Alarmed Sequential Switcher
The Nortek series of six low voltage sequential switchers utilises flush membrane style switches giving positive tactile feedback and visual camera identification via LED indicators.
Independent sequencing of each camera is variable from 1 to 250 seconds with manual override controlled by tactile switches.
Unused camera inputs can be skipped and for additional security disconnected inputs will display a blank screen unless they are programmed out.
With a choice (on installation) of normally open or normally closed alarm contacts auto sequencing is overriden when an alarm is triggered thereby automatically switching to the camera in the alarmed state. The alarmed camera will be overridden should a second alarm be triggered and will run for a selectable period of between 1 and 250 seconds nominal.
A second wiring option is available to the installer whereby the switcher will only revert to auto sequence mode once the alarm has been manually reset. A voltage free contact relay is provided for triggering a VCR or external alarm. The audible alarm may be silenced.
A spot monitor function is provided on the VS88 and VS88A with independent sequence for each camera.
