Operating instructions
7.6 Connecting the signal technology
Depending on the equipment of the device, you have up to three different
methods with which to connect signal technology to the gas warning de-
vice and to control and supply it with current.
This section describes the bugle relay, the relay output circuit board and
the optocoupler output circuit board.
Precondition for action:
ü
The housing is open.
ü
The voltage supply has been disconnected and protected against
re-connection.
Resources required:
@ Signal technology
7.6.1 Horn relay
You can connect an individual signal bugle to the bugle relay
(clamps 41 - 43) and control it. If a signal bugle is connected to the bugle
relay, the alarm message must be confirmed directly on the device. The
bugle relay is especially suited for an alarm at the first limit value.
41 42 43
Fig. 9: Horn relay
Terminal Function Description
41 + 42 normal off
The relay works on these
clamps as a closer.
42 + 43 normal on
The relay works on these
clamps as an opener.
Table 11: Bugle relay clamp connection
Perform the following steps:
1.
Fit the signal bugle.
2.
Lead the connecting cable through a cable screw connection to the
underside of the device.
3.
Connect the signal technology used either to clamps 41 and 42 (nor-
mal off) or 42 and 43 (normal on).

Note: You can adjust the action of the bugle relay in the output set-
tings. Further information is available in section 8.2.2.1 “Bugle” on
page 19.
ü
Connection of the signal bugle complete.
7.6.2 Output circuit board (relay)
You can control the signal technology (e.g. bugles or signal lamps) with
the relay output circuit boards. To this end, the device can be fitted with
up to four relay output circuit boards, which can be used for a pre-alarm
and a master alarm respectively.
Application example: You can evaluate sensors in two different rooms us-
ing two relay output circuit boards.
Section 8.1 “First steps” on page 18 informs you how to set the limit
values individually.

Perform the following steps:
1.
Fit the signal technology.
2.
Lead the connecting cable through one of the cable screw connec-
tions to the underside of the device.
3.
Connect the signal device for the master alarm to the clamps 1 + 2.
4.
Connect the signal device for the pre-alarm to the clamps 3 + 4.

i Only the limit values 1 and 2 can be outputted from out-
puts 1 and 2.
Only outputs 3 and 4 are freely-configurable and can output
further signals.
