System Setup

Number of zones

Smoke detectors

Heat detectors

Manual pull stations

Sounders / strobes

Inject a supervisory fault, then practice diagnosing the panel's trouble signal.

Open circuit (IDC)

Choose the audible notification pattern, then trigger an alarm to hear it — or play a voice-evacuation demo.

Notification pattern

Uses your browser's built-in speech — no audio files. Voice-evac (ECS) systems announce spoken instructions during an alarm.

1Set your zones and device counts to match your design.
2Tap an initiating device (smoke, heat, or pull station) to activate it.
3Watch the panel go into ALARM and the strobes/sounders respond.
4Use Silence to quiet the alarm, then Reset to return to normal.
5Inject a fault (open circuit or low battery) to practice reading trouble signals.

Smoke Detector: Detects products of combustion and triggers an alarm on the initiating circuit.
Heat Detector: Responds to a fixed temperature or rapid rise and initiates an alarm.
Manual Pull Station: Confirms a person can manually initiate an alarm from a pull station.
Sounder / Strobe: Confirms notification appliances produce the evacuation signal (audible + visible).
