The Discovery Marine Manual Call Points has been designed for use in marine and offshore environments and are available in two versions for indoor and outdoor applications. Both versions are available with and without short circuit isolators. An alarm is initiated by pressing the resettable element. The Manual Call Point signals to the Control and Indicating Equipment using an interrupt feature within the Apollo Digital Protocol. An alarm status is indicated by a yellow and black bar in the lower section of the resettable element and a red LED. The Manual Call Point can be easily reset from the front using the supplied reset key.
