Technical and System Information for EN54-13 Compliance
NODE+ 1Loop, 2Loops, 3Loops e 4Loops
●
It is not allowed to run the loop out and loop return conductors on the same cable.
●
It is mandatory the use of class A topology
●
The panel is limited to address a maximum of 125 addressable devices per loop, but sometimes can be less
because some devices require multiple addresses (3 I/O PLUS and QUAD ZMU).
●
A maximum of 20 addressable sounders can be fitted on each loop.
●
Each loop is limited to draw a current, in nominal operating condition, of 150 mA in quiescent mode.
●
Each conventional sounder output is limited to drive a current of 250 mA in fire alarm condition.
●
A maximum current of 300 mA can be drawn on the DC AUxiliary Supply Output.
Table 1 - NODE+ 1 Loop, 2 Loops, 3 Loops and 4 Loops, IOs and TPs specifications.
POWER SUPPLY UNIT - ORION BCM
●
A maximum current of 300 mA can be drawn on the DC Auxiliary Supply Output.
Table 2 - ORION-BCM, IOs and TPs specifications.
Cabling
●
Where shielded cable is required a cable with internal resistance less than 15 Ohm/Km is mandatory.
●
Cable shield continuity should be performed inside the device enclosure.
3 I/O PLUS 1/2/3 Channels and MAINS I/O
●
For fire condition each input TP shall see a resistance between 2,2 kΩ and 8,2 kΩ.
●
For open condition each input TP shall see a resistance higher than 47 kΩ.
●
For short circuit condition each input TP shall see a resistance lower than 2,2 kΩ.
●
LOOP IN/OUT the limitations of the GEKKO panel are applicable for the same TP.
