FAQs (4)

Q. How do you wire in the Ei140/Ei160 series of smoke alarms?

A. To wire the units correctly you would use 2 core and earth cable to the first unit and 3 core and earth to the interconnected units. The alarms do not have to be earthed but a brass screw connector is provided so that the earth can be safety terminated.

Q. What type of electrical cable is required to carry the mains supply and trigger signal for the wired alarms?

A. For the mains supply of the first unit a 2-core earth cable would be sufficient. For the connection between the alarms a 3-core earth cable would be required

Q. Which smoke alarms have an auxiliary switched output to activate a remote sounder?

A. The Ei140 series or Ei160 series of detectors can be used with Ei167 remote sounder.

Q. How can we test the alarm to make sure it is working?

A. 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.
