The dry contact (voltage free contact) is the universal alarm interface: nearly every piece of facility equipment offers one. The IND-IO monitors the state of any dry contact output enabled device across 16 distinct inputs:

• Generators: run, fail, low fuel and not-in-auto contacts.
• Fire & alarm panels: the common alarm and fault relays.
• UPS systems: on-battery, low-battery and fault dry contacts — even on units with no network card.
• HVAC & CRAC units: alarm and status outputs.
• Valves, relays & conventional detectors: anything that opens or closes a contact.

Sixteen inputs on one probe means one deployment covers the whole equipment room — every relay output in the space becomes a monitored, alerting point on the platform.

On top of the 16 inputs, the probe features 4 dry contact outputs to control equipment — turning the platform from a watcher into an actor:

• Start the backup air conditioning unit when the primary fails or the temperature climbs.
• Initiate a pump in response to a detected water leak.
• Drive relays, valves and fans — any equipment with a contact-closure control input.
• Switch remotely: outputs are controlled through the base unit, so the action can come from an operator or from your integrated systems.

Sixteen inputs from sixteen different devices need sixteen different rules — and get them:

• Normal open or normal closed, per port: each input is individually configured to match the wiring convention of the equipment behind it — NO and NC devices coexist on one probe.
• Minimum state duration: define how long a state must persist before it counts as an alarm. A contact that flickers for a moment during a generator start isn't a callout; a contact that stays open is.
• Polling down to 1 second: state changes are caught quickly enough for alarm-grade response.

Conventional contact-output detectors need supply power, which usually means a separate power brick and another socket. The IND-IO removes that step:

• 12 VDC power output, max 700mA, to power the attached devices — for example smoke, motion and door sensors.
• One cable run does it all: the probe itself is powered by the base unit over RJ45, and passes power onward to its detector loop.
• Cleaner installs: no wall adapters in the equipment room, no separate supply to fail unnoticed.

The dry contact predates every protocol on your network — and it will outlive most of them, because it's simple, reliable and universal. What it lacks is reach: a relay closing in a generator room tells nobody anything unless something is watching it.

The IND-IO is that something. Each input's state is published through the base unit as:

• Modbus TCP, BACnet IP & Modbus RTU registers for the BMS and EPMS.
• SNMP values and traps for the NMS and DCIM.
• MQTT topics for IIoT platforms (BASE-6 generation).

The result: 1980s equipment reporting into 2020s systems, without touching the equipment itself.

The probe belongs wherever contact-output equipment concentrates:

• Generator rooms: a single probe picks up run, fail, fuel and transfer switch contacts.
• Electrical & mechanical rooms: breaker status, pump status, HVAC alarms.
• Fire panel locations: mirroring the panel's alarm and fault relays into the monitoring platform.
• Legacy sites: anywhere an installed base of conventional detectors should join the platform without being replaced.

The probe plugs into the base unit over a single RJ45 cable carrying data and power, and reports the state of all 16 inputs.

• Standalone alerting: the base unit fires email, SNMP traps and optional SMS on any configured state change — no PC or software required.
• BMS integration: states published over Modbus TCP, BACnet IP and Modbus RTU — availability depends on the base unit model.
• NMS & DCIM integration: SNMP, including traps.
• Industrial IoT: MQTT, on the BASE-6 generation base unit.
