Bosch Dual Phone Line Switcher, D928

All reporting fire alarm systems are required to have a primary and alternate means of transmitting reports to a receiver. The D928 Dual Phone Line Switcher allows the control panel to operate over and supervise two separate phone lines. Typical applications are schools, factories, and care facilities where the ability of the system to relay information off-premises is especially critical for safeguarding life and property.
