4.4.2 Configuring the Quad Channel Input Module
The Quad Channel Input Module has switches for Detector Type, Selection and Module
Selection, and a link LK11. See Figure 6
Figure 6: Switches on Quad Channel Input Module
If the system is supplied with Crowcon detectors, the Quad Channel Input Modules are
already configured. If the system needs configuring, follow the instructions below.
Table 8: Quad Channel Input Module switch settings
Letters refer to labels in Figure 6.
LK 11
If the first channel of a module is a fire
detector connected to the Vortex system via a
Zener Barrier, then make the link LK11. In
all other cases, including when the fire
detectors are connected directly to the panel,
leave this link unmade.
Module Selection
Switch (F)
Determines the channel number for the
module. The physical order of the modules
on the Bus Rail is not important.
Position 0 - This module has channels 1-4
Position 1 - This module has channels 5-8 if
two or three modules are used
Position 2 - This module has channels 9-12 if
three modules are used
