4 Installation
4.1 Introduction
Remember, the lives of people depend upon the safe and proper installation of the voice evacuation system and
the SP40S Multi-Function Facility Communication System. Please read, understand, and follow the specific
installation instructions set forth in this chapter carefully to avoid damage to the panel and equipment connected
to it. Ensure that only qualified personnel in accordance with the procedures in this manual conduct the
installation.
WARNING: Shut off all power before starting the installation. Electrical
shock can cause death or serious injury.
WARNING: Do not connect AC power or battery backup power until system
wiring has been connected, modules have been installed, and field wiring has been
inspected.
CAUTION: The SP40S printed circuit board is sensitive to static electricity and has delicate
components mounted on it. Before handling the board or any component on it, discharge any
static electricity from your body by touching a grounded object such as a metal screw, which is
connected to earth ground. Install the panel in a static-free area; properly attach grounded
wrist straps before touching any static-sensitive areas.
• If you or the installer have any questions about the installation, consult with the authorities having
jurisdiction (AHJ), prior to installation.
4.2 Fire Alarm Control Panel Wiring Applications
The SP40S Digital Voice Section inputs and the strobe input require an 8 to 33VDC. The Fire Alarm Control
Panel (FACP) NAC Circuit of 12VDC or 24VDC initiates this circuit.
TROUBLE Form C relay terminals and an internal sounder are available for monitoring the condition of the
SP40S Multi-Function Facility Communication System.
