heat input at the heat sensor. You can also test it with a hair dryer but make sure that the hairdryer is kept away at a suitable distance from the alarm. Do not attempt to test the alarm by using open fire or excessive heat as this may damage the unit.
