BSR-7071/A Line Isolator
GENERAL
The line isolator is a bidirectional non-addressable loop monitoring device for addressable fire
detection system’s loops. It is installed on the Addressable Loop, powered by the Loop and
monitors continuously the voltage levels and the signal’s integrity. The main supported function
is to isolate a portion of the loop (between the two closer isolators) in the event of a short-
circuit. In case of two short circuit events, only the detectors before the first and after the
second short circuit are powered. Repair of the short circuit condition brings the loop condition
back to normal automatically (closed loop). Location of the short circuit position is achieved by
reading the lost address detectors attached on the top of each isolator. We can have up to 4
additional detectors-devices connected and controlled on a single isolator output (A and B
topology).
It is advised to apply up to 3 additional devices on the output of each isolator (4 detectors or 4
call points or 2 sirens). Maximum resistance between isolators in each loop, should not exceed
the 1,5Ohm. The consumption of the isolator must be considered in modification of existing
loops, to reduce by one the number of the detectors in full load loops. We can have up to 50
paired units (50 isolators + 50 detectors). For systems with more than 50 paired units, reduce
by one the detectors for every three added isolators.
The reasons that an isolator device is isolating are stated below.

Electrically, the attached detectors are connected to the output of each isolator. This is why
regardless the isolator state it is possible the attached detectors to be operational, like the
above two topologies (Α and Β).

Instructions to the installer.
Reasons that lead to isolation
1. Short Circuit condition
2. Wrong Polarity on Input Output terminals
3. More than 3 devices connected on the isolator output
4. Increased losses on the loop wiring
5. Protocol integrity faults
Installation - Comments
1. Regardless the isolator’s condition on the -L wiring there is electrical continuity.
2. By hardware, the attached detector is powered automatically from the output side terminal of the
isolator, simply rotating itself on the isolator. It is advised the electrical connection of each isolator
on the loop, to comply the input / output markings so that in short circuit condition “only one”
detector to be out of order.
3. When connecting the isolators in the loop, the first and the last isolator should be connected to the input
terminal (+ L-L INPUT). There will be two intermediate isolators linking output to output. The non
compliance of input/output process during electrical installation, is found in case of short circuit
condition with all detectors operational. In this case, detection of the location of the short circuit
cannot be achieved from location of the “lost detector’s address” but on step by step short circuit
wiring check process from the qualified technician- installer.
4. We remind that power loss of a loop leads to isolated condition of all isolators.
5. The loop is Time and Isolator controlled which means it takes at least (0,5sec * number of the
installed units) time to change from open loop condition to close loop condition where all devices
are available to the main panel for scan and registration.
6. Avoid to connect more than 4 additional units on the output of the isolator (4 detectors or 2 sirens
or 3 call points) between two isolators. The device may inhibit the output from power considering
increased cable losses. Maximum resistance between isolators in each loop, should not exceed
the 1,5Ohm.
7. Overcome of problem case (6) due to output overload, is achieved by running Reset command
on main panel. With this command we provide the ability of temporary (until next short circuit
detection) loop powering, enabling the installer to modify the loop structure easily.
8. Like all loop powered devices, with Reset command the isolator is forced to reset condition.
9. It is possible during the restore of a short circuit condition, the main panel to read more than one
addressable devices with the same address. Since the restore condition is a transient condition of
loop extension and repair process, it is advised to execute a Reset command with automatic
identification of all address devices before any thoroughly inspection check of each address point.
10. In the output of the isolator (on the wiring) we have the following AC measurements :
a. Below the value of 2V voltage difference in case of short circuit (assumed open loop)
c. Below the input voltage difference in case of load charging process (assumed open loop)
c. Equal to input voltage difference for set condition (assumed closed loop)
11. There is no extra action from the installer to connect / disconnect a detector on the isolator,
except the simple rotation action like the normal basis. The operation of the isolator is the same
regardless the presence or not of the detector.
