Extinguishing system operation
Connection technique

For direct operating of an extinguishing system the module is necessary. This plug-in card is
manufactured to fit in the fire control panel. The allocation scheme of the connection clamps are to be
found within the terminal connection plan.


1.1 Inputs :

E2 ML automatic Operated by automatic fire detectors within cross zones with input
E3 (alarm output of a detector zone)

E3 ML automatic Operated by automatic fire detectors within cross zones with input
E2 (alarm output of a detector zone)

E4 ML automatic Operated by automatic fire detectors (alarm output of a detector

E5 ML PBD Operated by push-button detectors (alarm output of a detector

E7 Blocking Blocking equipment of the extinguishing system prevents
Operated by signal of the extinguishing system
E11 Door contact open door prevents triggering;
Operated by signal DC (door contact) of the fire panel

the inputs mentioned above are activated by switching an 0V-potential .

ML Emergency-Stop monitored line for connected emergency-stop button

ML Follow-up streaming monitored line for connected re-flooding button

The resistance allocation of the above mentioned lines can be found
in the wiring diagram.

2.2 Outputs :

A5 Relay pre-alarm potential-free changer,
Activation by one of the inputs E2-E5,
Deactivation by fire panel reset.

A7 Relay actuation potential-free changer,
Activation after expiration of the early warning time,
Deactivation by panel reset.

A10 Signal devices monitored operation line for connection of external signal devices,
protected with 400 mA.
Activation with the beginning of the early warning time.
The signal devices are normally deactivated with the button panel
reset. If the parameter 23 of the panel is set to 1, a deactivation is
also possible with the button ext. signal transmitters on/off, but only
when a triggering of the extinguishing system has been carried out,
i.e. not during the early warning time.

A11 MV1 monitored operation line for switching functions, protected with 1A.
Activation with the beginning of the early warning time.
Deactivation by panel reset.

A12 MV2 monitored triggering line for operation of the fire extinguishing
Protected with 1A.
Activation with the beginning of the flood time
Deactivation by panel reset or after expiry of the flood time.

A13 Relay emergency-stop potential-free changer,
Activation as long as the emergency-stop button is being pushed

A14 Relay re-flooding potential-free changer,
Activation by the button re-flooding after expiry of the flooding time.
Activation as long as the button is being pushed, but with a
maximum of the flood time which is set.

A15 Re-flooding monitored control line for triggering the fire extinguishing system,
protected with 1A.
Activation by the button re-flooding after expiry of the flooding time.
Activation as long as the button is being pushed, but with a
maximum of the flood time which is set.


On the extinguish control card, you can find 3 DIP-switches (see service plan at the end of the chapter).
The labelling and function of this 8-pole DIP-switch is as follows :
- Flooding : Adjusting of the flood time within binary code. 1 digit = 5 seconds, this makes
an adjusting range of 0-1270 seconds. An unlimited flooding time is set if all 8
switches are „off“.
- Pre-warning : Adjusting of the flooding time within binary code. 1 Digit = 5 seconds. Maximum
time = 60 seconds. A higher time value is automatically set back to 60 seconds.
- IIC : Adjusting of the card address within binary code. Valid card addresses are
between 1-8.

The pre-warning and flooding times should be made visible by labelling the DIP-switches.

Display, operation and programming

The pre-set card address is responsible for the detector zone that is occupied by the extinguish control

Address 1: Detector zone 1-8
Address 2: Detector zone 9-16

With the programming software DBMTOOL, this zone assignment can be changed randomly.
The assignment of the primary lines to the 8 detector zones of the extinguishing control card is as follows:
Detector zone 1: A10 signal devices
Detector zone 2: A11 magnetic valve 1
Detector zone 3: A12 magnetic valve 2
Detector zone 4: A15 re-flood
Detector zone 5: detector zone emergency-stop
Detector zone 6: detector zone re-flood
Detector zone 7: unused
Detector zone 8: unused

The switching on/off of the detector zones works like described in 13.2. An unusual feature, though, is the
fact that if the signal devices are switched off, the magnetic valves MV1 (A11) and MV2 (A12)
automatically are turned off, too. This avoids a triggering without a previous alarm. If the magnetic valve
MV (A12) is turned on, the signal devices (A10) are also automatically switched on. The detector zones‘
emergency stop and re-flooding for connection of the relevant buttons are to be programmed in the alarm
organization as a fault detector zone with input 4.

Decline monitoring

The monitoring of extinguishing loss can be realised with an input module. This module is connected to
the detector line in an addressable system. The input module has a monitored input line which has to be
locked with a resistance of 20 K/ohm. By means of a parallel circuit of 1 K/ohm resistance, the decline
report is being triggered. One or more input modules have to be programmed into a detector zone of their
own. This detector zone then is programmed as a fault reporting group with input 5 according to the
alarm organization.


The fire panel offers a variety of possibilities to handle internal and external controls.

Electronic outputs

- Collective outputs (connection plans page 8+)
- 8 alarm outputs on each detector zone (connection plans pages
3+/4+/12+). With the use of a multiple area extinguishing system, the
alarm outputs of the detector assembly which triggers the extinguishing
control card is assigned to fixed detector addresses.
- This guarantees an independent triggering of the extinguish system by the
detector assembly, even if the control panel has a failure.
- For this function, a special software is used with in the corresponding
detector assemblies and which receives, in addition to the software-
version, the supplement „L“. The assignment of the alarm outputs to the
detector addresses is as follows:

Segment 1: Address 1-31 Output 1
Address 32-63 Output 2
Address 64-95 Output 3
Address 96-126 Output 4
Segment 2: Address 1-31 Output 5
Address 32-63 Output 6
Address 64-95 Output 7
Address 96-126 Output 8

- 32 alarm outputs on the alarm module (see terminal connection plans)


- Collective relay UE-Alarm, Alarm und fault (see terminal connection
- Relay pcb DBM014 (see terminal connection plans) . The relay pcb
contains 8 potential-free changers. Every single
relay has a control input of its‘ own which can be
actuated by operated electronic outputs.

External output modules

- Modules with a potential-free changer (output module) or a monitored
control line (sounder control module), which can be connected to an
addressable system on the detector line. The operation of these modules
are freely programmable.
