Someone always picks up

An alarm that nobody hears is not an alarm. Wyenfos calls, messages and notifies the first person on the chain, waits the time you set, then moves to the next, until someone acknowledges and records what they did.

Capabilities

Escalation that matches how your shifts work

Voice calls

Automated calls that read out the unit, reading and limit, and accept a keypress to acknowledge.

WhatsApp and SMS

Messages with the reading and a link to acknowledge and log the action.

Chains per unit

The vaccine store, the blast freezer and the trucks can each have their own people and wait times.

Shift rosters

Day, night, weekend and holiday rosters so the right person is first in line.

Alarm delays

A short delay per unit avoids alerts for a door held open during a restock.

Closed with an action

An alert closes only when someone records what they did, feeding the compliance log.

Common questions

What if the supervisor's phone is on silent?

Voice calls repeat, WhatsApp and SMS go out together, and the chain moves on after the wait time you set.

Can we have different chains for day and night?

Yes. Rosters change who is first in line by shift, weekend and holiday.

Are call and message charges included?

Plans include a monthly allowance of calls and messages per sensor; heavy usage is billed at cost.
