Product Overview

The GSM Emergency Call Alarm System is a professional-grade wireless notification device designed for reliable SOS alert transmission via cellular networks.
When triggered by panic buttons or connected sensors, the system automatically sends SMS notifications and voice calls to predefined contacts. Operating via GSM networks, it functions independently of WiFi or landline internet, ensuring continuous operation in remote, industrial, or network-unreliable environments.

Core Advantages

Total Network Independence
Operates strictly via GSM mobile networks, entirely free from WiFi, routers, or landline dependencies. This ensures uninterrupted alert transmission during broadband outages and in remote infrastructure sites.

Triple Redundant Alerting
Eliminates missed alarms through instantaneous, multi-channel emergency broadcasting:

SMS Alerts: Simultaneous text notifications to preset numbers.
Voice Calls: Sequential automated dialing for immediate human confirmation.
Local Output: Direct power activation for connected external sirens or strobe lights.

Power Fail Protection
Equipped with an internal rechargeable Lithium battery that triggers an automatic switchover during local power outages or intentional wire-cutting, maintaining 24/7 continuous monitoring.

Engineering Integration & Scalability
Designed for fast deployment and low long-term maintenance in both legacy retrofits and new security projects:

Supports standard NO/NC dry contacts for wired/wireless sensors.
Universally compatible with third-party commercial alarm panels.
Scalable architecture optimized for multi-site enterprise deployments.

FAQ

Q: Does this system require a local internet connection?

A: No. It operates entirely over the GSM mobile network using a standard SIM card. It does not require WiFi, routers, or landlines.

Q: How many emergency numbers can be saved?

A: The system supports multiple predefined phone numbers. It dials the numbers sequentially and sends SMS alerts until the notification cycle is complete or acknowledged.

Q: How does the system handle power cuts?

A: If the external DC 12V power fails, the internal backup battery immediately takes over. The system can be configured to send an automated SMS notification alerting management to the power loss.

Q: Can it be installed outdoors?

A: The standard enclosure is rated for indoor or sheltered use. For harsh outdoor environments, we can provide specialized weatherproof enclosures (IP65/IP66) through our ODM services.

Q: Can it connect to existing third-party alarm panels?

A: Yes. Using the standard wired alarm inputs and onboard relay outputs, the device interfaces with most standard fire panels, security systems, and access control hardware.
