Product Description
The Ei146 is an Optical Smoke Alarm that runs on 230V
AC mains power, and has a 9V alkaline battery back up
in the event of mains failure. The 9V battery will last for
up to 4 years in standby mode, and capable of powering
the smoke detector for up to 2 years in the event of
mains failure.
The Ei146 is supplied with the Easi-Fit base that allows
very quick and simple installation of the smoke alarm,
combined with simple detector head removal and
replacement. The Easi-Fit base automatically connects
both mains power and battery as the detector head
slides on to the Easi-Fit base.
The Ei146 has other advanced features such as high
performance optical chambers fitted with integral insect
screens to reduce the chances of false alarms, as well
as the ability to interconnect up to twelve alarms to allow
all alarms to sound if just one of the interconnected
alarms should be triggered.
The Ei146 has built in circuitry to aid suppression of
voltage transients and RF interference to further reduce
the chances of false alarms under such conditions.
Operation
The green indicator will illuminate to show mains
power is present
The red indicator will flash every 40 seconds to
show that the detector has performed an automatic
self test
The red indicator will flash rapidly to show an alarm
condition for the smoke detector
The “Test/Hush” button will either silence false
alarms or perform a unit self test
In “Test” mode the alarm will perform a self test and
sound the horn
In “Hush” mode the alarm enters a ten minute period
of reduced sensitivity to overcome false alarm
conditions, and will then automatically reset itself
When interconnected to other Ei mains powered
alarms, an alarm on one detector will trigger all other
interconnected alarms within one second (only the
triggered alarm will flash a red indicator)
The smoke detector will emit a beep and flash the
red light every 40 seconds to indicate that the
battery back up is depleted and needs replacing
