The Teracom TSV101 is an industrial-grade AC voltage detector designed to monitor the presence or absence of utility, grid, or generator power. Operating across a wide alternating current voltage spectrum (90 to 250VAC), this specialised sensor provides standard automation hardware with an instantaneous digital line status.
Housed in a compact, durable enclosure, the TSV101 bridges high-voltage power networks and low-voltage digital telemetry systems safely. It provides continuous power tracking for data centres, remote telecom sites, server rooms, and commercial infrastructure.
The fundamental engineering feature of the TSV101 is its total galvanic isolation between the high-voltage AC mains input and the low-voltage DC monitoring output.
Because the output is a pure open-collector digital switch, the TSV101 does not require complex serial communication protocols. It wires directly into a standard Digital Input (DI) channel on any Teracom network controller, such as the TCG120-4, TCG140-4, or TCW modules.
When paired with a Teracom controller, a change in the TSV101’s switch state can automatically trigger several real-time localised or network actions:
While the TSV101 handles power failure threats, Teracom’s network controllers allow you to unify this digital data within a comprehensive environmental monitoring matrix. In data centres, commercial facilities, and unmanned telecom hubs, power failure can be covered by short-term battery back-up, other threats to operational continuity can require more urgent action. By integrating Teracom’s TCG or TCW controllers alongside various climate, water detection, and physical sensors, facilities managers can consolidate multi-vector risk tracking into a single, cohesive dashboard.
Whether monitoring a critical server facility or a remote infrastructure substation, this unified ecosystem ensures that overlapping threats, such as HVAC equipment failures, environmental spikes, flooding, power anomalies, or sudden pressure drops, are immediately detected and alarms raised.
The table below outlines how specific sensors integrate with Teracom controllers to safeguard your infrastructure across multiple threat vectors:
| Threat Vector | Monitoring Sensor | Controller Interface | Automated Logic Response |
|---|---|---|---|
| Water Detection | TSF400-0 Floor Probe | Digital Input (DI) | Closes localised supply valves via Relay; issues urgent SMS/Email alerts. |
| Ambient Climate Shift | TSM400-4-TH Wall Node | RS485 Modbus RTU Bus | Triggers HVAC fan over-rides or changes cooling-loop targets; tracks data-center thermal mapping profiles. |
| CO2 Gas & Barometric Pressure Changes | TSM400-4-CP Gas Node | RS485 Modbus RTU Bus | Forces dynamic fresh-air intake damper positioning; flags room-pressure breach alerts. |
| Main Power Failures | TSV101 AC Voltage Detector | 1-Wire Sensor | Flags blackout/UPS input drops instantly via galvanic isolation; switches cellular loggers to power-save mode. |
| Smoke & Fire Outbreaks | TSS8030R Smoke Detector | Digital Input (DI) (Latching Relay) | Locks output to alarm state; enables remote power interlock shutdowns and fires immediate high-priority alerts. |
| Pressure Changes | 4-20mA Pressure Transducers | Analogue Input (0-10V / 20mA) | Detects critical pressure drops in cooling lines or HVAC plenums; generates system alarms. |
