Emergency Alarms for Safety Stations and Laboratory Fixtures

Select an emergency alarm by how the station will be activated, who must be notified and the environment where the components will operate. Compare Guardian and Haws light-and-horn assemblies, flow switches and remote-sensing options for safety stations and laboratory emergency fixtures.

Choose the Signal and Activation Method

A horn provides an audible alert; steady, flashing or strobe lights add a visible signal. Combination light-and-horn models are useful where noise, distance or hearing protection can make a single signal less effective. Match the notification method to the facility response plan rather than selecting a light style by appearance.

Most systems use water flow to trigger the alarm. Confirm whether the assembly includes the flow switch or requires one separately, whether the switch is installed directly in the station piping or uses remote sensing, and whether a silencing switch is needed for testing and maintenance.

Match the Alarm to the Fixture and Location

Safety-station alarms and laboratory-unit alarms are not automatically interchangeable. Verify pipe size, switch arrangement, voltage and mounting location for the exact fixture. Recessed and surface-mounted laboratory units may use different alarm assemblies from freestanding safety stations.

For wet, washdown or corrosive locations, compare the specified enclosure rating. Hazardous-location models must match the area classification shown in the project specification; a standard weather-resistant alarm should not be substituted solely because it looks similar.

Confirm Before Ordering

  • Fixture model and pipe size
  • Horn, steady light, flashing light or strobe requirement
  • Local flow switch or remote-sensing arrangement
  • Voltage, enclosure and hazardous-location classification
  • Silencing, monitoring and building-alarm connections

For compatible fixtures, compare Safety Stations and Laboratory Units.
