Description

The SP40S is a Multi-Function Supervised Paging, Messaging,
Background Music delivery and Emergency Voice Evacuation
System with 24 VDC battery backup. This single channel
system is capable of delivering 40 watts of supervised high
fidelity audio power and 2 amps of supervised 24 VDC
synchronized strobe power. It comes standard with an
on-board digital voice messaging system with 8 standard
messages, a hand-held microphone, power supply/battery
charger and numerous additional features. The SAFEPATH4
system is expandable to 5280 watts utilizing the SPB-80/4 (80
watts and 4 amps of strobe power), the SPB-160 (160 watts)
or SPB-320 (320 watts) supervised audio power boosters. All
models available in 115 VAC ir 220 VAC.

Applications for the SP40S

• Multi-use applications—The system can function as an
evacuation system, an emergency messaging system,
a paging system, an employee notification system and a
background music system per NFPA 72 (2002), section

6.8.4 Combination Systems

• Fire code applications—The system is listed under UL
Standard 864, 9th edition delivering supervised audio and
voice messaging with strobes and notification appliance
circuits (NAC) for visual alerting

• Economic OSHA applications—The system is OSHA

1910.165 compliant; this means that it does not require
reliability inspections every two months, or the required
spare parts inventory

• Wide ranging applications—from small to large facilities

• Can connect to pagers for private alerting of emergency/

trouble conditions

System Activation

• Contact closure message activation

to accommodate large installations with supervised audio
power and also supervised and synchronized strobe power
requirements.

The SPB-320 draws 2.4 watts of audio input power to
properly operate and provide additional supervised audio
output power. The SPB-160 and the SPB-80/4 draws 1.2
watts of audio input power to properly operate and provide
additional supervised audio output power. A maximum of
5,280 watts of supervised audio power can be achieved.
Additional strobe power can be obtained via a combination
of SPB-80/4 or Wheelock Power Supplies/Chargers.
