Introduction
Deafgard is a Battery operated device designed to alert the deaf and hard of
hearing within rooms where the fire alarm is intended to do so.
Deafgard triggers into a fire alarm condition when it hears between 1 and 2.4
KHz of continuous sound over 75 Decibels in approximately 20 seconds. The
Pillow Pad is designed to be placed under a pillow and will vibrate to wake the
user. FIRE will be displayed on the LCD, the Strobe LEDs on the top of the unit
will flash and the Pillow Pad will vibrate. The Deafgard unit should be placed
next to the bed during use.

Important Information Prior to Use
Deafgard must only be used for the purpose for which it is
designed. It is not suitable for external use. Read this guide and
follow the instructions carefully. Keep this Guide in a safe place e.g.
in your Fire Risk Assessment File, for future reference.
Supplementary information about the sound of a fire alarm:
The British Standard for fire alarm installation, BS5839-1: 2002, (Clause 16.2),
states: “The sound pressure level of alarm signals should be generally, throughout all accessible areas of the building not less than 65dB(A) . . . where
the sound pressure level of background noise is greater than 60dB(A),
the sound pressure level of the fire alarm signal should be 5dB above the
sound pressure level of the background noise.”
It also states:The sound pressure level of alarm signals “should be not less than
75dB(A) at the bed head within rooms in which the fire alarm system is
intended to rouse people from sleep.”
Deafgard has been designed to the relevant parts of BS 5446-3: Specification
for smoke alarm kits for deaf and hard of hearing people.

LCD & Keypad
The LCD is back-lit and is used to
display the Time, Wake-up Alarm
settings, low Battery conditions and
any faults.
In a fire alarm condition, the LCD will
display “FIRE”.
The LCD will display any error
messages such as “PAD”.
Keypad
Common LCD readouts:
FIRE: Fire alarm has sounded
PAD: Pillow Pad cable has
detatched or has a fault.
SELF: Deafgard is conducting a
Self Test
TEST: Deafgard is conducting a
test after Button 4 has been
pressed.

The LEDs - Strobe and Status
The LED lens houses the 3 LEDs - one
Status LED in the centre and two Strobe
LEDs either side.
The Strobe LEDs will flash when in a fire
condition or if a major fault has occurred.
The Status LED will flash according to the
Deafgard status.
If Deafgard is turned On, under normal
conditions the Status LED will flash green
once every 15 seconds.
The Status LED will flash red once every 8
seconds if there is a minor fault, such as a
Pillow Pad error when the LCD will also
display “PAD”.
If a major fault occurs the Status LED will
flash red once every 4 seconds. This will
happen if Deafgard Batteries become
critically low. With this fault condition, at
15 second intervals, the Strobe LEDs will
flash and the Pillow Pad will vibrate for 4
seconds.
The Status LED will illuminate red
throughout a fire alarm condition.

Batteries - use 4 x C Size LR14
Use Alkaline Only (Do Not Use
Rechargeable Batteries)
The 4 x C Size Procell Alkaline Batteries
supplied should last at least 12 months.
Deafgard continually checks the Battery
life ensuring safe operation.
1. Open Battery Compartments using a
screwdriver.
2. Insert the Batteries into the Battery
Compartments (+) positive side facing
out. Inserting the Batteries the wrong
way could cause damage.
3. When closing the Battery
Compartments take care not to over
tighten.
When “BATT” is displayed on the LCD
there are 7 days of Battery life remaining,
it is recommended the Batteries are
replaced immediately.
Note. Deafgard saves all Wake-up
Alarm times after Batteries are
removed. But ‘real’ time will need to
be set.
Deafgard does not adjust
automatically for Daylight saving
time.
7
Setting the Time
The Time must be set when the Batteries
are removed or replaced.
To Set the Time:
1. Press Button 2 TIME SET and hold it
down until only the hour numeral is
shown on the LCD. Pressing this button
again allows you to set the minute.
2. Use Button 3 INCREMENT to adjust the
time. Holding down this button
increments the numeral in 1/2 second
stages.
Note. Deafgard operates a 24 hour
clock and does not adjust
automatically for Daylight saving
time.

Fire Alarm Test
1. Place Deafgard where it is to be used,
i.e. on the bedside table. Place the Pillow
Pad under the pillow.
2. Sound the fire alarm for a minimum of 30
seconds.
3. Deafgard activates within 20 seconds,
upon hearing the fire alarm.
4. Deafgard will remain in a fire alarm
condition until the fire alarm ceases.
5. Should Deafgard not respond to your fire
alarm, it may be that your alarm is too
quiet. See Sensitivity Adjustment or
contact the Technical Advice Line.
Note. When Deafgard activates
“FIRE” will be displayed on the LCD,
the Strobe LEDs on the top of the unit
will flash and the Pillow Pad will
vibrate.
The Deafgard unit should be placed
next to the bed during use with the
Pillow Pad under the pillow.
9
Using Deafgard
1. To turn the unit On press Button 1
ON/OFF.
2. The LCD will show 00:00 at first power
up or if the Batteries have been
removed, otherwise the time will be
displayed.
3. The Status LED will flash green every 15
seconds to show the unit is working
correctly.
4. To turn the unit Off hold Button 1
ON/OFF for 6 seconds, or until the LCD
turns Off. Deafgard will not work as
a wake-up device and the status LED
will no longer flash.
Once the unit is in location it is
recommended that unit be powered
On throughout the day.

Wake-up Alarm - Alarm Clock
Deafgard can be used as a wake-up Alarm
as well as a fire alarm for the deaf and hard
of hearing. When the Wake-up Alarm
activates the Pillow Pad will vibrate
constantly and the LCD will become
back-lit.
1. To set the Alarm Clock depress Button 5
ALARM SET and hold it until only the
hour numeral is shown on the LCD.
Pressing this button again allows you to
set the minute.
2. Use Button 3 INCREMENT to adjust the
time. Holding down this button
increments the numeral in 1/2 second
stages.
When activated, the
Wake-up Alarm can be
turned Off by pressing
Button 6 ALARM ON/OFF.
Once set, the bell symbol will be
displayed on the LCD to show the
Wake-up Alarm function is set and
On.
Button 4 MUTE/SNOOZE
will snooze the Wake-up
Alarm for 8 minutes on
first press, 4 minutes on
second and 2 minutes on
third.
To toggle the Alarm Clock On and Off
press Button 6 ALARM ON/OFF.
Note. The Strobe LEDs flash only
when the fire message is received.
11
Self Test
Deafgard performs a Self Test on Battery
insertion and every 7 days after that.
During the Self Test, Deafgard will check
its hardware and the LCD will read
“SELF”. Should Deafgard detect an
internal fault it will sound a warning tone,
vibrate its Pillow Pad, the Status LED will
flash red and the LCD will display the error.
To perform a quick test of the Deafgard
hardware hold Button 4 MUTE/SNOOZE
until the LCD displays “TEST”. The unit
will flash its Strobe LEDs, vibrate its Pillow
Pad.
Note. The Pillow Pad will not vibrate
if placed in the Cradle.
12
Sensitivity Adjustment
On identifying a necessary adjustment,
use a narrow electrical flat-headed
screwdriver. Take care not to over-adjust
as this will render the unit inoperative.
Sensitivity Adjustment if Deafgard is
not sensitive enough, i.e. does not
respond to the fire alarm:
Note. Deafgard is factory
set to be triggered into a
fire alarm condition at
75dB(A), as recommended
by BS 5839-1:2002.
Only adjust sensitivity as
a last resort.
1. Carefully insert screwdriver into hole on
back of the unit.
2. Turn clockwise through no more
than 5 degrees (a small adjustment is
equivalent to a large alteration in
sensitivity).
3. Test Deafgard to the fire alarm.
4. If problems persist, repeat steps 1-3.
Note. The Adjustment Screw is
limited in both directions, once you
can feel resistance against turning stop to avoid damaging the unit.
If Deafgard is too sensitive (responds to no
apparent sound) follow steps 1-4, but turn
anti-clockwise in Step 2.

Troubleshooting
The following are the most frequently
asked questions regarding the Deafgard
unit, with a quick checklist to follow:
1. Why does Deafgard not react to
your fire alarm?
• Check fire alarm is louder than 75dB.
• Check Batteries.
• Check fire alarm is sounding for at least
30 seconds.
• Adjust sensitivity of the Deafgard unit.
2. Why does the Pillow Pad not
vibrate?

• Check Batteries.
• Check cable from Pillow Pad is
connected securely to the Deafgard unit.
• Check Pillow Pad is not in the cradle.
Note. Deafgard will
display error messages on
the LCD if a fault occurs.
If this happens perform a
reset on the unit by
removing and re-insert
all Batteries. If error
remains contact the
Technical Advice Line.
3. Why do Strobe LEDs not flash?
• Check Power is On.
• Check Batteries.
• Check cable from Pillow Pad is
connected securely to the Deafgard unit.
