BX-ESLEnd switch module eXtended forSecuriLine eXtended

from edition 20-00007-01-011

The BX-ESL end switch module eXtended Linecommunicates

the position of the actuation rod using an internal light barrier.

The state active/passive is reported to the FAS and indicated

on the BX-ESL with a LED.

It meets the specifications of SecuriLine eXtended for operation

on the ring circuit of the SecuriFire fire detection system.

Description

The BX-ESL can be connected to the SecuriLine eXtended ringcircuit of the SecuriFire 1000/2000/3000 fire detection systems.

Typical applications include sprinkler monitoring and blocking

equipment.

The BX-ESL measures the movement of an actuation rod by

means of an infrared light barrier. This realises the function as

limit switch.

On the front, a multi-colour LED can indicate an end position of

the rod in either red or yellow.

Addressing and assigning BX-ESL parameters is performed with

PC software via the fire alarm control panel.

The BX-ESL includes a short-circuit isolator. In the event of wire

breakage or short-circuit this functionality ensures that the fault

is localised and that operation of the ring circuit remains fullyfunctional.

The BX-ESL is built into a plastic switch housing. The cables are

led in through PG screw fittings.

The SecuriLine eXtended is connected via the X1-X4 screw ter-

minals.

ProgrammingSecuriFire software documentation is planned for programming and

planning.

Power requirementFor mixed operation of detectors and modules on the ring circuit, it is

important to know that the BX-ESL has the power consumption of

about 4 detectors. This reduces the number of connectable detectorsby 4 for each BX-ESL in use. A maximum of 32 BX-ESLs are permit-

ted per ring circuit.

A tool is available for calculating the maximum possible ring length

and the maximum number of participants.
