Smoke detectors Ei Electronics

Optical, 9V Lithium, 85 dB, RF 150 m, +5 dBm, 868.499 MHz, Ø 152 mm, White 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 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

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 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 interconnected alarms should be triggered.

The Ei405 has built in circuitry to aid suppression of voltage transients and RF interference.

- 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
- 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 “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
- 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 the red light flashes every 40 seconds to indicate that the battery is depleted and needs to be changed
