EN: Installation instructions
Description
The KAL790 provides a remote input and a potential-free
voltage relay output to an addressable fire detection system.
The input signal is constantly monitored and its status
communicated to the fire 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 standby the C and NC
contacts are connected. When the output is activated the C
contact is connected to the NO contact.
The input is polarity insensitive. When electrical contacts are
not connected, the module remains in standby mode.
Note: The input state is latched (this is not configurable) and
returns to standby after a system reset.
The module may be used with any device and the choice of
contact used (C, NC or NO) will set the desired event.
Installation
Caution: For general guidelines on system planning, design,
installation, commissioning, use and maintenance, refer to the
EN 54:14 standard and local regulations.
Module installation
