Operating instructions
These operating instructions for smoke detectors cover the following subjects:
• Function description
• Installation
• Operation
• Maintenance and care
• Technical data
They are aimed at the following target groups:
• Planners/architects/system integrators
• Fitters
• Specialists in smoke detectors
• Home owners
• Tenants
These operating instructions are an integral part of the product. After installation
|
and commissioning, they must be handed over to the user.
For your safety
½ CAUTION
• Smoke detectors detect smoke, but do not detect flames, heat or warmth
• Smoke detectors cannot extinguish fires!
• Reliable smoke detection only functions if a suitable installation location is cho-
sen and the smoke detectors are maintained at regular intervals.
• Do not paint over the smoke detector!
½
DANGER
Risk of fatal injury from smoke poisoning!
• Smoke fumes are highly poisonous. Just a few breaths result in loss of con-
sciousness and lead to death in a short time!
• In the event of a fire, get yourself and other persons to safety as quickly as pos-
sible.
• Assist children, the elderly and the disabled, in particular.
• Next, alert the fire services as quickly as possible!
• Spend time in advance thinking about how to behave in the event of a fire (es-
cape and evacuation measures) and about preventive fire protection.

Function description
The ARGUS Smoke Detector Single (hereafter called smoke detector) is a battery-oper-
ated smoke detector for private homes in accordance with EN14604 and vfdb14/01.
It promptly detects smoke from smouldering fires and open fires. An intensive acoustic
signal and a flashing LED warn persons of smoke fumes in good time, allowing them to
leave the danger area. The smoke detection works using the light scattering principle
(Tyndall effect). The detector measures the diffusion of beams of light in a smoke cham-
ber. If there is a large proportion of particles in the air due to smoke, the beams are reflect-
ed more strongly and reach a sensor that triggers an alarm.
The smoke detector is supplied with power from a permanently installed battery that has
a service life of at least 10 years in normal use.
The smoke detector continuously monitors the smoke detection function in the smoke
chamber and the battery's voltage. Malfunctions or a weak battery are indicated by acous-
tic signals and LED signals.
The smoke detector also offers various comfort functions.
Hush function
The hush function allows you to manually set smoke detection to be less sensitive for a
specific time. This is useful if you are expecting a lot of smoke or dust and want to avoid
an alarm.
Pressing the function key shortly sets the smoke detector to hush mode for about nine
minutes. This significantly scales up the alarm threshold and the alarm is not triggered.
The LED flashes every 10 seconds during this period.
The smoke detector automatically exits hush mode once the time expires. The normal
monitoring function is active again and the LED flashes as in its normal operating state
again.
Battery failure signal
The permanently installed battery of a smoke detector has a service life of at least 10
years in normal use. The frequency of alarms and the operating conditions have an impact
in the service life.
The battery failure signal begins in good time before the battery life ends (at least 30 days).
The smoke detector then emits a brief warning signal every 45 s. The LED flashes as in its
normal operating state (about every 6 min).
This gives you sufficient time to replace the smoke detector with a new one.
Self-test of smoke detection
The smoke detector carries out a self-test of smoke detection at regular intervals. To do
this, the smoke chamber and evaluation electronics are continuously tested. If an error oc-
curs during this testing, the smoke detector reports the malfunction with an acoustic sig-
nal. The LED flashes as in its normal operating state.
Pollution compensation
The smoke detector recognises that the smoke chamber ages continuously over the
years.
It adjusts the alarm threshold accordingly in order to avoid false alarms due to pollution
and ageing.
However, excessive pollution of the smoke chamber can trigger an alarm.
