Fault relay functionality
1 = Alarm relay
2 = Fault relay
The relay module can be fitted into
the module interface on the Gira
smoke alarm device Dual detector
and is powered via the connecting
wires provided in the smoke
detector. Each module interface can
accommodate exactly one module,
meaning that radio modules cannot
be operated in smoke detectors at
the same time as relay modules.
Alarm relay functional test
The alarm relay is used to transmit
smoke/temperature alarms to the
connected device.
The alarm relay will trip as soon as
an alarm signal is generated by the
smoke detector.
The fault relay is used to transmit
the “Fault/detection head clogging”
and “Battery change due” warnings
to the connected device. The fault
relay will trip as soon as one of
these warnings is identified by the
smoke detector.
Operation with a wired network of
smoke detectors
When a wired network is used, only
faults with the smoke detector to
which relay is fitted will be
transmitted via the fault relay. In the
case that all smoke detectors need
to be monitored for faults, then each
one must be fitted with a relay
module.
Terminal designations
The potential-free terminals of the
fault relay are referred to as follows:

relay

24: Normally open contact for fault

The relay module extends the range
of functionality offered by the Gira
Smoke alarm device Dual/VdS. It
allows an external alarm device to
be connected, e.g. horn or warning
light.
In addition, it is possible for alarm
and fault messages to be routed
through, for example, a TeleCoppler
or central alarm system, or
transmitted via a push-button
interface to the EIB. The relay
module contains two relays, which
are energised under the following
conditions:
• the fault relay is energised if there
is a problem with the smoke
detector, e.g. “Battery change due”,
• the alarm relay is energised
if there is a local or networked
smoke/temperature alarm.
Operation with a wired network
of smoke detectors
When a wired network is used, the
alarm signal will be transmitted to all
connected smoke detectors via the
alarm relay.

Fitting the relay module
If the smoke detector is already
installed:
1) Remove the smoke detector from
the mounting plate or 230 V base.
Release the locking mechanism
(see “Installation and User Manual Smoke alarm Dual/VdS”) and turn
the smoke detector anticlockwise.
Remove the 9 V block battery.
Caution
The relay module must not be
fitted to the smoke detector with
the battery connected.
In every case:
3) Strip the ends of the connecting
wires for the relay module.
Ensure that the connecting wires
are long enough (approx. 10 cm)
to allow the relay module to be
inserted and removed easily.
When using a relay module with a
230 V base for dual smoke alarm
device/VdS, for safety reasons it
is important to ensure that the
insulation on the connecting wires
extends right up to the terminals
of the relay module.
4) Connect the connecting wires
to the relay module terminals
(J-Y(ST)Y 2x2x0.6 or YR 4x0.8).
Functional test
Always check that the smoke
detector to which the relay module is
connected is functioning correctly
when first installed and after every
battery change.
Alarm relay test
Trigger an alarm from the smoke
detector by pressing the button on
the smoke detector for at least 4
seconds. If the alarm relay is
functioning correctly it will switch to
the 12 contact.
Technical data
6) Connect the battery, position the
smoke detector in the mounting
plate or 230 V base and lock in
place by turning clockwise.
Fitting the battery
If the battery is not in place then
it will not be possible to lock the
detector into the mounting plate
or 230 V base.
7) Carry out a functional test on the
smoke detector.
Connecting an inductive
signalling device
If an inductive signalling device is
connected, then a suppressor
diode must be included in the
circuit.
