GENERAL DESCRIPTION
The System Sensor ISO524-1 short circuit isolator is designed for use
with all 200 and 500 series analogue addressable detectors and modules.
They prevent an entire communications loop from being disabled when a
short circuit occurs. They accomplish this by isolating that part of the loop
containing the short from the remainder of the circuit. These isolators
also automatically restore the entire loop when the cause of the short
circuit is corrected. The isolator has been designed such that if the short
circuit occurs between adjacent ISO524-1 and / or B524IEFTx units, and
no other products are connected between, the operation of the entire
loop will remain intact in the event of this one short circuit, dependent on
control panel operation.

The ISO524-1 Isolator may be installed in various convenient locations,
such as junction boxes, behind sensor bases, within callpoint back-
boxes, or within SMB500 module boxes.
INSTALLATION GUIDELINES
( + )
All wiring must be installed in compliance with all applicable local codes
and any special requirements of the local authority having jurisdiction,
using the proper wire sizes. The conductors used to connect smoke
detectors to control panels and accessory devices should be colour-
coded to reduce the likelihood of wiring errors. Improper connections can
prevent a system from responding properly in the event of a fire.
For signal wiring (the wiring between interconnected detectors), it
is recommended that the wire be no smaller than 0.5 mm
wire sizes up to 2.5 mm
cable connectors. The use of twisted pair wiring or shielded cable for the
power (+ and -) loop is recommended to minimize the effects of electrical
interference.
If shielded cable is used, the shield connection to and from the isolator
must be continuous by using wire nuts, crimping, or soldering, as
appropriate, for a reliable connection.
Alarm system control panels have specifications for allowable loop
resistance. Consult the control panel specifications for the total loop
resistance allowed before wiring the detector loops.
1. Using suitable cable connectors, connect the incoming and outgoing
loop positive cables to each of the two available Red ISO524-1 cables.
2. Connect the Yellow cable to Device +ve, in order to maintain device
+ve irrespective of the position of the short circuit (Fig 2b), otherwise
do not connect (Fig 2a).
3. Connect the incoming and outgoing loop negative cables to the single
Black ISO524-1 cable .
4. Check the entire loop wiring before applying power. This includes
checking the wiring for continuity, correct polarity and ground fault
testing.
5. Once all loop cabling has been checked, power may be applied to the
system and functional tests carried out.
