SCR25A Call-In Module, CA17 Call-In Switch

SCR25A Call-In Module

The SCR25A module can be added to allow the annunciator indicators to light from a simple SPST call-in switch (Bogen model CA17). All call-in switches must go back to the SI or PI on separate lines. It will not allow annun- ciator illumination from parallel connected call-in switches described in the Voice call-in section. The SBA225 module simply pushes onto the connectors on the back of the SBA225.

The figure below illustrates the connections to the rear of the SCR25A module.

Jumper Settings (see screened drawing on the SCR25A board).

1.Ensure that jumpers J1 - J25 are positioned to the left (toggle position) as shown.

2.Ensure jumper J26 is positioned towards the pin side (Multigraphic position) of the SCR25A module

CA17 Call-In Switch

The CA17 call-in switch is a SPST call-in switch. It must be used with the SCR25A module in order to light the call annunciators on the SBA225 room selector panel.

The wiring of the CA17 is shown in the drawing above.
