DMP 1112 Wireless Water and Temperature Detector
The DMP 1112 is a wireless water and temperature detection sensor designed for facilities where water intrusion or thermal drift pose operational or safety risk. It detects water presence within one minute of contact and monitors temperature thresholds (below 45°F or above 95°F for more than ten minutes), then transmits alerts to a compatible DMP control panel or monitoring platform. The wireless architecture eliminates conduit runs and junction boxes—install it in basements, mechanical rooms, data centers, or any temperature-sensitive space without running cable. Low-profile form factor and battery-powered operation make it ideal for retrofit deployments where wired sensor infrastructure isn't feasible.
Key Features
- Dual Water and Temperature Sensing: Detects water contact within 60 seconds and monitors temperature drift (thresholds: below 45°F or above 95°F for sustained 10+ minutes). One sensor covers two failure modes in critical infrastructure.
- Wireless DMP Protocol: No conduit, no junction boxes, no power runs. Retrofit-compatible installation into existing DMP wireless receiver modules and control panels.
- Battery Powered (3V DC): Ships with two CR2450 coin cell batteries. No external power supply required; estimated battery life supports multi-year operation depending on alert frequency and environmental conditions.
- Compact Form Factor: 1.25 x 1.25 x 1.0 inch sensor weighs 0.03 lbs. Unobtrusive placement on floors near water sources or walls in temperature-critical zones.
- Multi-Zone Capable: Programmable with up to three zones, allowing a single unit to monitor multiple locations or conditions if the receiver supports multi-zone assignment.
- Immediate Alert Transmission: Water detection and temperature threshold breaches trigger instant wireless alerts to paired control panel or monitoring platform for rapid response.
Water and temperature sensors are critical infrastructure sentries in data centers, server rooms, and mechanical spaces where a single failure event—burst pipe, HVAC malfunction, or cooling system drift—can cascade into equipment loss and operational downtime. The 1112 eliminates the installation and maintenance burden of wired sensor networks by operating wirelessly on battery power. In retrofit environments where running new conduit would require ceiling demolition or floor penetration, wireless deployment reduces project cost and timeline significantly.
Integration with DMP facility monitoring and access control systems ensures alerts route to the same platform that manages door locks, motion detection, and other security and lifecycle sensors. This consolidation simplifies operator training, reduces alert fatigue from fragmented platforms, and accelerates incident response because maintenance and security teams see a unified incident timeline. DMP control panels configured with wireless protocol support accept the 1112 sensor type without firmware updates or external gateways; the receiver module handles pairing and threshold configuration via standard commissioning procedures.
Placement strategy directly affects detection reliability. Position water sensors on floors in basements, under raised floors, near HVAC condensate lines, and at floor drains where pooling occurs first. Temperature sensors work best mounted at mid-height on walls in mechanical rooms or mounted inside cable trays in data centers—avoid direct sunlight and heat-source proximity that would skew readings. The device is non-invasive and requires no special tools; a maintenance technician can place and commission a unit in under five minutes once the receiver is ready to accept input.
The DMP 1112 carries a manufacturer warranty and operates under DMP wireless architecture standards. Current inventory includes firmware version 201 (July 15, 2025), which corrects low-battery reporting thresholds to prevent premature false alerts. If deploying in environments with complex multi-zone requirements or mixed wireless/wired sensor networks, verify your control panel model supports the 1112 sensor configuration before purchase.

We've deployed the DMP 1112 across data centers, server rooms, and mechanical spaces where water intrusion and thermal monitoring are non-negotiable. The real operational win here is retrofit simplicity—most facilities we service have aging conduit infrastructure that's already saturated or routed through architectural elements (concrete floors, finished ceilings) that make adding new sensor wire prohibitively expensive. The 1112's wireless-first design sidesteps that entirely. You place the sensor, pair it once, and it operates autonomously on batteries for years. The dual-sensing stack (water + temperature) is deliberately designed to catch two of the most common data-center failure modes: coolant leaks and HVAC setpoint drift. In practice, we've seen the 45°F low-temperature threshold catch compressor failures and water-line freeze-ups in unheated backup areas before they propagate. The 95°F upper threshold is tunable via the control panel, which is critical for warm-aisle containment scenarios where your ambient air temperature legitimately hovers near 85°F—you don't want nuisance alerts.
Technical Highlights:
- Water Detection Response: 60-second water contact detection means you catch pooling within the first minute of a breach—early enough to trigger automated shutdown logic or alert response before significant infiltration. We've seen this win countless times on condensate-line ruptures in data centers.
- Temperature Thresholds (45°F / 95°F, 10+ minute hold): The 10-minute sustained threshold eliminates transient spikes from HVAC cycling or opening bay doors. You're not chasing phantom temperature alerts; you're catching real thermal drift. In our experience, this threshold tuning is the difference between useful and noisy.
- Battery Life Estimation: Two CR2450 coin cells typically sustain 2–4 years of operation depending on alert frequency. In quiet environments (low water risk, stable temperature), we've seen installations push 5+ years. Plan battery replacement into your PM schedule at year 3 to avoid surprise service calls.
- Wireless Protocol (DMP Native): No third-party gateways or protocol translators. The sensor speaks native DMP over whatever frequency your wireless receiver module operates. This keeps integration path simple and avoids RF architecture fragmentation.
- Compact Sensor Footprint: 1.25-inch form factor is genuinely unobtrusive. You can mount it under raised floor tile, inside a cable tray, or on a wall without drawing aesthetic complaints from facilities teams—critical for retrofit projects in occupied data centers.
Deployment Considerations:
- Receiver pairing must happen before you deploy the sensor. The control panel needs to be in commissioning mode and programmed to accept a new water/temperature sensor. If your panel firmware predates the 1112 support window, confirm with DMP before ordering—older panels may not recognize the sensor type.
- Water sensor placement is critical: position it on the floor (not elevated) in low points where pooling occurs first. Condensate lines, HVAC drain sumps, and floor drains are the right spots. Mounting it vertically on a wall will miss slow leaks that run along the floor.
- Temperature sensor accuracy degrades near heat sources or direct sunlight. Mount wall sensors at mid-height in mechanical rooms, away from equipment exhausts and windows. In data centers with aisle containment, mount within the warm aisle to detect recirculation failures.
- RF propagation in data centers with dense metal racking can be unpredictable. If you're deploying multiple sensors across a large floor plan, do a quick RF walk-test with a receiver to confirm signal strength before committing placement. Steel cable trays and metal frame buildings can create dead zones.
- Firmware version 201 (current as of July 2025) resolves low-battery reporting edge cases. If you have inventory older than mid-2025, reach out to DMP support—early units had occasional false low-battery alerts that this version fixes.
The 1112 is the right choice for retrofit-sensitive facilities (occupied data centers, hospitals, active server rooms) where running new sensor conduit is prohibitive and DMP infrastructure is already in place. It's also ideal for temporary or seasonal water-risk scenarios—equipment moves, roof work, or plumbing repairs—where you need rapid-deployment sensing without permanent infrastructure. If your facility already runs DMP wireless receivers and you're building out facility monitoring, the 1112 fills a real gap in the product line.
