MINI-433
versa wireless
A clean, low-profile door/window contact built for the DSC world — PowerSeries, Iotega, and Impassa. At just 0.25" thick, the MINI-433 sits nearly flush against the frame and slips into spots where the bulkier DSC factory contact (WS4945) won't fit. The patented Bluefield magnet indicator confirms placement at the door, so you skip the trial-and-error trips back to the panel. Single zone, fully supervised, and engineered around the install workflow.
Key Features
- Patented Bluefield magnet indicator — blue LED lights when the magnet is within range; confirm placement before you commit the tape
- Ultra-low-profile design — 2.2" × 1" × 0.25" transmitter is roughly half the depth of the DSC WS4945; fits tight casing and narrow frames
- Diagnostic LED set — blue (magnet in range), green (transmit confirmation), red (low-battery alert flashes once every five seconds after a trip)
- 1" magnet gap on wood, 1/4" on metal — tolerant placement for real-world frames
- Tamper + reed switch — full supervision; tamper trips on cover removal
- 5+ year battery life on a single Panasonic CR2032 coin cell
- Slide-off cover — clean tool-free battery service
- 433 MHz — drops into DSC PowerSeries (NEO, 1832, 1864), Iotega, and Impassa installations
- UL listed · FCC · IC · 95% RH non-condensing · 32–122°F operating range
