BEFORE INSTALLING
Please read the System Smoke Detectors Application Guide, which
provides detailed information on detector spacing, placement, zoning,
wiring, and special applications. Copies of this application guide are
available from System Sensor. Before installing and using the product,
please read the system wiring and installation manual thoroughly.
If the products will be installed in an existing operational system,
inform the operator and local authority that the system will be
temporarily out of service, disconnect power to the control panel before
installing the products.
This isolator base must be installed in compliance with the control
panel installation manual and meet the requirements of the authority
having jurisdiction. The installer must be familiar with these
requirements, with local codes, and any special requirements of the
authority having jurisdiction.
NOTICE: This manual should be left with the owner/user of this
equipment.
GENERAL DESCRIPTION
There is an automatic switch in the product that opens when the line
voltage drops below 4 volts. It is used to isolate the detector which is
connected in the communication line. In the event of a short circuit
condition on the communication line in the detector, the isolator base
will open its switch and disconnect the detector from the
communication line. When the short condition is removed and the line
voltage rises above 7 volts, the isolator base will detect the removal of
the fault condition and automatically reconnect the isolated detector.
Refer to Figure 1.
Remove power from initiating-device circuits before installing the
isolator base.
MOUNTING
Mount the detector base directly to a 4-inch square with plaster ring,
or a 3.5-inch octagon box.
Mounting hole spacing is 50mm, 60mm and 70mm, symmetrical
center.
WIRING INSTALLATION GUIDELINES
The B501BI-IV isolator base is intended to use in an Intelligent System,
There are five terminal blocks on the base (
Refer to Figure 1).
'COM+' = Positive power supply input / output
'COM-' = Negative power supply input / output / Negative
remote annunciator output
'OUT+' = Positive power supply output
'RA' = Positive remote annunciator output
For signal wiring (the wiring between interconnected detectors and
modules), it is recommended that the wiring be no smaller than 18
AWG (0.823 square mm). Wire sizes up to 12 AWG (3.31 square mm)
may be used with the base.
Note: Refer circuit wiring diagram Figure
2.
Note: Please dispose electronic waste following national or local
regulations after being scrapped or replaced. Do not discard.
