4 – The MX43 Central Unit 17
B. Optional 24 VDX NiMH battery pack.
C. Terminal block for the analog card power supply.
D. Connector for the direct current external supply.
E. Battery fuse (4A) and external power supply (21 to 28 VDC, 3.2 to 4 A max.).
F. Connector for
-- Internal siren 24 VDC – 19mA max. and Sounder- terminals
- Internal flash 24 VDC – 40 mA max. Flash+ and Flash- terminals
G. Relays of alarms, from high to low Failure, R5, R4, R3, R2, R1.
- Failure: Non configurable failure relay
- R1 to R5: Configurable alarm relays
- Corresponding LED indicator: Lit when relay is under voltage.
Setting of alarm limits
The alarm limits governing relays R1 to R5 can only be set via the COM43 application. The
silkscreen image represents relays offline.
Relays R1 to R5 can be configured in positive or negative safety. Programming via COM43 in:
- Normal mode: Operation of the relay as per the normal alarm management (the relay is released
only if the event exceeds the duration of the time delay).
-Buzzer mode: The same as as in normal operation, with, in addition, the possibility of releasing
the buzzer relay even if the event is still present. The time delays are:
.Duration of maintenance: Minimum time of activation, adjustable from 0 to 900 seconds.
.Automatic release: Time adjustable between 15 and 900 seconds, beyond which the buzzer relay
is automatically released.
.Reactivation: Time adjustable between 15 and 900 seconds, beyond which the buzzer relay is
reactivated.
Alarm Relay Controls
-Logic equations of up to 4 levels of parentheses by the logic operators OR-AND, NOR-NAND.
The result of the equation controls the relay.
-Polling Operations (x over y): There must be at least “x” events over the total of “y” to activate
the relay. Optionally, the user may define whether a failure is considered an event in the same
category as an alarm.
