How to Connect Control Panels, Detectors, and Peripherals
A System Overview
This system overview shows how panels, detectors, and peripheral devices from Cerberus™ PRO can be connected:
The C-WEB/SAFEDLINK connects up to 16 networkable control panels and fire terminals.
The distance between two panels can be up to 3300 ft. The distance can be extended with a repeater or optical interface module.
All detectors are placed on the C-NET, a multipurpose detector bus system that is connected to a networkable control panel.
The detectors also communicate and get their power supply directly via the C-NET – without needing additional cabling.
The RS485 loop is connected to the serial interface of the RS485 class A module.
Devices that can be connected via the RS485 loop: remote display, remote terminal, and remote peripheral module.
The class A circuit can have a maximum length of 1650 ft.
The class B circuit can have a maximum length of 3300 ft.
A maximum of 8 devices can be connected.
Notification Appliance Circuit
The NAC circuit (Notification Appliance Circuit) is a supervised circuit for connecting horns, strobes, loudspeakers, sprinkler valves etc.
The connected devices also receive their power supply via the NAC circuit.
One class A or two class B circuits can be realized.
The NAC circuit can be extended using an additional NAC module.
The C-NET and the C-WEB/SAFEDLINK are implemented as a loop.
This increases fire safety: In case a bus has been interrupted at one point or a short circuit has occurred, a message is simply redirected the other way.
