Introduction
The EIB603CX Heat Alarm is a modified version of the standard EIB603C to
enable hardwired connection to a Brooks Residential Fire Alarm Panel (RFAP). The
combination of the Smoke and Heat Alarms with the RFAP provides for a residential
fire alarm system with features and capabilities beyond simple interconnected Smoke
/ Heat Alarms. To fully understand these added features, this leaflet should be read
in conjunction with the manual for the specific RFAP selected and the technical
datasheet for the interface mounting base.
The RFAP externally powers the heat alarm and provides the interconnect facility.
The Heat Alarms can be installed in kitchens and other areas where Smoke Alarms
are unsuitable.
EIB603CX and EIB650iWX are interconnected with hard wiring to the RFAP to give
the loudest alarm sound level throughout the house.
The EIB603CX can be used only with an RFAP, it cannot be used as standalone Heat
Alarm or connected to any other systems. As Brooks are continually developing new
products always check compatibility with the respective RFAP.
The Heat Alarm gives a fire warning when the nominal temperature at the Alarm
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 rooms adjoining escape routes, in conjunction with
Smoke Alarms on the escape routes.
6

Heat Alarms EIB603CX are supplementary to Smoke Alarms and must be
interconnected to the Smoke Alarms EIB650iWX to ensure that 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.
Locating your Smoke Alarm
The following two examples can be used as a guide line for locating your Smoke /
Heat Alarms to obtain the highest possible sound.
Multi-Storey Dwellings
If your home has more than one storey, at least one Alarm should be fitted on each
level (see Figure 1). The units will be hard-wired interconnected so as to give sufficient
warning throughout the property.
Figure 1 illustrates where Heat Alarms and Smoke Alarms should be located in a
typical two storey house. Note the spacings in “Protection Levels” as given in Figure 1
& 2 which ensure the early detection of fire and that the warning will be heard.
7

8
Locate Heat Alarms in rooms adjoining escape routes - kitchens, garages, boiler
houses etc. where Smoke Alarms are unsuitable. Install within 5.3m of potential
sources of fire.
Single Storey Dwelling
If the premises is one storey 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 that it can be heard loudly enough in the bedroom to wake
someone. See Figure 2 for placement example.
In houses with more than one sleeping area, Smoke Alarms should be placed
between each sleeping area and the living area and it is recommended that Heat
Alarms should be placed in the kitchen & garage.
Recommended Protection
Fire authorities recommend you put individual Smoke Alarms in or near all
rooms where fire is most likely to break out (apart from the locations to avoid e.g
bathrooms - see Section 3). The living room is the most likely place for a fire to
start at night, followed by the kitchen (where a Heat Alarm is recommended) and
then the dining room. Consideration should be given to installing 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.
In addition, consideration should be also given to installing Smoke Alarms in any
rooms where the occupant is unable to respond very well to a fire starting in that
room, such as an elderly or sick person or a very young child.

- every 7.5 metres of hallways and
rooms
- within 3 metres of all bedroom doors
- all units interconnected
For recommended protection
(in addition to the above):
- Smoke Alarms in every room (except
kitchens and bathrooms)
- Heat Alarms located in kitchens,
garages etc. within 5.3m of potential
fire sources 9
Figure 1

Checking Alarms Can Be Heard
With the Alarms sounding in their intended locations check that the alarm can be
heard in each bedroom with the door closed, above the sound of any TV/audio
systems. The TV/audio systems should be set to a reasonably loud conversation
level. If you cannot hear the alarm over the sound of the TV/audio system, the
chances are it would not wake you. Interconnecting the Alarms will help to ensure
that the alarm will be heard throughout the property.
Positioning
Ceiling Mounting
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 & Heat
Alarms must be mounted away from corners. Keep at least 0.3m from walls and
corners (see Figure 3). Additionally, mount the unit at least 0.3m from any light
fitting or decorative object which might prevent smoke or heat entering the Smoke/
Heat Alarm.
We do not recommend wall mounting these Smoke/Heat Alarms.
On a Sloping Ceiling
With a sloping or peaked ceiling install a Smoke or Heat Alarm between 500mm
min. and 1500mm max. of the peak (measured vertically). If this height is between
300mm min. and 500mm max. for Smoke Alarms or for Heat Alarms it is regarded
as being flat (see Figure 4).
10

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 away from sources of normal smoke/fumes. Use Heat Alarms
in kitchen, garages, etc.
• Locate away from very dusty or dirty areas as dust build-up in the chamber can
impair performance. It can also block the insect screen mesh and prevent smoke
from entering the smoke detector chamber.
• Do not locate in insect infested areas. Small insects getting into the smoke
detector chamber can cause intermittent alarms.

DON’T place Heat Alarms in any of the following areas:
• Bathrooms, shower rooms or other rooms 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 or be below -10°C (e.g.
attics, furnace rooms, directly above ovens or kettles etc.) 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 (e.g. attic
hatches). 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 (e.g. over stairwells) where it may be difficult to
reach the alarm (for testing, hushing or battery replacement).
• Locate the unit at least 1m from dimmer controlled lights and wiring as some
dimmers can cause interference.
• Locate unit at least 1.5m and route wiring at least 1m away from fluorescent light
fittings as electrical “noise” and/or flickering may affect the unit.

3. Installation
Installation Procedure
1. Select a location complying with the advice in Section 2.
2. The mounting plate (base) is supplied with an interface board to supply power
to the Alarm and communicate with other Alarms and the residential panel. (see
Figure 5).
3. Place the mounting plate on the ceiling exactly where you want to mount the
Alarm. With a pencil, mark the location of the two screw holes.
4. Run suitable 3 core cabling to the marked
locations of each Alarm. Make the connections
to the interface card (see Section 4).
5. Taking care to avoid any electrical wiring in
the ceiling, drill holes using a 5.0mm drill bit
through the centre of the marked locations.
Push the plastic screw anchors provided into
the drilled holes. Screw the mounting plate to
the ceiling.
6. Terminate the field wiring from the previous
alarm or the RFAP into the interface PCB
mounted inside the mounting base.
7. Carefully line up the unit on the base,
gentle press home & twist on.

Figure 5

8. Press the Test button on each Alarm to ensure that it
sounds (see Figure 6).
When all the alarms are connected to the panel and the
panel is powered, install all the other Alarms similarly.
Tamperproofing the Alarms
The Alarm can be made tamperproof to prevent unauthorised
removal of the Alarm.
Break off the small pillar on the base as shown in figure 7a.
To remove the Alarm from the ceiling it is now necessary to
use a small screwdriver, to release the catch (push catch towards the ceiling) and
then twist off the alarm (see figure 7b).
If necessary it is possible to further secure the Alarm by using a No.2 or No.4 (2 to
3mm diameter - not supplied) self tapping screw 6 to 8mm long (see figure 7d), to
firmly lock the Alarm and its mounting plate together (see figure 7c).
WARNING! To prevent injury and avoid malfunction, this apparatus must be
installed in accordance with the instructions provided.
Attach the Alarm to the mounting plate.

4. Interconnection - Hard Wired
The combined maximum of interconnected Smoke Alarms and/or Heat Alarms is
given in the specific system design manual. For example, 12 per zone in RFP6 and
15 in RFS1 can be interconnected together such that when one Alarm senses fire
all Alarms sound a warning. This helps ensure the alarm will be heard throughout
the property.
Do not connect to any other device as it may damage the unit or affect performance.
A maximum of 100 metres of three core cable, 1mm2, stranded signal cable
can be used, (maximum resistance between detectors 50 ohm). The Alarms are
interconnected by wiring all the terminals as shown in the system manuals.
Note: Draughts from wiring openings, conduit, or mounting boxes/holes, may blow
smoke away from the sensing chamber, making it insensitive. It is essential that all
such ceiling openings be closed with silicone sealant or similar.
1. Run 1 - 1.5mm2three core cable from the RFAP to the Alarm locations.
2. Bring the cable through the opening in the mounting plate (before screwing it to
the ceiling) (see figure 8).
3. If you are bringing the wiring along the surface, break out the two notches.
4. Screw the three cable cores into the terminal block on the interface card.
5. Twist the Alarm clockwise on to the mounting plate. Install and connect all the
other Alarms similarly.
Now test the first Alarm by pressing and holding the Test button (this may take
up to 5 seconds). The red indicator light will flash about once a second on the
first Alarm and all other Alarms should sound and the RFAP buzzer will sound.
(note: when the test button is released the local Smoke Alarm will stop sounding
16

but the interconnected Alarms and RFAP will
continue to sound for a further 3 seconds. This
allows one person to check the Alarms are
interconnected) Check all the other Alarms
similarly.
Note: These Alarms will be interconnected
within the confines of a single family living
unit. If they are connected between different
residences 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.
5. Testing, Maintenance & Power Supply Monitoring
Your Alarm is a life saving device and should be checked periodically. Regularly
check that the green light on the Alarm illuminates to show the units are powered.
Replace the Alarm if the green light is off.
5.1 Manually Testing your Alarms
It is recommended that you test your Alarms after installation and then at least
monthly to ensure the units are working. It will also help you and your family to
become familiar with the sound of the Alarms.
- Press and hold the Test Button until the Alarm sounds and the red light flashes
(see Figure 6), check that all interconnected Alarms and the RFAP sound.
17

- Release the Test button, the Alarm, RFAP and all connected Alarms should stop
sounding.
- Repeat this procedure within 30 seconds for all other Alarms in the system.
WARNING: Do not test with flame.
This can set fire to the Alarm and damage the house. We do not recommend testing
with smoke or heat as the results can be misleading unless special apparatus is used.
When you press the Test button it simulates the effect of smoke in a Smoke Alarm
and heat in a Heat Alarm which they could experience in a real fire. So, there is no
need to test either Alarms with smoke or heat.
5.2 Test/Hush Button to Control Nuisance Alarms
If, when the Alarm sounds, there is no sign of smoke or noise to indicate that there
is a fire, it should be assumed that it is due to an actual fire and the dwelling should
be evacuated immediately. Refer to the RFAP manuals for more details.
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 Alarm by an extractor.
If there are frequent nuisance/false alarms it may be necessary to re-locate the
Smoke Alarm away from the source of the fumes.
If kitchen usage/layout is such that there are an unacceptable level of nuisance
alarms, re-locate the Smoke Alarm further away where it will be less affected by
cooking fumes etc. We recommend the use of a Heat Alarm in the Kitchen area to
avoid such nuisance alarms.
18

5.3 Power Supply Monitoring
The power to the Heat / Smoke Alarms is monitored by the RFAP. If the wiring
between Alarms and the RFAP is short or open circuit, a fault indication will be
given at the RFAP. If EIB603CX is correctly connected to the interface board on the
mounting plate and power is being supplied by the RFAP, the steady illumination of
the green LED on each alarm indicates it is powered.
5.4 Cleaning your Alarm
Clean your Alarm regularly. Use a soft bristle brush or the brush attachment of your
vacuum cleaner to remove dust and cobwebs from the side slots where the smoke/
heat enters. To clean the cover, wipe with a damp cloth and dry thoroughly.
WARNING: Do not paint your Alarm.
Other than the maintenance and cleaning described in this leaflet, no other
customer servicing of this product is required. Repairs, when needed, must be
performed by the manufacturer.
5.5 Dust & Insect Contamination
All Smoke Alarms and particularly the photoelectric type are prone to dust and
insect ingress which can cause false alarms.
Heat Alarms are not as susceptible to dust and contamination as Smoke Alarms,
but it is prudent to clean them periodically.
The latest design, materials and manufacturing techniques have been used in the
construction of Brooks Alarms to minimise 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
Smoke Alarm should be promptly removed.
19

In certain circumstances even with regular cleaning, contamination can build up in
the smoke sensing chamber causing the alarm to sound. 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 all such servicing work.
5.6 End of life
The entire Alarm must be replaced if:-
• The unit is installed for over 10 years (check the “replace by” date marked on the
side of the unit).
• The Alarm fails to sound the horn loudly when the test button is pressed.
Do not put the Alarm into a fire.
The Alarm should be disposed in a safe and environmentally sound manner at your
local recycle centre. Contact your local authority for further advise.
6. Fire Safety Advice
When using household protective devices, basic safety precautions 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.
• Use the Alarm Test Button to familiarise your family with the Alarm sound and
to practice fire drills regularly with all family members. Alarm test button and fire
mode key switch are also provided in RFS1 and RFP6 respectively. Draw up a
