1. Basic Information about your Heat Alarm

A Heat Alarm is an early warning device. A system based on in terconnected Heat Alarms and Smoke Alarms, can give you and your family valuable extra time to escape.

Note:-

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

Test weekly with Test Button.

Replace alkaline battery yearly or when it beeps once a min

ute. When the power is first connected the Alarm may sound for

2-3 seconds - this is normal. A Heat Alarm does not prevent fires.

Plan your escape route.

Proper fire protection requires Smoke Alarms in addition to

Heat Alarms with all units interconnected. If you have any doubt or query about Heat Alarms consult

the supplier or your local Fire Brigade.

(3 feet) away for fluorescent light fittings as electrical “noise” and/or flickering may affect the unit.

In excessively dirty or dusty locations where contamination

build-up could slow down response.

2. Locating your Heat Alarm

The Heat Alarmgives a fire warningwhen the temperature at the unit reaches 58° C. It is ideal for kitchens, garages, boiler houses and other areas where there 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, in conjunctionwith 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 Heat Alarm installed in a closed room will give early warning of fire in that room. A properly designed early warning fire system ensures the alarm is given before the es cape 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 leak ing 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).

Figure 1 illustrates where Heat Alarms and Smoke Alarms should be located in a typical two storey house. The following gives the recommended spacings tobe used to ensure the early detection of fire and that the warning will be heard:

Heat Alarms

Rooms adjoining or on escape routes - kitchens, garages,

boiler houses etc. where Smoke Alarms are unsuitable. In stall within 5.3m (17 feet) of potential sources of fire.

Smoke Alarms

1. Within 7m (23 feet) of doors to rooms where a fire is likely to start. Corridors over 15m (46ft) should have more than

one Smoke Alarm.

2. On each storey.

3. Within 3m (10 feet) of bedroom doors - so warning will be heard.

4. All other rooms where a fire could start (except those with cooking/car fumes or condensation).

3. Positioning your Heat Alarm

Location must comply with applicable building regulations.

(a) Ceiling Mounting

Hot smoke rises and spreads out, so the Heat Alarm must be put on the ceiling- preferably in thecentre. The sensitive element (in the cylindrical protrusion) must not be less than 25mm (1 inch) or more than 150mm (6 inches) below the ceiling or roof.

The air is “dead” and does not move in corners, therefore Heat Alarms must be mounted away from corners. Place the unit at

least 30cm (12 inches) from any light fitting or decorative object which might obstruct the heat travelling to the Alarm. Keep at

IDEAL IN CENTRE OF CEILING

least 15 cm (6 inches) away from walls and corners. (See figure 2). Wall mounting is not recommended for Heat Alarms. If the ceiling has a pitched roof install an Alarm

within each apex.

(b) Locations to Avoid

Figure 2

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

Places where extremes of temperature may occur - below 4°C or above 43°C. e.g. attics, furnace rooms etc. Directly above ovens or kettles as the heat/steam could cause nui sance alarms.

Bathrooms, shower rooms or other rooms where the unit may be triggered by steam or condensation.

1. Pull Coveropen at Tab (2).Do not remove Coverfrom base.

2. Place the Base on ceiling or wall exactly where you want to mount the unit. With a pencil, mark the location of the Screw Holes (6)

3. Taking care to avoid any electrical wiring in the ceiling, drill a hole through thecenters of themarked locations. Push the plas tic Screw Anchors provided into the drilled holes. Screw in firmly.

(b) Connecting the battery.

With a pencil, write the date of Battery installation on the inside of the Cover to remind you when to replace the battery (4).

Lift Battery from Battery holder, and snap Battery Connectors to Battery. They fit together only one way (Figure 4).

NOTE: You may hear a loud chirp when attaching the Battery Connectors to the Battery. Test the installed Heat Alarm - see section 6(a) below.

Some models will be fitted with a battery missing indicator warning flag which pops up when the battery is removed. This pre vents the cover from closing when there is no battery in the unit. When the battery is being installed or changed, this flag must be held down while gently pushing the Battery into the Battery Holder. (see figure 5).

5. Interconnecting your Heat Alarms and Smoke Alarms.

A maximum of 12 interconnect EI 103, EI 100C and EI 105C Heat/Smoke Alarms may be wired together so that when one unit senses fire all other units sound a warning. This helps en sure the alarms will be heard.

Warning: Do not interconnect to any other Heat / Smoke Alarms

A maximum of 820 feet (250 metres) of wire can be used, (maxi mum resistance between detectors 50 ohm).The units areinter connected by wiring all the terminals marked 1 together, and all the terminals marked 2 together,as shown in Figure 6. An open ing should be made in the label covering the wiring hole in the base, and the wires routed into the unit as shown. Note that the

wiring inside the unit must be kept clear of the test button con tacts, and must not impede the air flow. Drafts from wiring open ings, conduit, or mounting boxes/holes, may blow smoke away from the sensing chamber, making it insensitive. It is essential that all such openings be closed by silicone sealant or similar.

TEST BUTTON

CONTACTS

After wiring together the Interconnect Alarms, test the first unit by pressing the button. All the detectors should alarm within 10 seconds and the red light only on the unit being tested, will flash about once a second. Check all the other units similarly.

These Alarms should be interconnected only within theconfines of a singlefamily living unit. Ifthey are connected 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.

6. Looking after your Heat Alarm

(a) Testing your Heat Alarm

It is recommended that you test your Heat Alarm once a week to be sure the unit is working. Press and hold the Test Button until the alarm sounds (it may take up to 10 seconds) see figure 7. It will also help you and your family to become familiar with the sound of the Alarm.

(b) Testing with Heat

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

WARNING: Do not test with flame.

This can be a fire hazard in itself.

If you want to check your Alarm with heat we recommend using

a hair dryer with a power rating of at least 1000 watts. Direct the

hot air as shown in figure 8 on to the heat sensor and the alarm

should sound within 30 seconds.

Figure 7

Figure 8

If the alarm fails to sound, follow this checklist.

1. Check BatteryConnectors to be sure they are firmly snapped to the Battery.

2. Replace the Battery. (Check the date marked on the Cover when you last replaced the Battery).

3. Refer to “Cleaning Your Heat Alarm” 6 (d).

A fresh battery should last about one year. When battery power is low andreplacement is necessary,the Alarm will “beep” about once per minute for at least 30 days. The battery must then be replaced. Replace battery if the alarm does not sound when the Test Button is pressed. For maximum reliability, replace battery at least once a year.

If the Power Indicator light ceases flashing every 40 seconds replace the battery. Be sure to replace the battery as soon as possible to ensure proper operation and to avoid a leaking battery. Leakage could cause damage to the Alarm, furniture, and car peting.

For replacement batteries, refer to the label inside the Heat Alarm Cover.

WARNING: Use of any other battery may be detrimental to the operation of the Heat Alarm.

(d) Cleaning your Heat Alarm

Heat Alarms arenot as susceptible todust and contamination as Smoke Alarms but it is prudent to clean them periodically. Use the narrow nozzle attachment of your vacuum cleaner to re move dust, insects and cobwebs from the sides and cover slots where the heat enters. To clean the cover, wipe with a damp cloth. Dry cover thoroughly with cloth.

WARNING: Do not paint your Heat 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.

7. Nuisance 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 smould-ering somewhere.

Check whether there is some source of heat, fumes or smoke, for example steam froma kettle triggering a Heat Alarm or cook ing fumes being drawn pasta Smoke Alarm by an extractor. The Heat Alarm or Smoke Alarm initiating the alarm can beidentified as it willhave a rapidlyflashing red light. If there are frequent nui sance/false alarms it may be necessary to re-locate the offend ing device away from the cause of the alarm.

8. (a) Important Safeguards

When using household protective devices, basic safety precau tions should always be followed, 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.

· For replacement batteries,refer to label insideHeat Alarm.

· NOTE: Constant exposure to high or freezing temperatures

or high humidity may reduce the life of the batteries.

· Do not disconnect battery to stop alarm sounding. (Fanning

vigorously with a newspaper or similar will remove heat from the Heat Alarm and stop it sounding.)

· Do not attempt to recharge or burn batteries, as they may

explode. Wrap in paper and discard normally.

· When removing battery, handle carefully to avoid possible

eye damage or skin irritation if battery has leaked or cor roded.

To maintain sensitivity to heat, do not paint or cover Heat Alarm in any manner; do not permit any accumulation of cobwebs, dust or grease.

If unit has been damaged in any way or does not function properly,do not attempt a repair. Return Heat Alarm (see Getting your Heat Alarm Serviced page 11.)

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

This is not a portable product. It must be mounted following the instructions in this leaflet.

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

(b) Limitations of Heat Alarms

Heat Alarms combined with Smoke Alarms can significantly help to reduce the risk of fire fatalities.

However independent authorities have stated that these sys tems may be ineffective in some fire situations. There are a number of reasons for this:
