Connection Details
All Customer connections are available on the rear of the Motherboard mounted on the back of the
annunciator as shown on the figure below.
Each system will consist of a single SPR Card (supply, pushbuttons and relays) and multiple four-
channel alarm cards.
The SPR card is always situated on the far left, when viewed from the rear, and provides all the
common connections for both inputs and outputs.
The number of four channel alarm cards fitted will depend on the system size but these all have
exactly the same connections for the four alarm contact inputs and four volt-free relay outputs.
At the top of each alarm card there is a label referring to the channel numbers for that card, these
channels refer to the numbering scheme for all the inputs as shown above.
All terminals are of the rising clamp type and are suitable for cable of up to 2.5mm2
