ESCRIPTION
The KAL426C allows the connection and control of 1 extinguishing
area to an analogue fire system.
The module incorporates 3 pre-programmed monitored inputs,
3 pre-programmed monitored outputs and a status LED.
The available inputs are:
Stop extinguishing - manual call point (PP)
Start extinguishing - manual call point (PD)
Gas bottle pressure monitoring - presostate (PR)
The available outputs are:
Activate extinguishing solenoid (SB)
Activate extinguishing pre-alarm warning siren (SP)
Activate extinguishing alarm warning light (SL)
The status LED is lit constantly during alarm.

NSTALLATION
For general guidelines on fire system planning,
design,
installation,
maintenance refer to the EN54-14 (2001) standard
and local regulations.
The module is designed for cabinet installation and must be
protected against environmental agents. The 24 VDC power
supply is taken from an auxiliary power source. The power supply
should be disconnected during installation.
An end-of-line resistor (4K7Ω) must be installed at the end of all
input / output lines
except for the pressure switch (PR) and
solenoid (SB) lines (for the pressure switch no EOL resistor is
required, for the solenoid it is already included in the end-of-line
module).
See figure
for connection details.
Configuration
Two zones must be associated with the extinguishing module.
When both zones are in alarm status the module will activate the
extinguishing pre-alarm warning siren (SP) and after a pre-defined
delay period (configured at the control panel) the solenoid output
and the warning optical panel will be activated.
The start extinguishing manual call point takes priority over the
control panel configuration – if a manual call point is activated the
extinguishing process will start.
The stop extinguishing manual call point may be only used during
the pre-alarm stage. Once extinguishing is activated this call point
has no effect.
Addressing
Each module requires a numeric address between 128 and 252 for
identification purposes. This is set using DIP switches 1-7 (see
Table 1: DIP switch address settings). DIP switch 8 is not used.

ESTING
Basic maintenance is reduced to a yearly inspection. Do not
modify internal wiring or circuitry.
Disconnect the detonator from the solenoid output
before testing to avoid emptying the gas bottle. After
the test the output must be rewired.
First test
Trigger an alarm via a detector in both zones associated with the
module and check that the extinguishing pre-alarm warning siren is
activated.

Second test
With the extinguishing process in pre-alarm activate a stop
extinguishing manual call point. Check that the extinguishing
process is not started.
Third test
Activate a start extinguishing manual call point and check that the
(PD);
extinguishing process is activated.
If the status LED and control panel fail to indicate the tests all
connections should be checked and the module address verified.

ESCRIPCIÓN
El KAL426C permite conectar y controlar una zona de extinción al
sistema de detección análogico.
El módulo incorpora 3 entradas vigiladas preprogramadas,
3 salidas vigiladas preprogramadas y un piloto indicador.
Las entradas son:
Abortar el proceso de extinción - pulsador de paro (PP)
Iniciar el proceso de extinción - pulsador de disparo (PD)
Vigilar la presión de las botellas .- presostato (PR)
Las salidas son:
Activar la electroválvula para la extinción – solenoide (SB)
Activar la sirena de prealarma de extinción (SP)
Activar el indicador luminoso de alarma de extinción (SL)
El piloto indicador esta encendido continuamente en alarma.
I
NSTALACIÓN
El módulo está pensado para ser instalado en el interior de
cualquier armario o caja de la instalación correspondiente y con
protección frente agentes medioambientales. La alimentación de
24 V debe tomarse de una fuente de alimentación auxiliar. El
proceso de instalación debe ser realizado con toda la instalación
sin alimentación.
Al final de todas las líneas de entrada/salida se ha de conectar
una resistencia de final de línea (4K7Ω) excepto en el presoestato
(PR) y en la solenoide (SB). En el presoestato la resistencia final
de línea no es necesaria y en la solenoide esta resistencia ya está
incluida en el modulo final de línea.
