MINI-433
versa wireless
The MINI-433 is a 433 MHz door and window contact for DSC PowerSeries (1832 / 1864), Impassa, and Alexor systems. At 2.2" × 1" × 0.25" it's roughly half the depth of the DSC WS4945 factory contact, so it sits flush on aluminum profiles, narrow window channels, and tight casing where the OEM sensor won't.
The patented Bluefield magnet indicator lights a blue LED when the magnet is in range, so you confirm placement at the opening instead of walking back to the panel. The cover slides off by hand for tool-free battery and color service with the sensor still mounted.
