Electrical Considerations
The Discovery Waterproof Manual Call Point is loop powered and operates at 17-28V DC.
Operating Principles
The address of each call point is set at the commissioning stage by means of a seven-segment DIL switch.
A single bi-coloured alarm LED is provided on the call point. This LED is controlled independently of the call point, by the control panel. The LED is illuminated red when the call point has been activated.
The LED is illuminated amber/yellow LED to indicate a short circuit.
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 Waterproof Manual Call Point can be reset by inserting the test key into the bottom of the unit until the key clicks into position.
Remove the test key and push the front cover up until it clicks home.
The isolated version of the Discovery Waterproof Manual Call Point incorporates a short circuit isolator which will ensure its operation in the event of a short circuit fault on the loop. Full details of the isolator can be found in the PIN Sheet PP2090, available on request.
Mechanical Construction
The component parts of the call points are moulded in polycarbonate or ABS, depending on their function.
Backward Compatibility
The Discovery Waterproof Manual Call Point will operate only with control equipment using the Apollo Discovery digital protocol.
