1. READ THIS FIRST

A Smoke Alarm is an early warning device. Used correctly it can give you and your family valuable extra time to escape.

¥ Models Ei405 & Ei405C - connect battery snaps firmly (see

fig 1b). Press the test button and horn should sound.

¥ Models Ei405C, Ei405TY & Ei405TYC - slide unit on to

mounting plate to connect the batteries.

¥ When the battery is first connected the Alarm may sound

for 2-3 seconds and/or the red light may flash quickly for 10 seconds - this is normal.

¥ A Smoke Alarm does not prevent fires.

¥ Install correctly, in the centre of the ceiling if possible.

¥ Test weekly.

¥ If the Alarm beeps without the red light flashing at the

same time then clean unit as this is the automatic test feature indicating the chamber is degraded.

¥ Plan your escape route.

¥ Proper protection usually requires more than one Smoke

Alarm.

¥ If you have any doubt or query about Smoke Alarms con-

sult the supplier or your local Fire Brigade.

¥ Models Ei405TY & Ei405TYC - When the Alarm beeps

and the red light flashes at the same time or the blue light flashes every 9 seconds it indicates the battery is depleted and the entire alarm must be replaced. This normally occurs after 10 years has elapsed.

¥ Models Ei405 & Ei405C - When the Alarm beeps and

the red light flashes at the same time replace the battery (see fig 1).

The wireless interconnect will operate as received once the batteries are connected.

(Program units if nearby systems are like-

ly to cause false alarms).

2. INTRODUCTION

Congratulations on purchasing Ei405 Radio Smoke Alarms. You can easily install these alarms throughout the house in closed rooms, corridors and in the attic for the fastest response to developing fires.

Closed doors are great for slowing down the spread of fire, but unfortunately they can also greatly slow down the response time of alarms, as they block the smoke getting to them. Without interconnection, closed doors also greatly reduce the alarm sound level throughout the house, so even though the fire is detected early, the alarm may not be heard.

The Ei405 Radio Smoke Alarms offer the comfort of interconnection without the hassle of installing the interconnect wires. The wireless interconnect helps ensure the alarm will be heard everywhere - including most importantly, the bedrooms.

The wireless interconnect will operate as received once the batteries are connected. To check operation, first connect all the batteries (see section 1) and then hold down the test button on the first unit until the blue light comes on continuously for 3.5 seconds. All the other smoke alarms will respond within 5 seconds. If there is any possibility of a neighbour having a similar system, you should program your units so your system will not cause his/hers to alarm or vice versa. This is easily done and only takes a few minutes- see below (section 6.3).

A remote control Ei410 is available to allow you to test and hush the alarms, without having to reach up to the smoke alarms on high ceilings. The remote control also has a "Locate" button to identify the unit causing the alarm - this is

excellent, particularly at night, as it rapidly identifies where the fire is located. This is ideal for larger systems as the disturbance in the house can be kept to a minimum e.g. no need to enter all the bedrooms to check to see if the red light is flashing rapidly.

3. LOCATING YOUR SMOKE ALARM

Sufficient smoke must enter your Smoke Alarm before it will respond. Your Smoke Alarm needs to be within 10 paces (7.5 metres) of the fire to respond quickly. The smoke alarms need to be in positions where they can be heard throughout your home, so they can wake you and your family in time for you all to escape. A single

Smoke Alarm will give some protection if it is properly installed, but most homes will require two or more to ensure that a reliable early warning is given. For maximum protection you should put individual Smoke Alarms in all the rooms where fire is most likely to break out. Your first Smoke Alarm should be located between the sleeping area and the most likely sources of fire (living room or kitchen for example). But it should not be more than 10 paces (7.5 metres) from the door to any room where a fire might start and block your escape from the house.

3.1 Single Storey Dwelling. If your Home is on one level (a bungalow or mobile home for example) you should put your first Smoke Alarm in a corridor or hallway between the sleeping and living areas. Place it as near to the living area as possible, but make sure you can hear it loudly enough to wake you in the bedroom. (for example, see figure 2).

If your bungalow is very large and the corridor or hallway is more than say 20 paces (15 metres) long, one Smoke Alarm will not be sufficient. This is because no matter where it is located it will be more than 7.5 metres from potential fires.

Figure 3: Single storey dwelling with separate sleeping

areas.

In houses with more than one sleeping area, Smoke Alarms should be placed between each sleeping area and the living area (for example, see figure 3).

3.2 Multi Storey Dwellings If your home has more than one floor, at least one alarm should be fitted on each level (see figure 4). The Ei405 Radio smoke alarms are ideal in this situation as they are automatically interconnected without wiring.

3.3 Recommended Protection For recommended protection you should put individual Smoke Alarms in all the rooms where fire is most likely to break out (apart from the locations to avoid, mentioned below). The living room is the most likely place for a fire to start at night, followed by the kitchen and then the dining room. You should also consider putting Smoke Alarms in any bedrooms where fires might occur, for instance, where there is an electrical appliance such as an electric blanket or heater, or where the occupant is a smoker. You could also consider putting Smoke Alarms in any rooms where the occupant is unable to respond very well to a fire starting in the room, such as an elderly or sick person or a very young child.

3.4 Checking you can hear your Smoke Alarm With the Smoke Alarm sounding in its intended location, check you are able to hear it in each bedroom with the door closed, above the sound of your Hi-Fi System. The Hi-Fi system should be set to a reasonably loud conversation level. If you can t hear it over your radio the chances are that it wouldn t wake you. These Wireless interconnect smoke alarms will help to ensure the alarm will be heard through-out the house.

4. POSITIONING YOUR SMOKE ALARM

4.1. Hot smoke rises and spreads out, so a central ceiling position is the recommended location. The air is dead and does not move in corners, therefore Smoke Alarms must be mounted away from corners. Place the unit at least 0.3m (1ft) from any light fitting or decorative object which might obstruct smoke entering the Smoke Alarm. Keep at least 0.3m (1ft) away from walls and corners. See figure 5.

4.2 Wall Mounting When a ceiling position is not possible (for example on a ceiling having exposed beams or joists, or built-in radiant heating) put the top edge of your Smoke Alarm between 15 and 30 cm (6 and 12 inches) below the ceiling. Keep at least 0.3m (1ft) from corners. (see figure 5).

4.3 On a sloping Ceiling In areas with sloping or peaked ceilings install your Smoke Alarm 0.9m from the highest point measured horizontally (see figure 6), because dead air at the apex may prevent smoke from reaching the unit.

4.4 Locations to Avoid Don t place your Smoke Alarm in any of the following areas:

¥ Bathrooms, kitchen, shower rooms, garages or other

rooms where the smoke alarm may be triggered by steam, condensation, normal smoke or fumes.

¥ Attics or other places where extremes of temperature may

occur (below 4¡C or above 40¡C).

¥ Near a decorative object, door, light fitting, window

molding etc., that may prevent smoke from entering the

Smoke Alarm.

¥ Surfaces that are normally warmer or colder than the rest

of the room (for example attic hatches, uninsulated exterior walls etc). Temperature differences might stop smoke from reaching the unit.

¥ Next to or directly above heaters or air conditioning

vents, windows, wall vents etc. that can change the

direction of airflow.

¥ In very high or awkward areas where it may be difficult to

reach the alarm for testing.

¥ Locate unit at least 1.5m away from fluorescent light fit-

tings as electricial noise and/or flickering may affect the

unit.

¥ Locate away from very dusty or dirty areas as dust build-

up in the chamber can make unit too sensitive and prone to alarm. It can also block the insect screen mesh and prevent smoke from entering the chamber.

¥ Do not locate in insect infested areas. Small insects get-

ting in to the chamber can cause intermittent alarms.

4.5 Nuisance/False Alarms If, when the alarm goes off, there is no sign of smoke, heat or noise to indicate that there is a fire, you should get your family into a safe place, before you start investigating.

Check the house carefully in case there is a small fire smouldering somewhere. Check whether there is some source of smoke or fumes, for example cooking fumes being drawn past the Smoke Alarm by an extractor.

If there are frequent nuisance/false alarms it may be necessary to re-locate the device away from the source of the fumes.

If you installed the smoke alarms as received and did not program them, you may be receiving an alarm signal from a neighbouring system. This can be easy rectified by house coding your alarms (see section 6.3).

Pressing the test & hush button on the smoke alarm sensing fire (i.e. with the red light flashing rapidly) will silence the alarm for 10 minutes. (Pressing the hush button on the optional Ei 410 Remote Control acts in the same way).

5. INSTALLING YOUR SMOKE ALARMS

1. Select a location complying with the above advice.

2. Remove the mounting plate from the Smoke Alarm by releasing the tamperproof catch with a small screwdriver as shown in figure 1a and sliding the alarm from the mounting plate.

3. 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.

4. Taking care to avoid any electrical wiring in the ceiling, drill holes through the centres of the marked locations. Push the plastic screw anchors provided into the drilled holes. Screw in firmly.

5. Connect the battery to the battery snaps as shown in figure 1b (models Ei405 & Ei405C only).

6. Carefully line up the unit on the base and slide on. (This connects the batteries in the Ei 405C, TY, TYC units.

Install all the other alarms similarly.

6. LOOKING AFTER YOUR SMOKE ALARMS

6.1 Manually Testing your Smoke Alarm

It is recommended that you test your Smoke Alarm at least weekly to be sure the unit is working. It will also help you and your family to become familiar with the sound of the Alarm.

When you press the test button it simulates the effect of smoke during a real fire. So, there is no need to test the Alarm with smoke.

Press and hold the Test Button until the alarm sounds (Figure 7). The alarm will stop sounding shortly after the button is released.
