Introduction
Deafgard is a battery operated device designed to rouse the deaf and hard of
hearing within rooms where the fire alarm is intended to do so.
IMPORTANT:
Read this guide and follow the instructions carefully and keep it in a safe place
e.g. Your Fire Risk Assessment File, for future reference.
Information about the sound of a fire alarm:
The British Standard for fire alarm installation, BS5839-1: 2002, (Clause 16.2).
‘’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’’.

Batteries- Use Alkaline Only
(Do Not Use Rechargeable Batteries)
The 4 x C Size Procell Alkaline cells supplied should last for at least 12 months.
Deafgard continually checks the battery life ensuring safe operation.
Insert the 2 cells into each of the 2 battery compartments, negative end first.
Inserting the cells the wrong way could cause damage to the unit. When closing the
battery compartments use a Phillips / Pozidrive No.2 screwdriver, taking care not to
over tighten.
When the batteries require changing the battery icon on the LCD will flash.
Battery life may be reduced in noisy environments.

Turning the unit on for the first time or after changing batteries
Depress the on/off button (top left button on the keypad marked 1 on diagram page
3) to turn the listening circuitry on. The listening circuits will remain active until
the unit is manually switched off.
The LCD will also flash to inform the user that the time needs to be set. (read 2 Time
Set below) The LCD will flash for 30 seconds.
Turning the unit on when in passive mode (batteries installed and time
set)
Depress the on/off button (top left button on the keypad) to turn the listening
circuitry on. The listening circuits will remain active until the unit is manually
switched off.
The LCD will display the time.
Turning the unit off
Depress the on/off button (top left button on the keypad) for more than 3 seconds to
turn the LCD and listening circuits off. If the time has been set, the internal timer
will continue to run despite the unit being turned off.
2) Time Set
You must set the time after turning the unit on, and the LCD is still
flashing.
The time set button is the middle button in the top row of the control panel. To
initiate the time set sequence it must be depressed for more than a second.
The LCD hour numerals should now flash. To change the hour numerals, tap the
LCD adjust button (the far right button in the top row of the control panel). Each
time you tap this button the time will increase by 1 hour – if you continuously hold
this button down the hour shown will increase until you release the button. When
you have set the clock to the desired hour, depress the time set button again until
the minute numerals on the LCD flash. To change the minute numerals, tap the
LCD adjust button (the far right button in the top row of the control panel). Each
time you tap this button the time will increase by 1 minute – if you continuously
hold this button down the minute shown will increase until you release the button.
Once the hours and minutes have been set to the desired time, depress the time set
button until the LCD display is continuous.
The unit is now primed to listen for fire alarms.

3) Alarm Set
The unit must be turned on and have the time set before you can set the alarm
function. Depress the alarm set button (button 5 in the bottom row) in order to
activate the alarm set function. Once the alarm time on the LCD is flashing, simply
use the alarm set button in conjunction with the LCD adjust button (button 3 in the
top row of the control panel) in the same way as when setting the time – see section
2 above.
4) Alarm On/Off
The alarm must be set before it can be turned on or off – see section 3 above.
To turn the alarm on/off simply tap the alarm on/off button (button 6 in the bottom
row), this will toggle between the alarm on and alarm off function. When the alarm
is on, the LCD will display the bell icon and when the alarm is off, no icon will be
shown.
Turning the alarm off while it is sounding
To turn the alarm off once it has woken you, simply depress the alarm on/off button
until the alarm ceases to sound/vibrate.
5) Mute/Snooze and Test
5a Mute
If the unit detects a fire alarm condition, the pillow pad will vibrate, the strobe will
flash and the LCD will flash displaying a FIRE message. The unit can be muted for
thirty seconds by depressing the mute/snooze button (button 4 in the bottom row of
the control panel) until it stops. This state will only last for 30 seconds before the
Deafgard alerts the user again.
5b Snooze
If the Deafgard is being used as an alarm clock, the pillow pad will vibrate and the
LCD will illuminate to show the time. Tapping the mute/snooze button the unit will
snooze for 8 minutes, if the snooze button is tapped again after this 8 minutes the
unit will enter snooze mode but this time for 4 minutes. Tap the snooze button after
these 4 minutes and the unit will snooze for a further 2 minutes, after these two
minutes have elapsed the unit will no longer let you snooze.
5c Test
As long as the unit is turned on, it can be tested. Remove the pillow pad from the
cradle keep the mute/snooze button depressed until the strobe flashes and the
pillow pad vibrates. The test will only last for 5 seconds.
Note: the pillow pad will not vibrate when in the cradle.

Testing Deafgard to the Fire Alarm
1) Turn unit on – see operating section
2) Sound the fire alarm for a minimum of 30 seconds.
3) Deafgard will notify you of the alarm within 20 seconds.
4) Should Deafgard not respond to your fire alarm, it may be that your alarm is too
quiet. Contact Technical Assistance.
Note: Alterations to the premises i.e. new furniture, new carpets etc, may alter the
audibility of the fire alarm. Following alterations a fire alarm test must be carried out
to ensure that Deafgard responds. If it fails to respond to the alarm contact
Technical Assistance. Despite Deafgard self-testing every 7 days, weekly bell tests
are highly recommended. This will ensure that Deafgard is responding to the fire
alarm.
