How to choose a technical alarm system for a poultry farm

A modern poultry farm depends on ventilation as much as it does on feed. A 30-minute exhaust failure during a heat wave can cost an entire flock, and the worst time to find out is at 8:00 AM when the morning operator arrives. A well-sized technical alarm is what separates "complete flock" from "quantified incident".

This guide covers what to require before signing a technical-alarm contract for a poultry operation — meat, layers or breeders.

1. What it really has to monitor

The four variables that lose a poultry farm the most flocks, in damage order:

Ventilation down (fans stopped or at minimum speed during a heat wave): heat-stress mortality in 60-90 minutes.
General power outage with no generator running: drags everything else with it.
Over-temperature from a faulty probe or cooling issue: thermal damage before the morning round catches it.
Excess NH₃ or CO₂: welfare and feed-conversion loss, not deadly but it eats productivity.

The right combination for poultry: per-room temperature, humidity, CO₂, pressure drop (in tunnel systems) and the electrical panel contacts on the ventilation board. Aviot's hardware integrates all of this in a single board.

2. Probe-based detection alone is not enough

An alarm that only fires on temperature is late. By the time the probe reads +1 °C above setpoint, you already have minutes of trouble. Electrical detection — reading the differential contact, the phase or the fan contactor — gives you the alarm at the moment the cause breaks, not when the effect shows up.

Demand from the vendor that the board can read at least 8-32 voltage-free digital inputs, so you can wire the auxiliary contacts on the panel and monitor differentials, phase loss and generator start.

3. Multi-channel alerting with human acknowledgment

A 3 AM email wakes nobody. An alarm is useful when it calls by phone and demands human acknowledgment (press 1, say your name, anything) before moving on to the next contact. If nobody picks up, it escalates automatically.

Features that must be there:

Automatic voice call (not just SMS).
Priority-ordered contact list.
Re-call and escalation after N seconds without response.
SMS and push as parallel channels, not the only one.
History of who answered and when.

4. Independent connectivity, not the office router

Most common mistake: hooking the technical alarm to the office Wi-Fi. When the power goes out, the router goes too, and the alarm goes silent at the worst possible time.

Minimum viable: 4G IoT connectivity with its own SIM and an internal lithium battery good for several hours without grid. Multi-operator with automatic failover is even better — rural coverage is uneven and betting on a single operator is assuming risk.

5. Exportable history for audits

Integrators and certifiers (animal welfare, IFS, poultry integration) will request incident history. If your technical alarm doesn't export to CSV/Excel and doesn't store timestamped readings, audits become a nightmare.

Concrete question for the vendor: how long do you keep readings and events? Can I download them without paying extra? Aviot keeps the full history and lets you export it at any time.

6. Professional installation, not DIY

A board wired into the electrical panel isn't a weekend project. Demand from the vendor a qualified technician with electrical certification and properly insulated voltage-free connections. A bad install can inject electrical noise into the panel and cause spurious tripping.

Reasonable install time for a medium farm: 3-4 hours. If they say 30 minutes, doubt it. If they ask for 2 days, also doubt it.

7. Warranty and support after month one

Everyone is attentive in the first month. The difference shows in month six, when a probe gives a false alarm at 4 AM and you need a human on the other end. Ask:

Is technical support 24/7 or only business hours?
Does the warranty cover hardware replacement within how many days?
Is there a fee for configuration changes (thresholds, contacts)?
Is the IoT SIM included or billed separately by usage?

Summary: pre-signature checklist

✅ Per-room temperature, humidity, CO₂ and pressure drop.
✅ At least 32 digital inputs for panel contacts.
✅ Voice call with acknowledgment, escalation, SMS and push.
✅ 4G multi-operator IoT + Wi-Fi backup + internal battery.
✅ Exportable history (CSV/Excel).
✅ Professional installation in 3-4 h.
✅ 3-year hardware warranty + 24/7 support.
