SLU-16
The SLU-16 Remote Annunciator Lamp module has 16 LEDs
for remote annunciator applications when using the SAN-CPU.
The system software individually controls all LEDs and
switches. When a pre-defined input exists on the system, the
appropriate LED will illuminate to report the condition.

SWU-8
The SWU-8 consists of 8 two-position toggle switches and 16
red or yellow LEDs. Each switch forms a distinct functional
group with two independently programmed LEDs. Placing a
switch in the up position generates an active (off normal)
condition. The down position is the normal state.
In a typical firefighter telephone application using the SWU-8,
the upper switch position selects an incoming call; the lower
switch position places the circuit to normal or off-line operation.
One of the associated LEDs indicates the circuit calling in; the
other LED indicates that the circuit has been connected to the
master handset.
