Product Description
Operation
The Ei405TY is an Optical Smoke Alarm powered by
long lasting lithium batteries designed to last the life of
the product. It is part of the RadioLINK range of RF
alarms. The RF signal will wirelessly interconnect the
Ei405TY to other RadioLINK products
The red indicator will flash every 40 seconds to
show that the detector has performed an automatic
self test
In normal standby mode the blue indicator will light
to indicate transmission of an RF signal
The Ei405TY uses advanced radio transciever
technology with unique software coding to transmit and
receive the radio signals. The transmissions are
frequency modulated (FM) and use Manchester coding
to ensure robust signal integrity and avoid signal noise
interference
In code mode, the blue indicator will flash to indicate
the number of other RF alarms that have been
“learned” in the system
The red indicator will flash rapidly to show an alarm
condition for the smoke detector
The RF range can be extensively improved by converting
the alarm into a “repeater” i.e. re-transmission of the RF
signals. The Ei405TY series alarms can be used as a
stand alone wireless interconnect system or be
The “Test/Hush” button will either silence false
alarms or perform a unit self test
In “Hush” mode the alarm enters a ten minute period
of reduced sensitivity and the red light flashes every
10 seconds and then resets
incorporated into existing home security systems
The Ei405TY 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 wireless interconnect up to twelve alarms
to allow all alarms to sound if just one of the
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)
interconnected alarms should be triggered.
The smoke detector will emit a beep and the red
light flashes every 40 seconds to indicate that the
battery is depleted and needs to be changed
The Ei405 has built in circuitry to aid suppression of
voltage transients and RF interference.
