EXXFIRE Installation and Service Manual 92
Manual Activation Button
When a Manual Activation Button (MAB) is connected to a system the configuration settings for this
system must be set accordingly (see section 5.5).
In case of connected systems this configuration setting must be made on the system to which the
MAB is connected. Example: in a configuration with 2 connected systems and a MAB connected to
the Slave system only, the configuration setting on the Slave system should be set for MAB
connected and the configuration setting on the Master system should be set for MAB not
connected.
In case configuration is set to no MAB connected nothing should be connected to the MAB input of
the EXXFIRE system so that the system sees open circuit on this input.
In case the MAB connection and MAB configuration settings do not match during system start-up or
when the MAB is in activated state during system start-up the system will show an MAB fault (code
CC on the 4-digit display of the UI panel). Make sure that MAB installation and configuration settings
match and reset the MAB before starting up the system.
When the system is in operation and the MAB is activated the ALARM LED on the UI panel will go ON
and the Alarm relay will be activated, resulting in the NO contacts of this relay to close. The buzzer
will go on (continuous sound). This is a count down to the start of fire extinguishment. The duration
of this count down is dependent on the configuration setting for Extinguishing Gas Delay (see 5.2)
and has a minimum duration of 0 seconds and a maximum duration of 15 seconds.
At the end of the count down fire extinguishing will start, indicated by a continuous sound. This
process is described in section 7.7.
The Alarm state will remain active even when the MAB is reset. The Alarm state can only be reset by
the procedure described in section 0.
Note: The PRE-ALARM 1 and PRE-ALARM 2 LEDs will not be switched on and the Pre-Alarm relay will
not be activated when the MAB is activated.
Door Switch
When a Door Switch (DSW) is connected to a system the configuration settings for this system must
be set accordingly (see section 5.5).
In case of connected systems this configuration setting must be made on the system to which the
DSW is connected. Example: in a configuration with 2 connected systems and a DSW connected to
the Slave system only, the configuration setting on the Slave system should be set for DSW
connected and the configuration setting on the Master system should be set for DSW not
connected.
In case the DSW configuration is set to “no DSW connected” nothing should be connected to the
DSW input of the EXXFIRE system so that the system sees open circuit on this input.
In case the DSW connection and DSW configuration settings do not match during system start-up
the system will show a DSW fault (code dd on the 4-digit display of the UI panel). When the DSW is
in open state during system start-up the system will show a Door Open fault (code EE on the 4-digit
display of the UI panel). Make sure that DSW installation and configuration settings match and close
the DSW (by closing the corresponding door(s) before starting up the system.
