10 Use in Fire Alarm Systems
The HIMatrix systems may be used in fire alarm systems in accordance with DIN EN 54-2
and NFPA 72, if line monitoring is configured for the inputs and outputs.
In this case, the user program must fulfill the requirements specified for fire alarm systems
in accordance with the standards previously mentioned.
The maximum cycle time of 10 seconds required by DIN EN 54-2 for fire alarm systems
and the safety time of 1 second (fault reaction time) required in certain cases, can be easily
met since the cycle times for these systems reside in the millisecond range.
According to EN 54-2 the fire alarm system has to be in the fault report state within
100 seconds after the HIMatrix system has received the fault message.
The fire alarms are connected using the energize to trip principle with line monitoring for the
detection of short-circuits and open-circuits. To this end, the following devices and modules
may be used:
 The digital and analog inputs of the F35 controller.
 The analog inputs of the F3 AIO 8/4 01 remote I/O.
 The digital inputs and outputs of the F3 DIO 16/8 01 and F3 DIO 8/8 01 remote I/Os.
 The AI 8 01 and MI 24 01 input modules of the F60

resistors must be calculated as dictated by the
sensors in use and the number of sensors per detection loop. Refer to the data sheet from
the sensor manufacturer for the necessary data.
The alarm outputs for controlling lamps, siren, horns etc. are operated in accordance with
the energize to trip principle. These outputs must be monitored for short-circuits and open
circuits. This can be done by returning the output signals directly from the actuator to the
inputs.
The current in the actuator circuit can be monitored via an analog input using an
appropriate shunt. Z-diodes and series resistor connected in series protect the input against
overvoltage if a short-circuit occurs.
For an explicit detection of open-circuits (with de-energized DO outputs), a transmitter
supply is required in addition to the analog inputs (see draft below):
