Overview
The M1RF receiver is wired to the M1 via the 4 Wire High-Speed Databus and receives signals for connecting radio detectors and radio keys to the Ness M1 cross-platform controller.
Placed upon the databus the M1RF Receiver may be located anywhere along the bus and does not need to be located next to the panel. This means that if required the receiver could be located up to 1 Km from the panel. Allowing more than 1 receiver to be connected to any system distances between detection devices to the receiver is not an issue.
The wireless zone alarms replace hard wired zones on the M1, where each radio key can either replace one of the 199 user codes or alternately can be programmed in as an addition to user codes 204-255. Each of the 4 buttons on the Ness Radio key can be programmed to work the same globally for each key, or each button can be programmed to work individually from each other.¹
