Apollo 55100-031APO Indoor Intrinsically Safe Manual Call Point (470 ohm)

Apollo 55100-031APO Indoor Intrinsically Safe Manual Call Point (470 ohm)

The Conventional IS Manual Call Point has been designed to operate on conventional intrinsically safe fire detection systems. 

Designed specifically for use in atmospheres in which explosive mixtures are or may be present, certain design considerations must be observed. Full information on this to be found in PP1095. 

The Manual Call Point is available in two versions, indoor and outdoor in either red or yellow. 

The Manual Call Point has an easily resettable element rather than a break glass. This call point is supplied with a backbox for surface mounting.

 It also features a unique ‘Plug and Play’ installation concept designed specifically to reduce installation time. The call point utilises a terminal block, where all installation cabling is terminated. 

The red Manual Call Point is approved to EN54-11 standard and complies with the requirements of the ATEX directive. 

Mechanical Construction 

The component parts of the call point are moulded in polycarbonate or ABS, depending on their function.

Operation

The Manual Call Point consists of a 470 resistor in series with a normally open switch contact. 

The Manual Call Point helps reduce installation time as all the initial installation cabling is wired to a terminal block which connects neatly to the call point. 

Once activated, the 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.
