Interconnecting smoke detectors
You can interconnect up to 10 Gira smoke detector.
The detectors are connected in parallel with a two-conductor cable
(e.g. phone cable: J-Y(St)Y 2 x 2 x 0.6 mm). The total cable length of the
detector network may not exceed 450 m.
Proceed as follows in order to interconnect the smoke detector:
1. Pull the terminal block from the smoke detector PCB.
2. Connect the terminals with colour marking (green = plus; grey =
minus) to the cable as shown in the figure.
To do so, insert the bared conductors into the opened snap-in termi-
nals and close the terminals by pressing the levers downwards.
3. Insert the terminal block back onto the PCB.
Inserting a module
The optionally available modules can be used to extend the functional
scope of the smoke detector modularly. Detailed information on the type
and function of the modules can be found in the instructions of the
respective modules.
In order to install a module please proceed as follows:
1. Remove the tab (greyed in the figure) by
levering it out with a suitable tool
(for example a screwdriver).
2. Insert the module into the slot.
Operating and alarm signals
Battery check - Changing the battery
The smoke detector is supplied with voltage by a 9 V monobloc battery.
The battery test automatically checks the supply voltage in regular inter-
vals. If the battery voltage drops below a defined point, the smoke detec-
tor signals for 30 days that the battery has to be replaced. The smoke
detector is completely functional during this period.
Proceed as follows to replace the battery:
1. Remove the smoke detector from the base (turn counter-clockwise).
2. Remove the old battery from the compartment and disconnect the
connector from the battery connection.
3. Connect the new 9 V monobloc battery to the battery connection and
insert the battery into the battery compartment.
4. Insert the smoke detector back into the base and latch it in by turning
it slightly clockwise.
5. Carry out a function test.
Maintenance and care
In order to ensure the functional reliability of the smoke detector for a
longer period, you should carry out maintenance once a month (or when
a fault message occurs):
1. Remove the smoke detector from the base (turn counter-clockwise)
and remove the dust.
2. Wipe the smoke detector with a moist cloth.
3. Insert the smoke detector back into the base and turn it clockwise
until it latches in.
4. Check whether the automatic self-test is carried out (smoke detector
flashes every 45 seconds.
5. Carry out a function test.
Function test
Carry out the function test once a month:
1. Press the test button (Page 11):
If the signal sound is emitted, the smoke detector operated correctly.
If no signal sound is emitted, replace the battery.
2. Then, carry out the function test again.
If a signal sound is still not emitted, the smoke detector is defective
and has to be replaced.
If an function test is carried out at interconnected smoke detectors, all
the connected smoke detectors emit an acoustic alarm. If they do not,
check the batteries of all the smoke detectors as well as the connections
and the state of all the interconnecting cables.
Operating test for radio-networked smoke detectors
To conduct the operating test on radio-networked smoke detectors,
please proceed as follows:
1. Remove the smoke detector from which you want to transmit the test
telegram from the base.
2. Activate the test function on the radio module of this smoke detector
by briefly pressing the programming button.
The active test function is indicated by the programming LED flash-
ing.
When the test function is active, the signal transmitter of this smoke
detector is muted.
3. Press and hold the test button on the smoke detector (for a maximum
of 45 seconds) until all assigned smoke detectors output an acoustic
alarm.
If one or several smoke detectors does/do not output an acoustic alarm,
please check the batteries of all smoke detectors and the radio assign-
ments.
Functional principle
The smoke detector recognises fire early on due to the smoke develop-
ment. It operates on the scattered-light principle. Light transmitters and
receivers are positioned in the measuring chamber so that the emitted
light signal of the transmitter cannot impact the receiver directly. If
smoke enters the smoke chamber, the light signal is scattered by the
floating particles contained in the smoke. The scattered light rays impact
the photo cell where they are converted into electrical signals which trig-
ger the alarm. The function of the smoke evaluation is checked con-
stantly. Any faults are indicated by a fault signal (signal sound and LED).

Caution!
The operation of the smoke alarm may be affected by air currents. Make
sure that the cable entry is locked in the cover range with a suitable
sealing compound (silicone).

Interconnection termin
als remain active
The interconnection terminals of the smoke
detector also remain active when the module
is inserted and can continue to be used.

Caution: Hearing damage possible
The smoke detector generates a very loud and shrill sound which can
damage your hearing. Therefore stay at least 50 cm away from it during
an function test.
i
Press and hold test button for 45 seconds
For smoke detectors which are interconnected via radio modules, it can
take up to 45 seconds until the radio module receives the alarm tele-
gram. For this reason, the test button of the triggering smoke detector
must be pressed for up to 45 seconds when conducting an operating
test with radio-networked smoke detectors.
