Section 1-4 - Property Insurance Recommendation

The SAFEPATH® panel is not a substitute for insurance. All users should have adequate levels of
life and property insurance

.

Section 1-5 - Audio Output Considerations

! Warnin

! Caution:

If live microphone announcements, audible tones and/or voice messages cannot be readily heard and
understood clearly within the protected areas as intended, it will be necessary to increase the number
and/or sound output intensity of speakers within those areas so that they are heard and understood

clearly when activated

AUDIBLE SIGNALS MAY MASK MEDICAL EQUIPMENT MONITORING
ALARMS. WHERE MEDICAL EQUIPMENT MONITORING ALARMS ARE IN
USE, DO NOT USE AUDIBLE SIGNALS; PROVIDE VISUAL NOTIFICATION
APPLIANCES IN HIGHLY VISIBLE LOCATIONS.

The output of the audio system may not be heard in all cases. Sound can be
blocked or reduced by walls, doors, carpeting, wall coverings, furniture,
insulation, bed coverings, and other obstacles that may temporarily or
permanently impede the output of the audio system. Sound is also reduced
by distance and masked by background noise. The output of the audio
system may not be sufficient to alert all occupants, especially those who are
asleep, those who are hearing-impaired, those who are wearing devices that
plug or cover the ears, and those who have recently used drugs or alcohol.
The output of the audio system may not be heard by an alert person if the
output device is placed in an area which is isolated by a closed door, or is
located on a different floor from the person in a hazardous situation or is
placed too far away to be heard over ambient noise such as, but not limited
to, running water, traffic, air conditioners, machinery or musical appliances

.

.

1-3

Section 1-6 - RF Interference

The SAFEPATH® Panel has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed and
used in accordance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at the user’s own
expense.

Section 1-7 - General

Each manufacturer's fire alarm control panel, and notification appliances operate differently and have
different features. Before specifying, installing, operating, testing, maintaining or servicing a system,
carefully read the installation, operation and testing manual for each piece of equipment and
applicable codes.

The lives of people depend upon your safe and proper installation of the SAFEPATH® Panel. Please
read, understand and carefully follow the specific installation instructions set forth below to avoid
damage to the SAFEPATH

Wiring Guidelines

Although the SAFEPATH® Panel products incorporate signal verification and noise filtering circuitry
on their inputs, induced voltages or noise on the input wiring can cause improper operation.
Therefore, use shielded twisted pair wire for all dry contact input wiring.

Wire gauge may vary for each visual notification appliance output circuit on the panel. Wire gauge
selection should involve consideration of all factors including, wire loop length, maximum current draw
of each appliance, number of appliances, and maximum voltage drop allowable.

When laying out each NAC circuit for the speakers, calculate the total wattage required. Good
engineering practice is to not exceed 85% of the amplifier rating that you plan to use. If calculations
exceed this, an larger capacity amplifier or additional amplifier(s) can solve this problem.

• Each Strobe NAC has a 24 VDC, 2.0 amps maximum output

• Each Strobe NAC meets Class B supervision requirements for notification appliance

circuits.

• Each output circuit shall have a UL LISTED, 10K Ohm, EOLR resistor. (1W), installed
across the last visual notification appliance. If the output is unused, a UL LISTED,
10K Ohm, EOLR resistor (1W) shall be placed across the output terminals. Each
amplifier module contains the required number of EOLRs for the supervised outputs.
If more are needed, recommend using Wheelock, Inc. End of Line Resistor Kit
(Model Number EOLK, Part# 5076), which contains Eight (8) UL LISTED 10K Ohm

Central Amplified Speaker Notification Appliance Output Wiring

Wire gauge may vary for each audio appliance output on the panel. When:

• Speaker (with transformer) appliances are used with supervised audio amplifier
module (central amplified outputs). Wire gauge selection should involve
consideration of all factors including, wire length, appliance power ratings, and the
number of appliances.

• The central amplified output is either a selectable 25, 70.7 or 100 volt audio output,
rated for 40, or 80 watts maximum, depending upon the amplifier and its
configuration.

• The output meets Class B supervision requirements for notification appliance circuits.

• Each output circuit shall have a UL LISTED, 10K Ohm EOLR resistor (1W) installed

across the last audio notification appliance. If the output is unused, it shall have a UL
LISTED, 10K Ohm EOLR resistor (1W) across the output terminals. Each amplifier
module contains the required number of EOLRs for the supervised outputs. If more

Amplified Speaker Notification Appliance Power Output Wiring

Wire gauge selection for the amplified speaker notification appliance power output should involve
consideration of all factors including wire loop length, maximum current draw of each appliance,
number of appliances, and maximum voltage drop allowable.

• The Speaker Amp (SPK AMP) output is rated for 24 VDC, 2.0 amps maximum.

• The output meets Class B supervision requirements for notification appliance

circuits.

• The amplified speaker output is 15 Ohms, -5dBm maximum.

• Each output circuit shall have a UL LISTED, 10K Ohm EOLR resistor (1W)

installed across the last appliance. All unused outputs shall have a UL LISTED,
10K Ohm EOLR resistor (1W) across the output terminals. Each amplifier module
contains the required number of EOLRs for the supervised outputs. If more are
needed, recommend using Wheelock, Inc. End of Line Resistor Kit (Model
