Terminology used in this manual
Term Definition
Approved See certified.
Branch Loudspeaker line between an Isolator Board tap-off and the last
loudspeaker connected to the tap-off.
Certified Means designed and built to conform (compliant) to the stated
standard or guideline, and additionally tested and certified by an
accredited notified body.
Compliant In the framework of this manual, means designed and built to
conform (compliant) to the stated standard or guideline.
Fault isolation time The time required by the Isolator Boards to isolate a fault. This
includes the time required to restore audio to the non-affected
parts of the loudspeaker line after detection of a fault. In the
Loudspeakers Line Isolator System this time is always less than
4 seconds.
Fault recovery time The time required by the Loudspeakers Line Isolator System to
return to the normal OK state after a detected fault has been
corrected (< 100 s).
Fault reporting The loop fault indication LED lights up, and the corresponding loop
fault and general relay go to the NOK state on the Master Unit
(< 90 s).
Fault reporting time The time required by the Loudspeakers Line Isolator System to
report a fault (i.e. time required to go to the fault warning
condition).
Initialization The first state that the Loudspeakers Line Isolator System goes to
after system start up. The system takes a maximum of 10 seconds
to initialize the loop.
Loop Redundant loudspeaker line. All loudspeakers broadcast the same
signal. A loop has a dedicated input signal from the zone output of
the public address/voice alarm system at loudspeaker level. Some
standards limit the number of alarm zones in a loop (e.g. a limit of
25 loudspeakers if each zone has one loudspeaker).
Loop recheck While the Loudspeakers Line Isolator System is in a fault condition,
regular rechecks are performed to check the condition of the loop.
Loudspeaker line The loudspeaker line between the Master Unit (loop out and loop
return) and the loudspeakers, including the line to the
loudspeakers on the tap-off.

Referred to in this manual as “DC Blocking Board” - circuit board
that has the same connections as the Isolator Board, which allows
for quick and convenient connection of the loudspeaker loop and
tap-off connections.
Segment The wire and/or group of loudspeakers between two Isolator
Boards and between the Master Unit and an Isolator Board.
Voice alarm zone Geographical part of an evacuation zone in which an evacuation
alarm is carried out. Alarm zones are defined per installation.
Walk Test Test mode for checking the loop by feeding the power and signal
from one side of the loop only.
Zone An area where the same signal is broadcast that can be separately
addressed by the public address system.

System overview
The Loudspeakers Line Isolator System is the cost‑efficient solution for preventing loss of
audio function in public address and voice alarm systems as a result of loudspeaker line faults.
It largely eliminates the need for expensive E30 cabling by making use of the so‑called loop
wiring method. The system is fully supervised and is perfectly suited for use in commercial
premises, such as office buildings and hotels.
Typical applications include:
– Public address systems that cover large zones: more than 25 loudspeakers per zone.
– Voice alarm: locations that have several rooms in the same fire zone.
The Loudspeakers Line Isolator System consists of the following products:
PM1‑LISM6 - Loudspeaker Line Isolator System Master
Referred to in this manual as Master Unit:
The Master Unit is the main component of the Loudspeakers Line Isolator System. The zone
outputs of the public address/voice alarm system are connected to the Master Unit. Each
Master Unit has connections for six loudspeaker loops. Each loudspeaker loop can manage
500 watts. A maximum of 50 Isolator Boards can be installed in each loudspeaker loop.
The front panel on the Master Unit has LEDs to indicate:
– The status of each loop.
– The status of the mains and back-up battery power supplies.
All fault indicators on the front panel are linked to fault relays on the rear panel.
PM1‑LISS - Loudspeaker Line Isolator with Housing
Referred to in this manual as Isolator Board:
The Isolator Board has two 100 volt audio connectors for connecting to both sides of the
loudspeaker loop and a third 100 volt audio connector for creating a tap-off for one or more
loudspeakers. Jumper settings are provided to set the permissible loudspeaker power level
(10, 36, 100 watt, or 10 watt with 20 kHz pilot tone filter), and other supervision settings.
