Smart Door Alarm
Intelligent cold storage door monitoring device (MY-DSAS01). Auto-alarms when a cold room door is left open — saves 2–5 kWh per day with an extremely short investment payback period.
Business Challenges
Cold room doors left open
Staff frequently enter and exit cold storage — doors are often left open, causing continuous energy loss.
Persistently high energy costs
Even a few minutes of an open cold room door wastes significant electricity — cumulative annual losses are substantial.
No real-time monitoring
No one watches the kitchen back-of-house in real time — doors left open for hours go unnoticed until too late.
Food safety risks
Cold chain temperature anomalies can lead to ingredient spoilage, creating food safety hazards.
MY-DSAS01 Smart Door Alarm
Mounted on the cold room door frame — automatically monitors door open/close status and triggers an audible and visual alarm after the configured time, prompting staff to close the door promptly.
0–999 minute configurable delay
Flexibly set alarm trigger time based on actual usage scenarios to avoid false alarms.
Instant audio & visual alarm
Dual sound and light alert fires immediately when the door stays open beyond the set time — ensuring staff respond immediately.
Low-power design
Extremely low standby power consumption with long battery life — suitable for all environments without power outlet access.
No-drill, easy installation
Magnetic / adhesive mounting — no door frame modification required. Fully deployed in 5 minutes.
Multi-door centralized management
Supports unified management of multiple devices across all store cold rooms and refrigerators.
History log and reporting
Records each door-open duration and alarm count — providing data for energy management and staff training.
