RECOMMENDED LOCATIONS

Figure 2 illustrates where Smoke Alarms and Heat Alarms should be located in a typical two storey house. Note the spacings in “Recommended Protection” which ensure theearly detection of fire and the warning will be heard.

Locate Heat Alarms in rooms adjoining or on escape routes kitchens, garages, boiler houses etc. where Smoke Alarms are unsuitable. Install within 5.3m (17 feet) of potential sources of fire.

overheated PVC wiring etc). An Ionisation Alarm should be located upstairs to detect fast flaming fires (e.g. paper burning in a container or a greasefire inthe kitchen) which couldrapidly block the main escape route.

Checking you can hear the Smoke & Heat Alarms

With the Alarm sounding in its intended location, checkyou are able to hear it in each bedroom with the door closed, above the sound of the radio.The radio should be set to areasonably loud conversation level. If you can’t hear it over your radio the chances are that it wouldn’t wake a person.

If a Smoke Alarm is too far away for it to wake a person, it is best to interconnect to another Smoke Alarm or Heat Alarm near the bedroom, so when one alarm senses fire, all interconnected alarmsrespond (see below for furtherdetails).

LOCATIONS TO AVOID

Don’t place Smoke Alarms in any of the following areas:

Bathrooms, kitchens, shower rooms, garages or other

• rooms where the smoke alarm may be triggered by steam, condensation, normal smoke or fumes. Keep at least 6 metres (20 feet) away from sources of smoke.

Don’t place Heat Alarms in any of the following areas:

Bathrooms, shower rooms or other room where the unit

• may be triggered by steam or condensation.

Don’t place Smoke or Heat Alarms in any of the following areas:

Places where the normal temperature can exceed 40°C

• (104°F) or be below 4°C (39°F) e.g. attics, furnace rooms etc. directly above ovens or kettles, as the heat/steam could cause nuisance alarms.

Near a decorative object, door, light fitting, window

• moulding etc., that may prevent smoke or heat from entering the 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 or heat 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 (eg. over stairwells) where it

• may be difficult to reach the alarm (for testing, hushing or battery replacement).

• Locate away from very dusty or dirty areas as dust build-up in the chamber can impairperformance. It can also block the insect screen mesh and prevent smoke from entering the

INTERCONNECTING SMOKE/HEAT

ALARMS

When a fire is sensed the alarm must be given throughout the house. Up to twenty (20) Smoke Alarms (models EI 180, 181, 185, 186 only) and Heat Alarms (model EI 183, 184 only) can be interconnected so that when one senses fire all alarm. Caution: Do not interconnect to any other type of alarm. The unit initiating the alarm can be identified by the red LED on the cover flashing every second. Figure 6 shows the interconnect wiring.

Note: It is only necessary to wire one relay to thecontrol panel. If any alarm senses fire this relay will change state due to the signal on the interconnect line.

These Alarms should be interconnected only within the confines of a single family living unit. If they are interconnected between different units there may be excessive nuisance alarms. Everybody may not be aware that they are being tested or that it is a nuisance alarm caused by cooking etc. When one unit alarms all relays will switch.

Installation

Select a location complying with the above advice.

1. Remove the mounting plate from the Smoke Heat Alarm by releasing the tamper-proof catch with a small screwdriver as shown in figure 1a and sliding the alarm from the plate.

2. Lift the foam flap covering thecircuit on the mounting plate. If necessary move the jumpers on S1 and/or S2 (see figure 7) by carefully lifting them and placing them over the required pins.

3. If surface wiring the unit remove the required breakaways. Low voltage signal cable is satisfactory (e.g. wire 0.22mm provided the resistance between the units and the panel is less than 20 ohms.

All wiring must comply with local codes. Connect the wires to the terminals as shown in the wiring diagram (figure 6). The gasket flap can be tucked behind the terminals while this is being done. Place gasket flap back over circuit board and terminals.

LOCATING ALARMS

SMOKE ALARMS

Sufficient smoke must enter the Smoke Alarm before it will respond. The Smoke Alarm needs to be within 7.5 metres (25 ft) of the fire to respond quickly. It also needs to be in a position where its alarm can be heard throughout your home, so it can wake the occupants in time for 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, (apart from kitchens, bathrooms etc. see Locations to Avoid).

A Smoke Alarm should be located between the sleeping area and the most likely sources of fire (living room or kitchen for example). It should not be more than7.5 metres (25 ft) from the door to any room where a fire might start on the escape route from the house.

Important: These Smoke/Heat Alarms are designed for a single occupancy in a residential type environment.

A Smoke Alarm should be sited within 3m of bedroomdoors for improved audibility.

HEAT ALARMS

The Heat Alarm gives a fire warning when the temperature at the unit reaches 58°C. It is ideal for kitchens, garages, boiler houses and other areas wherethere are normally high levels of fumes, smoke or dust i.e. places where Smoke Alarms cannot be installed without the risk of excessive nuisance alarms.

A Heat Alarm should only be used in a room adjoining an escape route, inconjunction with Smoke Alarms onthe escape routes.

All the Heat Alarms and Smoke Alarms should be interconnected to ensure the early warning will be heard, particularly by somebody sleeping. A properly designed early warning fire system ensures the alarm is given before the escape routes become blocked with smoke. Therefore, there must be Smoke Alarms along the escape routes as Heat Alarms would not give sufficient warning. However, a fire in a closed room (e.g. kitchen) adjoining the escape route, can eventually cause the corridor to become smoke-logged due to smoke leaking out from around the door before adequate warning can be given by detectors in the corridor. (Smoke leaking out from a room is often cool and slow moving so it can take a long time to rise to the ceiling, and travel to a detector which could be some distance away). A Heat Alarm in the closed room will give early warning of fire in that room and help overcome this problem.

Single Storey Dwelling.

If the Home is on one level (a bungalow or mobile home for example) you should put the 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 aperson in the bedrooms. (for example, see figure 3) Single storey Dwelling with Recommended ProtectionSingle Storey Dwelling with Recommended Protection

BEDROOM

KITCHEN

Figure 3

BEDROOM BEDROOM

If the bungalow is very large and the corridor orhallway is more than say 15 metres (50 ft) long, one Smoke Alarm will not be sufficient. This is because no matter where it is locatedit will be more than 7.5 metres from potential fires.

In houses with more than one sleeping area, Smoke Alarms should be placed between each sleeping area and the living area.

DINING

Multi Storey Dwellings

If the dwelling has more than one storey it must have an interconnected alarm on each level for minimum protection.

Maximum Protection

For maximum 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). Ensure that they are all interconnected. The living room is the most likely place for afire 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.

Fire Authorities (including the Home Office, UK) recommend that both Optical and Ionisation Smoke Alarms should be fitted for the fastest response to all types of fires. An Optical Alarm should be located downstairs to detect slow smouldering fires (e.g. from a cigarette burning in a couch or bedding,

smoke detector chamber.

•

Locate the unit at least 1 metre (3 feet) from dimmer controlled lights and wiring - some dimmers can cause interference.

•

Locate unit at least 1.5m (5 feet) and route wiring at least 1m (3 feet) away from fluorescent light fittings as electrical “noise” and/or flickering may affect the unit.

•

Do not locatein insect infested areas. Smallinsects getting into the smoke detector chamber can cause intermittent alarms. Insects and contamination on theHeat Alarm sensor can increase its response time.

POSITIONING SMOKE/HEATALARMS

The locationsmust comply with applicable buildingregulations.

Hot smoke rises andspreads out, so acentral ceiling position is the preferred location. The air is “dead” and does not move in corners, therefore Smoke & Heat Alarms must be mounted away from corners. Place the unit at least 300mm (12 inches) from any light fitting or decorative object which might obstruct smoke / heat entering the Alarm. Keep at least 300mm (12”) away from walls. See figure 4. (Smoke Alarms should be located directly on the ceiling or up to 570mm below it. Heat Alarms should be located directly on the ceiling or up to 90mm below it).

Wall mounting is not recommended for these Alarms.

Sloping Ceiling

In areas with sloping or peaked ceilings install your Smoke/Heat Alarm 90mm (3 feet) from the highest point measured horizontally (see figure 5), because “dead air” at the apex may prevent smoke from reaching the unit.

planned to ensure nuisance alarms are not excessive, e.g. from cooking or weekly testing.

Smoke Alarm Locator Switch (EI 159) should be incorporated into the system and be readily accessible to all occupants so that the source of an alarm can be quickly identified. (see Accessory section).

All Alarms must be cleaned and maintained regularly.

A competent person must be on call to quickly remove any faulty alarms (i.e. units with red light flashing), which are causing all alarms to sound.

INSTALLING SMOKE/HEAT ALARMS

The Alarm is designed to be permanently mounted , using it’s own built-in terminal blocks to connect it to the panel. The mounting plate can be screwed directly to the ceiling after connecting the wires.

IMPORTANT PRECAUTION: Do not install the actual alarm itself in new or renovated buildings until all work is completed (including floor coverings)and the building has been fully cleaned. The wiring can be installed when appropriate. (Excessive dust and debris from building work can contaminate the smoke chamber or heat sensor and cause problems, it will also invalidate the guarantee). If it must be installed, cover it completely, particularly around the edges, with a dust cover (eg. with the elasticated cover supplied or a plastic bag), until all cleaning is finished.

Warning: Wiring should only be installed by an Electrician in

accordance with current IEE wiring regulations for electrical installation. The installation must also be in accordance with the controlpanel instructions and the instructionsin this leaflet.

Warning: The mains circuit used to power the control panel must be a 24 hour voltage circuit and be wired on a separate circuit (one with no other lights or applilances) to ensure maximum reliability of the supply.

Warning: The Alarms must be connected to a panel that supplies a permanent voltage that cannot be switched off.

Warning: For safety reasons the voltage supply from the control panel must not be greater than 30V (peak or d.c.) and must beeither independent of the supplymains or isolated from it by double or reinforced insulations.

Warning: If the control panel is not provided with an ALL-POLE MAINS SWITCH (with a contact specification of at least 3mm in each pole), then the electrical installation of the building shall incorporate an ALL-POLE MAINS SWITCH, (with a contact separation of at least 3mm in each pole).

of the hole inthe ceiling. This is to prevent airdraughts affecting the smoke / heat entering the alarm. If the orifice is too large it should be sealed with silicone rubber or equivalent.

Check the battery is connected in the back of the alarm ( EI 181, 184, 186 only).

Carefully line up the unit on the base and slide on.

Press the test/hush button for 10 seconds. The horn should sound (EI 181, 184, 186 only).

7. Connect the panel power tothe alarm circuit. The green light on the mounting plate should turn on.

Check the operation of the Alarm as outlined in the next section.

CHECKING AND MOUNTING YOUR

ALARMS

INSPECTION & TESTING PROCEDURE

After installation, after re-occupation following a holiday, and weekly, check all your Alarms as follows:

Check the green light is illuminated on the mountingplate. This shows the panel is supplying power.

Press the test button for up to 10 seconds to ensure the sensor chamber, electronics and sounder are working. A red light on the cover will flash while horn is sounding. The relay contacts should change over with the EI185, EI186 relay contacts when the horn sounds with the EI180, EI181, EI183, EI184, it contacts within 6 seconds after the horn sounds. The alarm will stop when the button is released. Pressing the test button simulates the effect of smoke or heat during a real fire and is the best way to ensure the Alarm is operating correctly.

WARNING: DO NOT TEST WITH FLAME.

This can set fire to the Alarm and damage the house.

We donot recommend testing with smoke or heatas the results can be misleading unless special apparatus is used.

Check for any sign of contamination such as cobwebs or dust and clean the alarm as described below if necessary.

Interconnected alarms

Test the first unit by pressing the button. All the detectors should alarm within about 5 seconds of the first horn sounding and the red light on the first unit only will flash once a second. The relay contacts should change over about 6 seconds after the horns sound. Check all the other units similarly. (Note: Ionisation and Heat alarms signal to other interconnected alarms, about 4 seconds after their own horn sounds. Optical alarms signal within about a second).

Checking Battery Back-up

The Alarm automatically monitorsthe battery every 40 seconds to ensure thatit is satisfactory. If itis depleted it will givea short beep every 40 seconds (models EI 181, EI 184 and EI 186 only).

Before replacing the battery, check that the beeps are not due to one of the following:

(i) Battery snaps not connected properly.

(ii) On the Optical Smoke Alarms only (EI 186/185) if the unit beeps and the red light does not flash at the same time it indicates a problem with the smoke chamber – see Cleaning the Smoke Alarm section below:

If the beeps have continued for over 20 minutes (and the other causes of beeps have been ruled out – see below) the battery must be replaced.

(iii) Switch off the panel voltage supply and remove the unit as shown in fig 1a.CAUTION: Donot attempt to remove the Alarm without first releasing thetamper clip. Remove depleted battery and replace with one of the specified 9V alkaline batteries. The alarm cannot be replaced on the mounting plate unless a battery is installed. After replacing the battery, slide on to the mounting plate and then press the test button and ensure horn sounds loudly before you turn on the panel supply. Note: Only use the specified Alkaline batteries shown on the base label (Duracell MN1604, Eveready 522 or Energizer 6LR61). We recommend that the “use by date” on the battery should still have at least 2 years to go. Older batteries will give beeps prematurely.

We recommend that the battery is replaced each year for optimum performance.

Please note: The ionisation and heat alarms (EI 180, 181,183 and 184) give two short beeps about a second apart at the end of the hush period (i.e. about 10 minutes after test/hush button has been pressed). These two beeps should not be confused with low battery beeps.

Manual Testing

We recommend that the functioning of the battery back-up is checked after installation and then at least yearly as follows:-

Turn off (or disconnect) the power at the panel (green light on mounting plate should be off) press the test button and ensure the horn sounds loudly for 10 seconds. (This checks the battery back-up models EI 181, EI 184 and EI 186 only).

Note: A good battery can supply the unit for over a year in standby (or 5 hours in alarm) without panel power.

In standby, with panelpower, the battery can operate for upto 4 years before the low battery beeps start – these will normally

If there are frequent nuisance/falsealarms it may be necessary to re-locate thedevice away from the sourceof the fumes. If for some reason the alarm continues to sound without smoke or heat being present (due to insect infestation or contamination build-up for example) the units can be silenced by disconnecting the mains power and removing the unit (see figure 1). If cleaning the Alarm does not correct the problem it can be returned to the manufacturer for repair or replacement (see Getting Your Alarm Serviced below).

Hush Feature

All the Smoke / Heat Alarms have a combined Test/Hush Button to help you control nuisance false alarms.

1. To cancel a false alarm, press the Test/Hush Button located on the cover. The Alarm will automatically switch to a reduced sensitivity condition (very large levels of smoke from a nearby fire will override the Hush on the smoke alarms).This condition allows unwanted alarms to be silenced for a period of approximately 10 minutes.

The unit will flash the red light every 10 seconds (instead of the normal 40 seconds) to indicate the sensitivity is reduced. At the end of the hush period the Ionisation Smoke Alarm (EI 181/180) andthe Heat Alarms (EI 184/183) will give two short beeps. The Optical Smoke Alarm (EI 185/186) does not give these two beeps.

On interconnected Alarms, pressing the Test/Hush Button on the one sensing smoke (i.e. the one with the red light flashing every second) will silence all alarms. Pressing the Hush Button on any other Alarm will not cancel the alarm.

2. The unit will reset to normal sensitivity at the end of the silenced period. If additional silenced time is required, simply push the Test/Hush Button again.

IMPORTANT SAFE GUARDS

When using household protective devices, basic safety

• precautions shouldalways befollowed, including those listed below:

Please read all instructions.

•

Rehearse emergency escape plans so everyone at home

• knows what to do in case the alarm sounds. Further information can be obtained from the Home Office Publication entitled “Smoke Detectors in the Home” (FB2) or from your local fire prevention officer.

NOTE: Constant exposure to high or freezing temperatures

• or high humidity may reduce the life of the battery.

To maintain sensitivity to smoke, do not paint or cover smoke

• /heat alarms in any manner; do not permit any accumulation of cobwebs, dust or grease.

4. Call the Fire Brigade from a neighb our’s house. Remember to give your name and address.

5. NEVER re-enter a burning house.

LIMITATIONS OF SMOKE HEAT ALARMS

Smoke/Heat Alarms have significantly helped to reduce the number of fire fatalities in countries where they are widely installed.

However independent authorities have stated that they may be ineffective in some circumstances. There are a number of reasons for this:

The Alarms will not work if the mains power is off and the

• back-up battery is depleted. On the EI181/184/186 alarms the batteries should be replaced annually and when the unit gives low battery beeps.

Smoke/Heat Alarms will not detect fire if sufficient smoke/

• heat does not reach the alarm. Smoke/Heat may be prevented from reaching the Alarm if the fire is too far away, for example, if the fire is on another floor, behind a closed door, in a chimney, in a wall cavity, or if the prevailing air draughts carry the smoke/heat away. Installing Smoke/Heat Alarms on both sides of closed doors and installing more than one Smoke/Heat Alarm as recommended in this leaflet very significantly improves the probability of early detection.

The Alarm may not be heard.

•

A Smoke / Heat Alarm maynot wakea person who hastaken

• drugs or alcohol.

Smoke / Heat Alarms may not detect every type of fire to give

• sufficient early warning. Theyare particularly ineffective with: fires caused by smoking in bed, escaping gas, violent explosions, poor storage of flammable rags and/or liquids, (for example petrol, paint, spirits etc), overloaded electrical circuits, arson and children playing with matches.

Fire Authorities (including the Home Office, UK) recommend

• that both Optical and Ionisation Smoke Alarms should be fitted for the fastest response to all types of fires.

Smoke / Heat Alarms don’t last indefinitely. For example if

• there is a build up of contamination, performance will be impaired.

The manufacturer recommends replacement of the Smoke/ Heat Alarms after 10 years as a precaution.

TROUBLESHOOTING

1. FREQUENT NUISANCE ALARMS OCCUR:

(1) Close kitchen / bathroom door when in use.

(2) Ensurethat the alarm is sited at least6m away from sources of fumes.

(3) Contamination from insects, paint or paint fumes may have occurred. Clean the alarm as described in this booklet.

(4) If the problem persists, resiting of the unit should be considered. Alternatively, replace the unit with an Optical unit (EI186/185), assuming that the problem is with an Ionisation type alarm (EI181/180).

2. ALARM SOUNDS FOR NO APPARENT REASON:

(1) Identify the alarm source. On interconnected units, the red light on the cover will flash rapidly only on the unit which is the source of the alarm.

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

(3) Press the test/hush button to silence the Smoke/Heat Alarm for 10 minutes.

(4) If alarm does not stop, remove the unit (see figure 1). (Only remove alarm with red light flashing, the others are probably satisfactory).

3. LOW BATTERY BEEPS:

(On EI 181/184/186 only)

If the battery is correctly connected and the unit has beeped for over 20 minutes the battery is probably depleted. Obtain a new battery, remove the alarm and replace the depleted battery. (see figure 1).

OTHER BEEPS:

(1) If the panel is providing power and replacing battery or cleaning unit has not stopped beeps, a fault may exist. Replace the unit (see figure 1).

(2) The Ionisation/Heat units (EI 181/180/184/183) give two beeps 10 minutes after the test/hush button is pressed.

(3) If the Optical units (EI 186/185) beep without the red light flashing at the same time, the chamber is defective. Clean the chamber.

4. INTERCONNECTED ALARMS DO NOT ALL SOUND AND THE RELAY DOES NOT SWITCH:

(1) Hold test button for 10 seconds after first alarm has sounded to ensure signal is transmitted to all units. Relay should switch.

(2) Checkthat the green power lighton the mounting plate ison.

(3) Check panel and wiring.

last for over 30 days before the battery is fully depleted.

CLEANING YOUR ALARM

Clean your Alarm regularly, particularly in dusty areas. Use the narrow nozzle attachment of your vacuum cleaner to remove dust, insects and cobwebs from the sides and cover slots where thesmoke or heat enters. Toclean the cover, wipe with a damp cloth. Dry cover thoroughly with a lint free cloth.

WARNING: Do not paint your Alarm.

Other than the cleaning described above, no other customer servicing of this product is required. Repairs, when needed, must be performed by the manufacturer.

All Alarms are prone to dust and insect ingress which can cause false alarms or failure to alarm.

The latest design, materials and manufacturing techniques have been used in the construction of our Alarms to minimize the effects of contamination. However it is impossible to completely eliminate the effect of dust and insect contamination, and therefore, to prolong the life of the Alarm you must ensure that it is kept clean so that excess dust does not build up. Any insects or cobwebs in the vicinity of the Alarm should be promptly removed.

In certain circumstances even with regular cleaning, contamination can build up in the smoke sensing chamber causing the alarm to sound or fail. If this happens the alarm must be returned to us for servicing or replacement. Contamination is beyond our control, it is totally unpredictable and is considered normal wear and tear. For this reason, contamination is not covered by the guarantee and a charge is made for servicing such units.

If you experience persistent false alarms, in particular locations, due to contamination of the smoke chamber you could consider replacing Optical Smoke Alarms (EI 186/185) with Ionisation Smoke Alarms (EI 181/180). Ionisation type alarms are less susceptible to dust than Optical type alarms.

NUISANCE ALARMS

If there is a nuisance alarm simply press the test/hush button on the Alarm to silence the unit for 10 minutes.

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 a unit has been damaged in any way or does not function properly,do not attempt a repair. Return Alarm (see - Getting your Alarm Serviced).

•

This appliance is only intended for premises having a residential type environment.

•

Smoke / Heat Alarms are not a substitute for insurance. The supplier or manufacturer is not your insurer.

•

The chamber inside the Ionisation Smoke Alarms (EI 181/180) contains a small amount of radioactive material. Do not tamper with the chamber. You may safely install and clean the Smoke Alarm following this leaflet’s instructions.

•

In the United Kingdom Ionisation Smoke Alarms can be disposed of in normal household refuse, but due to the tiny amount of radioactivematerial contained in the unit,no more than one alarm per dustbin.

•

In the Republic of Ireland Ionisation smoke alarms should be returned for disposal to thenearest address at the end of this leaflet.

Do not dispose of your Alarm in a fire.

Use the Smoke / Heat Alarm Test Buttons to familiarize your family with the Alarm sound and to practice fire drills regularly with all family members. Draw up a floor plan that will show each member at least 2 escape routes from each room in the house. Children tend to hide when they don’t know what to do. Teach children how to escape, open windows, and use roll up fire ladders and stools without adult help. Make surethey know what to do if the alarm goes off - see next page.

ALARM GOES OFF

1. Check room doors for heat or

smoke. Do not open a hot door. Use an alternate escape route. Close doors behind you as you leave.

2. If smokeis heavy, crawl out, staying

close to floor. Take short breaths, if possible, through a wet cloth or hold your breath. More people die from smoke inhalation than from flames.

3. Get out as fast as you can. Do not

stop for packing. Have a prearranged meeting place outside for all family members. Check everybody is there.

ACCESSORY

Smoke Alarm Locator EI 159:

The Smoke Alarm locator is recommended for systems with three or more Smoke / Heat Alarms as it helps quickly identify the unit in alarm and reduces the impact of nuisance alarms.

Pressing the Smoke Alarm Locator button will silence all interconnected alarms for 10 minutes, except those sensing fire. It is easily installed between the interconnect and 0 volt terminals.
