Two-Stage Alarm Signs >
All of the signs in this category are worded for fire alarms with two-stage fire alarm systems. The first stage signal is an ALERT and the second stage signal is an EVACUATION ALARM. Note: this does not mean, however, that you will always hear the ALERT signal before you hear the EVACAUTION ALARM.
The ALERT signal is an intermittent signal or tone where you prepare to exit the bldg.
There are two types of EVACUATION ALARM signals:
The CONTINUOUS EVACUATION ALARM. This is a constant ringing sound usually generated by alarm bells.
The TEMPORAL EVACUATION ALARM. This is usually a tone generated signal (frequently beeps or whoops) with a pattern of 3 beeps, pause, 3 beeps, pause, (repeated).
To choose the correct sign for your location use the following method:
1) Choose the type of Evacuation Alarm, Continuous or Temporal
2) Choose if you have Elevators or No Elevators within the building or your occupancy space, and
3) Choose the "CAUTION" explanation.
Use the extended caution if your building is equipped to allow occupants protection from smoke filled corridors. e.g. apartment buildings, higher office buildings
Use the minimized alternate exit caution when it is safer for occupants to leave the building for their best protection. eg. restaurants, shopping centres, small office buildings.
