Product Information
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.

Electrical Description
The Discovery Marine Manual Call Point is loop powered and operates at 17-28V DC for all variants.
Operation
The address of each call point is set at the commissioning stage by means of a seven-segment DIL switch. On the indoor versions, the address switch is accessible without removing the call point from the mounting surface.
A red alarm LED is provided on the call point.
This LED is controlled independently of the call point, by the control panel.
This Manual Call Point helps reduce installation time as all the initial installation cabling is wired to a terminal block which fits neatly in the back of the call point.
Once activated, the Discovery Marine Manual Call Point can be reset by inserting the reset key into the front facing LED, turning clock wise, until a positive click and reset occurs.
Mechanical Construction
The component parts of the call point are moulded in a robust fire-retardant polycarbonate.
