Wireless dry contact sensors
Get real-time alerts about the status of essential equipment
Our wireless dry contact sensors monitor the status of any equipment that has a volt-free, dry contact output, such as UPS status, security systems, fire alarms or air conditioning units. The small, energy harvesting devices use ultra-low power wireless and battery-less technology, making them easy to install and very low maintenance.
Get accurate, reliable status updates
The sensor simply connects using a push-wire and sends instant open/close updates if the contact status changes.
Solar-powered with battery back-up for easy install
The sensors use ambient room light – natural or lighting – with a battery back-up, making them super easy to install and very low maintenance.
Access real-time data locally or in the cloud
Temperature data can be sent securely to a local network or the cloud — via Ethernet, LTE (4G) or WiFi — using Pressac’s smart gateway.
- Reports dry contact status changes in real-time and status
updates every 15 minutes
- Small, discreet sensors simply stick to a wall or side of the equipment
- Connect to the device using a push-wire connection of two wires
- Solar-powered using ambient room light – optimally angled to absorb light – with a battery back-up for periodic low-light conditions. Batteries typically last up to 10 years
- Transmit data wirelessly and securely – using AES-128 encryption – via EnOcean wireless protocol, which uses internationally approved, licence-free ISM bands
- 868 MHz for Europe (RED)
- 902 MHz for North America (FCC) and Canada (IC)
- 928 MHz for Japan (ARIB specification)
- EnOcean Equipment Profile (EEP): D5-00-01
- No recurring fees. Access the data through your chosen platform, without any additional costs from Pressac
- Manufactured in the UK to high-quality and high-safety specifications, they are subject to rigorous testing procedures
- Dimensions: 76.5 x 28 x 17.5 mm (approx)
