1)
POWER indicator of the equipment.
2)
FAIL contacts
Output relay used to indicate a system failure.
If the COM contact is linked to the NO contact, it indicates that there
are no faults or alarms in the system. If on the other hand, COM is linked
to NC, it indicates that the equipment is switched off or alarms detected
(figure 4).
Maximum DC charge current: 150mA
Maximum DC or AC peak charge voltage: 350V
BUS
3)
CAN contacts
Data communication bus between the COMPACT matrix, the
COMPACT-E expansion unit and CAN peripherals.
For the connection of the CAN bus it is recommended to use a shielded
twisted pair AWG24 cable. See section 5.3. Connection between the
COMPACT and COMPACT-E units and 5.4. Connection between
COMPACT and CAN peripherals.
4)
OUTPUT CT contacts
It has three output contacts. Each contact consists of two terminals (A
and B) that can be configured, by means of internal DIP switches as dry
contacts (with or without 3K3 resistor) or referenced to ground (contact
A). For configuration follow figure 7 on the next page.
The functionality and the idle state (NC/NO) are configured via the Call
Point software. They can be configured as general-purpose contacts, or
in evacuation systems as fault notification contacts, Emergency Mode
activated indicator....
To connect as dry contacts, follow figure 5. If contacts referenced to
ground are desired, follow figure 6.
Attention: Max. DC charge current: 150 mA. Max.
DC or AC peak charge voltage: 350 V.
