VCP modules include the following:
• Voice Controller Assembly - This module performs all Voice/Tone
generation functions. The Voice Controller Assembly communicates with a
4020 Master and supervises amplifiers, microphones (Master and Remote)
and the VCP power supply. On-board switches provide simple audio
functions. This module also controls and supervises the 4003 SIGcard in
certain applications.
• 4003 SIGcard - This module allows supervision of four Class B circuits with
one signal circuit from a 4001, 4002, or 4020 (or any other reverse polarity
signal circuit operating at 24 VDC. It also accepts a +24V auxiliary alarm
input, and can be supervised by the Voice Controller Assembly. All four
signal circuit alarm relays energize with an alarm from the "host" signal
circuit (or VCP). A short or open circuit trouble on any of the four circuits
"open" the host signal circuit (or VCP trouble loop), causing the required
trouble indication at the host FACP.
• 4003 Class A SIGcard - This module is the Class A version of the 4003
SIGcard.
• 4003 Power Supply - Since this product can be used with a 4001-type
system, adequate power from the host FACP may not be available for audio
speaker circuit, DC signal circuit, and system use. This module is a linear
supply with brownout and battery charger features. Power supply capacity
is adequate for 75W Amplifier, VCP power, and battery charging. Battery
charging is limited to 18 Ah, so provisions are made to allow connection of
external battery power. The charger is disabled when external batteries are
used.
• 4003 Audio Amplifier - The 4003 uses a de-rated version of the 4100 Audio
Amplifier.
The 4003 VCP can be used in several different configurations:
• The 4003 can add voice and tone functions to a Simplex 4020 Fire Alarm
Control Panel (FACP) as a 4020 slave.
• The 4003 can operate as an adjunct to an existing fire alarm panel (such as a
4001/4002 or an FACP from another manufacturer).
• The 4003 can provide stand-alone operation as a paging system with a
manual selection of tones.
