Technical Datasheet
MINI-433 Door/Window Sensor
The Versa Wireless MINI-433 is a compact 433 MHz wireless door and window contact for DSC PowerSeries PC1832 and PC1864, DSC Impassa, and DSC Alexor systems.
It measures 2.2" × 1" × 0.25" (55.9 mm × 25.4 mm × 6.4 mm), runs 5+ years on a single Panasonic CR2032, and uses patented Bluefield magnet alignment to confirm placement at the opening. Full specifications are below, with a printable PDF for download.

Key features
Bluefield magnet alignment
Patented Bluefield technology confirms the magnet and transmitter are aligned and working, so you verify placement at the opening.
5+ year battery life
A single Panasonic CR2032 coin cell typically lasts 5+ years, so replacements are far and few between.
Easy-open slide lid
The slide-off lid makes battery replacement and color changes quick and easy, with no need to remove the electronics from the plastics.
- Patented Bluefield magnet alignment — blue LED confirms the magnet is within range during install
- 5+ year battery life on a single Panasonic CR2032
- Easy-open slide lid for tool-free battery and color-cover service
- Pre-installed adhesive tape for fast surface mounting
- Battery pull-tab to activate the transmitter
- High-power neodymium magnet for a gap over 1.0" (25.4 mm)

Frequently asked questions
What panels is the MINI-433 compatible with?
The MINI-433 is a 433 MHz contact for DSC systems: DSC PowerSeries PC1832 and PC1864 with a 433 MHz receiver (such as the RF5132-433), DSC Impassa, and DSC Alexor. It enrolls as a standard supervised door/window zone.
What frequency does the MINI-433 use?
The MINI-433 transmits at 433 MHz, the frequency used by DSC PowerSeries PC1832/PC1864, Impassa, and Alexor wireless systems.
What are the MINI-433 dimensions?
The transmitter measures 1.0" (25.4 mm) x 2.2" (55.9 mm) x 0.25" (6.4 mm), making it a compact contact for narrow window channels and tight frames.
What battery does the MINI-433 use and how long does it last?
It runs on a single Panasonic CR2032 coin cell with a typical battery life of 5+ years. The slide-off lid lets you replace the battery without removing the sensor from the mounting surface.
What is the MINI-433 magnet gap?
The high-power neodymium rare-earth magnet delivers a gap of more than 1.0" (25.4 mm), giving flexible placement on doors and windows.
Is the MINI-433 UL listed?
Yes. The MINI-433 carries UL639 / 1023 and ULC-S304/C1023 regulatory listings.
What is Bluefield magnet alignment?
Bluefield is Versa Wireless's patented alignment technology. It shows the installer that the magnet and transmitter are clearly aligned and working, confirming placement at the opening instead of at the panel.
