4 Installation
To connect without an external power supply:
–
Mount the module(s) inside the control panel enclosure. You can use any mounting
position.
– Use a UL Listed tamper switch on the enclosure in a commercial burglary application.
– If installing the module in a separate UL Listed enclosure, install the enclosure according
to the manufacturer’s instructions.
– For UL fire applications, mount the module within 20 ft (6 m) of the control panel
enclosure with the wiring in conduit between the two.
– For multiple modules, you can connect up to twelve modules to the same supervision
point. The point must use a 1 kΩ end-of-line (EOL) resistor.
– Install the 560 Ω, 2 W EOL resistor beyond the last notification device on each NAC loop.
This resistor is included with the module.
– For a supervised point, install a 1 kΩ EOL resistor across the COM and SUPV ZONE
terminals on the last D192G module.
