Applications

The new Ei 405TY series of RF Smoke Alarms using 10 year+ lithium battery technology is designed to facilitate easy installation and to provide maintenance free operation (no battery replacement). Proven and trusted Ei Smoke Alarm technology is incorporated in a new profile alarm that is quick and easy to install and interconnects without wiring.

The 405 series RF Smoke Alarms can be used as a stand alone wireless interconnected system or be incorporated into existing Home Security Systems to provide Fire as well as Security Safety.

Installation

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

Select a location complying with the advice in the use and care manual

Remove the mounting plate from the Smoke Alarm

Place the base on the ceiling/wall exactly where you want to mount the unit. With a pencil, mark the location of the two screw holes

It may be necessary to rotate/resite units to maximise the radio link signals. Consequently we advise to use only one screw initially. Taking care to avoid any electrical wiring in the ceiling, drill one hole through the centre of one of the marked locations. Push the plastic screw anchors provided into the drilled hole. Screw in firmly. The second screw may then be used to securely fix the alarm in place after the radio link interconnection is verified

Slide the Alarm onto the Mounting Plate – this action switches on the unit

Carefully line up the unit on the base and slide on

Press the test button on each alarm to ensure that the smoke alarm works

Check the radio link interconnection by holding the test button down until the blue light has come on continuously – this indicates that the alarm is now transmitting radio link signals. You should now be able to hear the other alarm(s) in the distance. If you do not hear the other alarm(s) then you may need to rotate/resite the alarm

The units, as received, will transmit and receive the default RF signal. However, to avoid other neighbouring systems interfering with your alarms, we recommend that you “house code” your alarms

Trouble Shooting

Alarm sounds for no apparent reason:

House code your alarms. If the alarms are in the default factory settings, neighbouring units may cause them to alarm

Check for fumes, steam etc. from the kitchen or bathroom. Paint and other fumes can cause nuisance alarms

Check for any sign of contamination such as cobwebs or dust. Clean the alarm as described in use and care manual

Press the test/hush button on the unit causing the alarm (this can be identified as the alarm with the red light flashing rapidly) – this will silence the smoke alarm for 10 minutes and also silence all other smoke alarms in the system

If you have a remote control keyfob (Ei410), press the locate button to identify the source of the alarm. This alarm(s) should then be checked for any faults

The Alarm Fails to Sound When The Test Button is Pressed:

Check the age of the unit – see the “replace by” label on base of unit

Check the battery snaps are firmly connected on the Ei405 model

On the Ei405TY model ensure the unit is pushed fully home on the mounting plate, as this connects the battery. If necessary, the unit should be removed from the mounting plate and the battery switch moved to the “ON” position

The Alarms Sound but the Wireless Interconnection does not work:

There are certain limitations on radio frequency signals and so, some alarms may not sound when the test button of a smoke alarm and/or a remote control keyfob (Ei410) is pressed. Then;

Ensure you have held the test button down until the blue light has come on continuously (this could take up to 5 seconds)

House code all smoke alarms as described in the use and care manual (section 6)

Convert a centrally located smoke alarm into a “repeater” unit – this effectively boosts the signal strength between the units

Rotate and/or resite the units – the signal strength may not be sufficient due to the distance and/or the number of walls/ceilings between the units
