Description and mounting of devices to output “Rel Fire”
Output
“Rel Fire” is a relay output with potential-free contacts, situated on the terminal bus:
–
normally open
“NO”;
–
normally closed
”NC”;
–
common point
“С”.
In Duty Mode there is a contact between terminals
“C” and “NС” of the relay.
In Fire condition, there is a contact between terminals
“C” and “NO” of the relay.
The output is not monitored for short-curcuit or interruption.
The relay contacts do not commutate 220V!
4.3.2.
Description and mounting of devices to output “Rel Fault”
Output
“REL Fault” is a relay output with potential-free contacts, situated on the bus terminal:
–
normally open
“NO”;
–
normally closed
”NC”;
–
common point
“C”.
The output is activated in Fault condition.
In Duty Mode there is a contact between terminals
“C” and “NO” of the relay.
In Fault condition, there is a contact between terminals
“C” and “NC” of the relay i.e. an output
device, commutated through the contacts of “REL Fault” will signal for fault condition in the system.
The output is not monitored for short-curcuit or interruption.
The relay contacts do not commutate 220V!
4.3.3.
Monitored outputs
“Out1” and “Out2”
Outputs are connecten on two-wire line for connection with the devices for sound and light
signalization.
The line is trimmed and monitored for interruption and for short-circuit.
In order to control the condition, it is necessary on the terminals of the signaling device to place
resistor 5.6
к
/ 0.25W.

On activation the monitored outputs supply voltage
(24±5) V. Maximum current load of the output
is
1А.
Outputs are programmable and can be activated in Fire mode.
In case of short circuit between “+” and “-“ the output activation will be disabled.
4.3.4.
Description and installation of devices to terminals of interface RS232/RS485
Interface RS232/485 is used for connection between the Control Panel and other intelligent
devices and PCs.
The connection between devices on RS485 is done by parallel connecting on two-wire line observing
the requirement, potential "A" and "
B” should not be crossed. The maximum distance between the
final devices is 1000 m. Regardless of the length of the line, on the first and on the last device, it is
necessary to put the jumper for line termination with 120
. For all other devices, the jumper must be
removed.
