EXXFIRE Installation and Service Manual 20
Configuration settings
The system has an array of DIP switches and a rotary switch for installer level configuration settings
for the following functions:
- Smoke sensitivity setting
- Extinguishing gas delay (time delay between Alarm and release of the gas)
- Time delay between gas release of multiple generators (only applicable for EXXFIRE
®
1500CNF or 2250CNF)
- Flow monitoring sensitivity
- Configuration of Manual Activation Button
- Configuration of Door Switch
- Configuration of connected systems
The configuration settings are described in detail in Chapter 5.
Power Supply and battery back-up
The EXXFIRE
®
750CNF/1500CNF/2250CNF series are equipped with an internal power supply unit
and battery back-up that complies to EN54-4. The system can be powered by mains power 100/240
Vac. The battery back-up function allows continuation of system operation for 12 hours in case of
mains power interruption (based on fully charged battery).
Availability of mains power and battery status and health are monitored, and fault status is
activated in case of power interruption or battery problems.
Connection of multiple systems
An EXXFIRE
®
750CNF/1500CNF/2250CNF system can operate as a standalone system to protect
volumes up to 1.5/3.0/4.5m
3
.To allow protection of larger volumes, the EXXFIRE
®
750CNF/1500CNF/2250CNF series are designed to enable connection of multiple systems (with a
maximum of 8) to protect volume up to 36 m
3
for 8 connected EXXFIRE
®
2250CNF systems.
Connected systems will functionally behave as one system: fire detection, gas release and system
alarm and fault status are synchronized for all connected systems. Each of the connected systems
is equipped with a smoke aspiration system, allowing multiple smoke detection points in the
protected volume. In case one of the connected systems generates a Alarm all systems will deploy
their gas simultaneously. A common system status (fault, pre-alarm and alarm status) is available
on the relay outputs, so that only one of the systems (the Master system) needs to be wired to a fire
alarm panel.
A RS485 communication bus is used to connect systems into a Master-Slave configuration, with one
Master system and up to 7 Slave systems. The systems are physically connected by a shielded fire
alarm cable. One of the connected systems will be configured as Master System and the others as
Slave Systems. A number of DIP switches and a Rotary Switch are provided for Access level 3
configuration settings.
The settings are described in Chapter 5.
