Ei Professional Smoke Alarms and Smoke Detectors

Radio Frequency Alarms

Applications

The Ei408 Switched Input Module is designed for use with the RadioLINK range of smoke alarms and bases. The Ei408 is a RadioLINK interface module that accepts a Volt-free switched input from a hard-wired set of contacts (e.g. flow switch contacts on a sprinkler system) and sends out a corresponding RadioLINK alarm signal.

Visual RF transmission and power indicator

Powered by built-in Lithium cells

Unique House-Coding

Low battery power warning

RF performance to EN 300220-3

EMC performance to EN 301489-3

5 year guarantee

Installation

For full Installation and Siting Instructions please refer to the Use and Care Manual

Remove the front plate of the Ei408 by unscrewing the two screws and then fix the back-box to a solid surface using the screws provided. (Do not recess mount the back-box).

Neatly run wiring from the Volt-Free switched contacts that will be used to trigger the Ei408 through one of the knockouts in the backbox and connect to the terminal block.

Switch on the built-in battery by sliding the yellow battery switch to the “on” position.

Press and hold the House Code button until the red light on the front plate of the Ei408 illuminates solidly. As soon as the light illuminates, release the House Code button. The red light should start to flash slowly (this indicates that the Ei408 is sending out its own unique House Code signal).

Screw the front plate back onto the back-box.

As quickly as possible put all other RadioLINK devices that are part of the system into House Code mode (see individual instruction leaflets). This must be done within 15 minutes of putting the Ei408 into House Code mode.

Check that the number of amber light flashes (for RadioLINK bases) or blue light flashes (for RadioLINK alarms) corresponds to the number of RadioLINK devices in the system. For example, with 3 Ei168RC RadioLINK bases and 1 Ei408 Module in the system there should be 4 amber light flashes on each Ei168RC base (Note: The red light flashes from the Ei408 do not relate to the number of RadioLINK devices. The flashes simply show that it is sending out its own unique House Code).

Remove the Ei408 from House Code mode by unscrewing the front plate and then pressing and holding the House Code button until the red light illuminates solidly. As soon as it illuminates solidly, release the House Code button. The red light should stop flashing. Re-fit the front plate back onto the back-box. (Note: The Ei408 will automatically exit house Code mode after 15 minutes from it initially being put into House Code mode, so this step may not be required).

Remove all other RadioLINK devices from House Code mode (see individual instruction leaflets).

Trouble Shooting

If, when checking the RadioLINK interconnection, some of the alarms do not respond to the Ei408 test then:
Ensure the Ei408 has been activated correctly and the red light has come on continuously for 3 seconds and then continues to flash red every 20 seconds.

Ensure that there is an Alarm/Base set as a “Repeater” within a few metres of the Ei408. If Ei168RC RadioLINK Bases are being used, they are set as “Repeaters” as standard and so an additional base (with alarm) may need to be installed. If Ei405 and/or Ei405TY
RadioLINK Smoke Alarms are being used, set the alarm that is closest to the Ei408 into “Repeater” mode.

There are a number of reasons why the radio signals may not reach all the RadioLINK units in your system.

Try rotating the units or relocating the units (e.g. move them away from metal surfaces or wiring) as this can significantly improve signal reception.

Rotating and/or relocating the units may move them out of the range of existing units even though they may have already been House Coded correctly in the system. It is important therefore to check that all units are communicating in their final installed positions. If units are rotated and/or resited, we recommend that all units are returned to the factory settings (see their respective use and care instructions). Then House Code all units again in their final positions. The radio interconnection should then be checked again.
