Water Leak Alarm Options

The water detector alarm features vary by model. For example, the Model SS provides an audible alarm when activated and should be used in applications where only a local audible alarm is desired. The Model SS-1 provides local and remote water detection alarms when activated and is used in applications requiring a single detector and remote alarm which is perfect for noisy or unattended areas. The model SS-4 has no audible water detection alarm and provides isolated dry relay contacts (DPDT) which transfer and hold when activated.
