ESCRIPTION
The KAL490 provides a remote input and a potential free voltage
relay output to an analogue fire system loop. The input signal is
constantly monitored and and its status displayed at the control
panel. The output is fail-to-safe. Auxiliary supply monitoring is also
included.
The output has three positions: Common (C), Normally Open (NO)
and Normally Closed (NC). In quiescent mode C and NC electrical
contacts are connected. When output is activated C is connected
to NO.
The input does not have polarity. When electrical contacts are not
connected the module remains in quiescent mode.
The status LED is lit constantly during alarm.

NSTALLATION
For general guidelines on fire system planning,
design, installation, commissioning, use and
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 power supply should
be disconnected during installation.
The 24 V power supply can be taken from the loop or from an
auxiliary power source.
If more than 10 KAL400 series modules are connected to a loop,
an auxiliary power supply is recommended. Always verify large

Power supply configuration
To set the module power supply remove the unit cover and
configure jumpers JMP1 and JMP2. See Figure 2: power supply

Do not connect a 24 VDC auxiliary power supply to
the module if power is supplied by the loop.
Addressing
Each module requires a numeric address between 128 and 253 for
identification purposes. This is set using DIP switches 1-7 (see
Table 1: DIP switch address settings). DIP switch 8 is not used.

AINTENANCE AND
Basic maintenance is reduced to a yearly inspection. Do not
modify internal wiring or circuitry.
To test the module:
•
Activate the input signal and check the activation message at
the control panel.
•
Activate the relay from the control panel and check the module
relay changes position.
If the status LED and control panel fail to indicate the test all
connections should be checked and the module address verified.
