Smoke detector battery, titanium white

Smoke detector battery, tobacco
Product and functional description
The DELTA reflex smoke detector Battery (VdS approval
applied for) has been designed for use in the private
residential sector. In the event of a fire, the smoke detec-
tor detects the development of smoke in good time and
issues an alarm. In addition to stand-alone operation, up
to 40 smoke detectors of the same make can be net-
worked together via a twin-core cable.
It is also possible to fit the smoke detector with a plug-in
smoke detector module relay for external signalling de-
vices (e.g. horn, strobe light) or a plug-in smoke detector
module wave uni for radio transmission (GAMMA wave).
NOTE:
The exact functionality when using the relay module or
radio module can be taken from the corresponding oper-
ating and mounting instructions.
The DELTA reflex smoke detector battery is available in
the colours titanium white (similar to RAL 9010), alumin-
ium metallic (similar to RAL 9006) and tobacco (similar
to RAL 8019).
The function of the smoke detector is based on the pho-
toelectric scattered light principle without radioactive
preparations: an infrared transmitter and receiver (pho-
tocell) are arranged in the measuring chamber of the
smoke detector so that the emitted light signal of the
transmitter cannot directly hit the receiver. The smoke
originating from a fire penetrates the measuring chamber
and scatters the light signal emitted by the transmitter.
Due to the dispersion, the beams of light hit the light
receiver (photocell) and are converted into an electrical
signal which triggers the optical (flashing light signal) and
acoustic (pulsating signal tone, 85dB(A)) alarms.

The reset of the alarm is either carried out automatically
when the smoke has completely escaped the measuring
chamber or if the alarm/acknowledgement button has
been pressed.
The functional check of the smoke detector e.g. for
gradual pollution (dust deposits) is likewise carried out
by pressing the alarm/ acknowledgement button. If the
function is correct, a short acoustic signal is issued and
the LED flashes 10 times. Any possible faults are dis-
played visually by the continual flashing of a light signal.
The power supply of the smoke detector is ensured by
conventional batteries (3x1.5V miniature Alkaline, AA).
The typical battery service life of the smoke detector is
5 years without alarms. This also applies when the relay
module or radio module is connected. If the battery
voltage drops below a minimum level, the smoke detec-
tor reports that the batteries must be changed by send-
ing a cyclical optical and acoustic signal (short signal
tone) for at least 30 days. During this period, the smoke
detector is also fully functional even with the modules
connected.
To guarantee the function of the smoke detector, it is not
possible to install the detector without the batteries be-
ing inserted (battery compartment check). The reverse
voltage protection also prevents the smoke detector
from being damaged if the batteries are incorrectly in-
serted.
