Analog base with isolator 4313

•Common base for the different analog detectors

•Built-in short circuit isolator

•Easy connections incl. output for external LED

Common base

The analog base 4313 is connected to a COM loop. Any analog heat, smoke and multi detector types 33xx / 430x can be plugged in the base. (For required type of base, see Product Leaflet for the detector type respectively.)

Short circuit isolator

The analog base 4313 has a built-in short circuit isolator with the same functions as the Addressable short circuit isolator 4370.

The short circuit isolator will divide the COM loop into segments. A segment is the part of a loop between two isolators or between one isolator and the c.i.e. In case of a short circuit on a COM loop, only the affected segment will be disabled, i.e. the number of disabled loop units is minimised. All other loop units will continue to work normally. Up to eight isolators (4313 and/or 4370) can be connected on each COM loop.

Easy connection

The base has screw terminals for the COM loop (in/out) and an external indicator (LED), e.g. 2218.

COM loop address

The COM loop address for the isolator is set with an Address setting tool 3314, which is also used to set the mode:

NORMAL mode: Short circuit isolator 4313 in system EBL128.

2330 mode: Short circuit isolator 4313 (2370/4370 in Win512) in system EBL512.

2312 mode: Not used for 4313.

Miscellaneous

The base has an address label (Al) where the detector's and isolator's COM loop addresses can be written.

Individual fault signal is obtained if wrong type of detector (compared with the programming) is plugged in the base or if the detector is unplugged. A short circuit or a single break (cut-off) on the loop will generate a fault and a fault message, e.g. short circuit or break, COM loop number and between which isolators.

For more information regarding detector types, connections, etc. see Planning Instructions and connection diagrams for the system respectively.

Label holder

An optional label holder could be mounted in the base (in the label holder recess) and is intended for a label showing "zone-address" etc. Can be read also when the detector is plugged in the base and is ceiling mounted.

Product applications

Used in the systems EBL512 / 128 to increase the COM loop safety.

The base is intended for indoor use and in dry premises.
