The technical alarm mode reported by the MSG-45 module is indicated by the collective TECHNICAL
ALARM diode on the detection unit. It is also possible to read a technical alarm message (among other
messages) on the display.
During the control panel programming process, it is possible to assign individual technical alarm
messages to the universal monitoring lines (fK=11).
9.2.4 Fault mode (FAULT)
The MSG-45 fire extinguishing module detects and signals the following faults:
- break or short circuit in at least one monitoring line (LK1 ÷ LK11);
- break or short circuit in at least one output circuits of PK1 ÷ PK7 and PK8 ÷ PK16 relays (if the contact
monitoring function is active);
The fault mode is signalled by the control panel separately for each fire extinguishing zone by means of
the yellow collective FAULT diode.
9.2.5 Blockade mode (BLOCKADE)
The blockade mode signalled by means of the yellow collective BLOCKADE diode separately for each fire
extinguishing zone is present in the following cases:
-
at least one monitoring line (LK1 ÷ LK11) is blocked;
-
at least one relay (PK1 ÷ PK16) is blocked;
-
the EXTINGUISHING START procedure actuation is blocked (see 9.2.6);
-
the extinguishing agent discharge (DISCHARGE) is blocked (see 9.2.7);
-
non-electrical blockade supervised by the monitoring line fulfilling the "NON-ELECTRICAL
BLOCKADE" function is detected.
9.2.6 EXTINGUISHING START blockade
The fire extinguishing procedure actuation is blocked when the "EXTINGUISHING BLOCKADE" function is
active or there is a reason making its actuation impossible:
-
the EXTINGUISHING BLOCKADE is actuated in the control panel or on the MSG module
monitoring line to which the fK = 4 –EXTINGUISHING BLOCKADE function has been assigned;
-
the MSG module monitoring line with assigned fK = 4 –EXTINGUISHING BLOCKADE function is
faulty (short circuit, missing 10 kΩ end-of-line resistor);
-
the MSG module monitoring line input is blocked in the menu of the control panel to fK = 4 –
EXTINGUISHING BLOCKADE function has been assigned.
9.2.7 DISCHARGE blocking
1. After a fire extinguishing procedure is actuated, the discharge of the fire extinguishing agent
(EXTINGUISHING) is blocked when:
- the “EXTINGUISHING STOP" function is active or there is a reason making its actuation impossible;
- during the countdown of the extinguishing agent release delay time, the EXTINGUISHING STOP
push button is pressed (suspension) in the control panel or in the MSG module monitoring line to
which the fK = 3 – EXTINGUISHING STOP function has been assigned;
- the MSG module monitoring line with assigned fK = 3 –EXTINGUISHING STOP function is faulty
(short circuit, missing 10 kΩ end-of-line resistor);
- the MSG module monitoring line input is blocked in the menu of the control panel to fK = 3 –
EXTINGUISHING STOP function has been assigned.
2. an alarm output is blocked;
