Technical Data Sheets
The following technical data sheets are available for this product:
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 interconnecting smoke alarms would be suitable to connect an upstairs landing, downstairs hallway and a kitchen?
A.The Ei 140 series with radio-interlink bases would be suitable for this application:
Ei168RC/141 ionisation: best for landings
Ei168RC/146 optical: best for hallway, living rooms etc
Ei168RC/144 heat detector: best for kitchen and garage
Alternatively the Ei160 series (again with radio-interlink bases):
Ei168RC/161RC ionisation: best for landings
Ei168RC/166RC optical: best for hallway, living rooms etc
Ei168RC/164RC heat detector: best for kitchen and garage
There are also battery operated radio-interlinked smoke alarms available (See Ei3100RF and Ei600RF series)
Q.Do I need an ionisation or optical smoke alarm?
A.We recommend using an optical alarm in hallways, as these are less likely to go off because of cooking fumes from a connected kitchen. With landing areas we would recommend an ionisation alarm, as they are slightly quicker at detecting fast-flaming fires that would cover a small area quite quickly. Bedrooms and living rooms we recommend optical alarms for. And always remember to install heat alarms in a kitchen or garage.
Q.Can I link a CO detector with a Ei140 smoke alarm?
A.Yes, we recommend the Ei261EN. You should also install a Ei159 locator to allow you to find out if the alarm was triggered by CO gas or by fire.
