−
Terminals “Rel1/C”, “Rel1/NO”, “Rel1/NC”, “Rel2/C”, “Rel2/NO” and “Rel2/NC” – potential free
relay contacts, responding at Fire condition (in compliance with the pre-programmed relation
fire
alarm line – relay outputs
);
−
Terminals “REL Fault/C”, “REL Fault/NO” and “REL Fault/NC” – potential free relay contacts.
When no fault condition is detected terminals “REL Fault/C” and “REL Fault/NO” are
connected; upon detection of fault condition terminals “REL Fault/C” and “REL Fault/NC” are
connected.
The executive device shall be connected according to Appendix 6b.
Unused relay outputs remain unoccupied.
17.3. Connecting interface devices
17.3.1. Global network
Connection of interface devices to the global network is made via serial interface RS232, using 9-
lead coupling (Appendix 4). Signals distribution is given in Table 3.

The fire control panel provides power supply to an external modem, if the feature has been
included in the customer’s order. The power supply is tapped on a two-pole terminal on the PCB
Power supply to modem.
17.3.2. Local network
Connection of interface devices to a local network is made via two serial interfaces CAN 2.0B
using the terminals CAN1 and CAN2.
17.4. Connecting addressable fie detectors
Addressable fire detectors are connected to the fire control panel by means of two-wire insulated
line of total resistance up to 100
Ω
(Appendix 5a). Connection is made to the terminals of the
corresponding fire alarm loops (Appendix 4) observing the indicated polarity (N is the number of othe
loop).
−
“+LoopN-1”, “-LoopN-1” and „
:
” for the beginning of the loop;
−
“+LoopN-2”, “-LoopN-2” and „
:
” for the end of the loop.
In one fire alarm loop a maximum of 125 addressable devices can be included regardless of their
type.
Unused fire alarm loops remain free (no connection is made to their terminals).
It is recommended to include addressable devices in closed fire alarm loops (Appendix 5b). If
branches of the loop (Apendix 5c) are to be used, the following restrictions shall be observed:
−
do not connect a branch between the control panel and the first/last device in the loop
(Appendix 5d);
−
do not connect two or more branches between two consecutive devices in a loop (Appendix
5e).
Addressable output modules supplied by the power loop shall be connected to it by means of two-
wire insulated line of total resistance not more than 10
Ω
(Appendix 5a). Connection is made to the
terminals of the power loop (Appendix 4) observing the indicated polarity:
−
“+PowerL-1” and “-PowerL-1” for the beginning of the loop;
−
“+PowerL -2” and “-PowerL -2” for the end of the loop.
