2.4.4Master Controller Wiring For Dual Systems
If your installation is a Dual (Red/White) system, you must make additional connections to coordinate between the High Intensity Strobe System and the Red Light System.
See the sections below for wiring details. For configuration switch settings for a Dual system, see 2.2.1.3 on Page
2.4.4.1Controlling the Red Light System
The Master Controller uses Relay K4 to control the Red Light System. The Relay K4 contacts should be wired to the Red Light System in such a way that when K4 is energized, the Red Lights turn off, and when K4 is
on.
Typically this is done by disconnecting the Red Light System photocell, and wiring those photocell inputs to the Relay K4 contact. The contacts are rated for up to 5A, and up to either 30VDC or 250VAC.
If your red light system has a Honeywell

Configure the 9LCA Red Light Controller to use Automatic mode control. Other Red Light Systems may require different connections. Refer to the Tower Kit drawing (if Honeywell provided both systems as a kit), refer to the Red Light System's manual, or contact Honeywell for assistance.
