220~240V AC OPERATED HEAT ALARM WITH RADIO LINK

PRODUCT DESCRIPTION
220~240V AC OPERATED
HEAT ALARM WITH
RADIO LINK (868MHz)
(FIXED TEMPERATURE TYPE)
Heat Alarms are intended to be supplementary to Smoke Alarms and
should only be placed in areas where smoke alarms cannot be used.
HSSA/HE/RF is a multiple station heat alarm with a radio link mounting
base which allows it to be interconnected to other Hispec alarms. (Can be
mixed and matched with the Hispec Photoelectric Smoke Alarm
HSSA/PE/RF and the Heat Alarm HSSA/HE/RF). The radio link base has
both signal transmitter and receiver built-in. It transmits a Radio
Frequency (RF) alarm signal when the unit gets heat. When it receives an
RF alarm signal from other unit, it will sound. This interconnect feature
allows up to 20 units to be interconnected together within 80 meters and
thus all alarms will sound when any one is activated. Using the wireless
signal transmission technology avoids wiring location problem and allows
the smoke and heat alarms to be placed further apart when compared to
a wired installation.
If your dwelling is multi-storey, for minimum protection one
alarm should be fitted at the bottom of the staircase with further
alarms fitted on each upstairs landing. This includes
basements but excludes crawl spaces and unfinished attics.
See Figure 2 for examples.
NOTE: For maximum protection Smoke Alarms should be fitted
in every room (except kitchen, bathroom and garage). Heat
Alarms located in kitchens, garages, boiler rooms etc. within
5.3m (17ft) of potential fire sources.
DO NOT FIT THE HEAT ALARM IN THE BATHROOM,
SHOWER ROOMS or other room where the unit may be
triggered by steam or condensation.
POSITIONING THE HEAT ALARM
Note: This heat alarm cannot be connected to any other device such
as a fire alarm panel.

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 heat.
This Heat alarm gives a fire warning when the temperature at the unit
reaches 60ºC. It is ideal for kitchens, garages, cellars, boiler rooms,
attics and other areas where there are normally high levels of fumes,
smoke or dust which preclude the use of Heat Alarms due to the risk of
false alarms.
LOCATING THE HEAT ALARM
If your dwelling is on a single storey, for minimum protection you should
fit an alarm in a corridor or hallway between the sleeping and living
areas (incl. Kitchens). Place it as near to the living areas as possible and
ensure the audible alarm can be heard when the bedrooms are
occupied. See Figure 1 for examples.
Ceiling Mounting
As hot smoke rises and spread out, it is advisable to mount on
a ceiling in a central position. Avoid areas where there is no air
circulation, e.g. corners of rooms and keep away from items
which may prevent the free flow of air. Place the unit at least
300mm from and light fitting or decorative object which might
obstruct heat / smoke entering the alarm. Keep at least 300mm
away from walls. See Figure 3i.
Wall Mounting
Do not mount tight into the corners. Put the top edge of your
smoke alarm between 150 and 300mm below the ceiling. Keep
at least 300mm from room corners. See Figure 3i
(Wall mounting is not recommended for Heat Alarms)
On a Sloping Ceiling
In areas with sloping or peaked ceilings install your Heat Alarm
900mm from the highest point measured horizontally because
“dead air” at the apex may prevent heat from reaching the unit.
See Figure 3ii.

Do not locate in insect infested areas. Insects and
contamination on the alarm sensor can increase its response
time.
INSTALLING THE HEAT ALARM
WARNING – This heat alarm is mains powered and requires
wiring by a qualified electrician in accordance with the current
IEE Regulations for Electrical Installations (BS7671).
The circuit used to power the heat alarm must be a dedicated
permanent supply that cannot be switched off accidentally by the
normal user. Before installing ensure the electrical supply is
isolated.
WARNING – To prevent injury, this heat alarm must be securely
attached to the ceiling/wall in accordance with the installation
instructions.
All hardwired interconnect heat alarms must be supplied from a single
power circuit and a common neutral must be used.
WARNING – Do not connect the interconnect wire to Live or
Neutral.



Disconnect the AC main power from the circuit that is going to
be used.
Having established the mounting location install a junction box
suitable for locating the termination point. Ensure that there is
no other electrical wiring or pipe work in the area adjacent to the
mounting surface.
Unlock the detector unit from the base by pushing up the
temporary latch with a screw driver. See Figure 4

MAXIMUM PROTECTION
MINIMUM PROTECTION
Areas to be avoided include the following : Situations where the temperature may fall below 4oC or
rise above 40oC
 Humid areas such as bathrooms, shower rooms where
the relative humidity may exceed 90%
 Near a decorative object, door, light fitting, window
moulding etc., that may prevent heat from entering the
alarm.
 Adjacent to or directly above hot components such as
radiators or wall vents that can effect the direction of air
currents.
 In very dusty or dirty environments such as workshops.
 Locate unit at least 1.5m and route wiring at least 1m
away for fluorescent light fittings as electrical “noise”
and/or flickering may affect the unit. Do not wire into the
same circuit as fluorescent lights or dimmers.

Set the coding. Each unit carries a four positions dip switch (see
Figure 6) for coding the transmit and receive frequency to prevent
interference with any other RF equipment. There are 16
combinations.
Figure 6 – DIP Switch Facility


IMPORTANT!
The setting of the dip switch must be the same on all
interconnected units.

Connect the wires to the correct terminals on the
mounting base and fix the mounting base in position.
Ensure the screws are fully tightened. See Figure 5.


Assemble alarm onto the mounting plate by sliding it in according
to the direction of the arrows.
Restore the AC supply
Test the correct operation of the heat alarm by depressing the test
button on the front of the detector. The unit should emit a loud
pulsating alarm.
Should use 2.1mm wire for connection.
OPERATING YOUR HEAT ALARM
Once the heat alarm has been installed a small GREEN indicator light
(LED) should be visible through the alarm grill indicating that AC supply
is healthy. A RED indicator light (LED) should also flash approximately
once a minute to indicate the battery is healthy and the unit is operating
properly.
If heat is checked over a range, the unit will emit a load pulsating alarm
and a RED indicator light (LED) will be flashing quickly at the same time
until the air is clear.
The alarm must be wired in accordance with National
wiring codes.
LIVE: connect to house wires coloured brown, red or marked
with L.
NEUTRAL: connect to house wires coloured blue, black or
marked with N.
INTERCONNECT: normally not used except to hardwire
interconnect to mains heat alarm (Hispec model HSSA/HE) or
smoke (Hispec model HSSA/PE). Never use EARTH wire for
interconnect wire.
At normal time, the radio link module is working under sleep mode. It will
open the receiving window at a short time around every 20 seconds. In
order to awake it and set it at transmission mode, the simplest way is to
press the test button on top of the heat detector. It will continually transmit
as long as the button is pressed.
To test two units’ transmission and reception performances/ parameters,
it is important to set them with the same code. The dip switch for setting
the code is available on the mounting base of the unit. When one is at its
receiving mode, it can receive a triggering signal from the transmitting unit
within 20 seconds. As soon as the receiving unit gets the signal, it will
activate the alarm to sound loudly until the transmitting signal is vanished.
TESTING YOUR HEAT ALARM
It is recommended that you test your heat alarm once a week to ensure
the detector is working correctly.
Push and hold the test button for approximately 3 seconds. A loud
pulsating alarm should sound and a RED indicator light (LED) will flash
at the same time.
NOTE – for multiple interconnected heat alarms (either by radio link or
hardwire), only the RED indicator light (LED) of the originating unit will
flash rapidly. All other units in the interconnect system will sound an
alarm (for radio link interconnected units, it will sound within 20 seconds)
but their RED indicator light (LED) will NOT flash. Test each alarm
checking that the alarm is triggered on all other alarms installed.
HUSH OR SILENCE FEATURE
WARNING: Connection to the EARTH terminal is not
needed for correct functioning of the Heat Alarm. It is just
for conveniently terminating any earth supply wire
coloured green or green/yellow. It does not provide
protective earthing for the Heat Alarm.


Insert a 9V battery firmly into battery compartment on
the rear of the alarm. NOTE POLARITY OF
CONNECTIONS. Ensure the metal tab is fully depressed
when the battery has been fitted.
NOTE – For the safety of the end user the heat alarm
cannot be fitted without its battery.
Before assembly to base plate test the correct operation
of the heat alarm (operating from the battery only) by
depressing the test button on the front of the alarm. The
unit should emit a loud pulsating alarm.)
This Heat Alarm has a built-in Hush or Silence feature incorporated into
the Test button. If cooking or other non-hazardous sources cause the
unwanted alarm, it can be temporarily silenced by depressing the test
button and holding for approximately 3 seconds. The alarm will enter a
dormant period for 10 minutes. The red LED will flash every 10 seconds
to indicate the sensitivity is reduced. At the end of the hush period the
alarm will reset to normal sensitivity.
NOTE – If the heat density increases during this period (i.e. from a fire)
the unit will go into alarm mode.
LOW BATTERY WARNING
If the heat alarm emits a short ‘beep’ once a minute the battery is at the
end of its life and should be replaced immediately. This low voltage
warning will be given for at least 30 days. In this case, the other
interconnected units in the system which are not in low battery condition
will chirps for a few seconds once a hour as long as the detector with the
“dead” battery beeps. If the red indicator light (LED) does not
flash every minute then replace the battery.
BATTERY REPLACEMENT
Always TURN OFF the A.C. supply to the heat alarm before
replacing the battery. Replace the battery at least once
annually, or immediately when the low battery signal sounds
once a minute, even though the heat alarm is receiving A.C.
power.
Test the alarm for correct operation using the test facility
whenever the battery is replaced.
WARNING: DANGER OF EXPLOSION IF BATTERY IS
INCORRECTLY REPLACED. THE USE OF BATTERIES OTHER
THAN THOSE RECOMMENDED ON THE BACK OF THE HEAT
ALARM MAY BE DETRIMENTAL TO ITS OPERATION
The battery should only be replaced by a qualified electrician or
similarly qualified person.
 Turn off the A.C. power supply to the heat alarm.
 Gently slide the heat alarm out from the mounting plate.
 Remove the battery from the compartment.
 Insert a new, healthy 9V battery. NOTE POLARITY OF
CONNECTIONS. Ensure the metal tab is fully
depressed when the battery has been fitted
 Using the Push-to-Test button, test the heat alarm to
verify 9V DC battery back-up. See “TESTING YOUR
HEAT ALARM”
 Reattached the heat alarm to the mounting plate by
sliding until it snaps into place.
 Turn on the AC power and test the heat alarm using the
Push-to-Test button. See “TESTING YOUR HEAT
ALARM”
MAINTAINING YOUR HEAT ALARM
Clean your heat alarm at least once every six months to
prevent dust build up. This can be done using a vacuum
cleaner with the brush attachment. Clean gently around the
front grilled section and sides.
The apparatus shall not be exposed to dripping or
splashing and no objects filled with liquids, such as vases,
shall be placed on the apparatus.
IMPORTANT SAFEGUARDS
Installation of your heat alarm is only one step in your safety
plan. Other important steps should be taken to further improve
your safety: Install the heat alarm properly, following this instruction
leaflet
 Test your heat alarm weekly
 Replace the battery immediately once depleted
 Do not heat in bed
 Keep matches & lighters away from children
 Store flammable materials in a proper manner and never
use them near naked flames or sparks
 Maintain emergency equipment such as Fire
Extinguishers, escape ladders etc and ensure all
occupants know how to use them correctly.
 Plan an escape route/s from your building in advance
and ensure all occupants are aware of them. Re-enforce
this awareness periodically through-out the year.

Make sure escape routes remain free of any obstructions.
WARNING: IF THERE IS ANY QUESTION AS TO THE CAUSE OF AN
ALARM IT SHOULD BE ASSUMED THAT THE ALARM IS DUE TO AN
ACTUAL FIRE AND THE DWELLING SHOULD BE EVACUATED
IMMEDIATELY.
LIMITATIONS OF THE HEAT ALARM



Heat Alarms are not designed to protect life safety against fire
and smoke. In most fires, hazardous levels of toxics gases and
smoke can build up before the Heat Alarm will operate. In cases
where life safety is an issue, Heat Alarms should only be used
to provide an added source of protection.
Heat alarms cannot provide an alarm if heat does not reach the
alarm. Therefore, Heat Alarms may not sense fires starting in
chimneys, walls, on roofs, on the other side of a closed door or
on a different floor. It should be installed in each sleeping area,
on every level of a home and be interconnected with each other
and the heat alarms.
Home fires develop in different ways and are often
unpredictable. No one type of alarm is always best, and a given
alarm may not always provide warning of a fire.
