Power Failure SMS Alert Device
The Accumax Power Failure SMS Alert Device is a GSM-based short message and missed call notification system that reports power outage and restoration to up to five mobile numbers, replacing manual monitoring of equipment.
How it works
A GSM-based notification system monitors power status and, on a power outage or restoration, sends a short message and a missed call to the registered mobile numbers so the recipient can take prompt action. In the temperature-alert variant it also monitors temperature and signals rise and restore events against a cutoff setting. LED indicators give visual feedback while an alert message is being transmitted, and the device is configured and interrogated by SMS command.

7 further specification s are listed in the datasheet but not reproduced here
These labels appear in the datasheet, but the value beside them could not be read reliably from the document. Rather than print a figure we cannot stand behind, we have left them out — ask us and we will confirm them directly.
- Battery Standby Time — the row exists in both v5.0 manuals but its value reads only "hours" (number lost by the text layer)
- Storage Temperature — label present in all three PDFs, value blank in every one
- Operating Temperature — label present in all three PDFs, value blank in every one
- Humidity lower bound in the two manuals — the row reads "95% (non condensing)", the lower limit is missing
- Warranty month count in POWER_ALERT_MANUAL — that sentence is in an encoded subset font and the number did not survive
- LED Indicators figure/table in section 2.4 of both manuals is preceded by a heading with no accompanying image text
- SMS command example screenshots throughout both manuals (sections 3.1–4.4) — the "SMS Example" captions survive but the example content did not
Applications
- Intensive Care Unit (ICU) - safeguard critical medical equipment and ensure stable power supply, with immediate alerts for power fluctuations
- Food industry / cold storage - maintain optimal temperature conditions to preserve food quality, with temperature alerts to prevent spoilage
- Server rooms and data centres / IT infrastructure - ensure continuous power availability, with power on/off and temperature alerts to prevent equipment damage
- Aquarium - maintain a stable environment for aquatic life by monitoring power supply, with temperature alerts against fluctuations
- Automation industries - keep automated manufacturing and production systems running, with power and temperature alerts to prevent downtime and machinery damage
Frequently asked questions
How many people can be notified when the power fails?
Up to 5 mobile numbers receive the alerts.
How does the device notify me - SMS only?
It sends both an SMS and a missed call. LED indicators give instant visual feedback while the alert message is being transmitted.
Do I get an alert when power comes back, or only when it goes off?
Both. It is a notification system for power outage and restoration, and gives a Power On/Off alert so you stay informed about power status changes.
Does it monitor temperature as well as power?
It is offered in two versions. The version with temperature alert gives temperature rise and restore alerts to prevent overheating issues; the version without is for standard power monitoring with no temperature-specific notifications.
Can I change the settings without visiting the site?
Yes. Simple SMS commands let you access all parameters' data and modify the cutoff temperature setting or register mobile numbers.
Where is this device typically used?
Accumax lists intensive care units, food industry and cold storage, server rooms, aquariums and automation industries.
