Short Circuit Isolator - Panasonic 4466 Technical Description

4466 EXTERNAL POWER SUPPLY - FIRE ALARM SOLUTIONS TECHNICAL DESCRIPTION
4.7.

SHORT CIRCUIT ISOLATOR

The external power supply, 4466, has a built-in short circuit isolator that requires no separate COM loop address. Like any other
short circuit isolator, it will be given an individual sequence number when programmed in EBLWin or via automatic addressing
function.
For systems ≤ EBL512 G3 2.2.x: The isolators must be connected consecutively regarding sequence number 00-127, in the COM
loop's A-direction.
For systems ≥ EBL512 G3 2.3.X: The sequence numbers can automatically be generated and sorted consecutively in the COM
loop's A-direction. Function "Arrange sequence numbers" in EBLWin must be activated. (Tools/Options/EBLWin Settings).
Parameter
The maximum line voltage
The nominal line voltage
The minimum line voltage
The maximum rated continuous current with the switch closed
The maximum rated switching current on short circuit conditions
The maximum leakage current with the switch open
The maximum series impedance with the switch closed
The maximum voltage at which the device isolates
(i.e. close to open)
The minimum voltage at which the device isolates
(i.e. close to open)
The maximum voltage at which the device will change
from open to close.
The minimum voltage at which the device will change
from open to close.
1) The device can change from open to close by commands from the control and indicating equipment only. This can be done at minimum to maximum line
voltage, i.e. 12V DC – 30 V DC.
For more information on short circuit isolators, see the Planning instructions for EBL128 or EBL512 G3 version 2.3.x or later.
