Installation and Programming Instructions for the Serial Interface Module

Serial Interface Module

With the SS2000 controller, if FRONT CUT OFF is preferred in MODE 1, set the active state for ENABLE.
(Apply 12 Vdc to activate the light heads.) The lead wire for FRONT CUT OFF is then connected directly to
the MODE 2 lead wire.
The active state for CUT OFF is programmable. The factory setting for FRONT and REAR CUT OFF is to
activate when 12 Vdc is applied; FRONT and REAR CUTOFF must share the same active state.
FRONT and REAR CUT OFF can be programmed to activate when 12 Vdc is removed from the respective
control leads. To change the active states for FRONT and REAR CUT OFF, remove ignition power to the
Serial Interface Module. Refer to Table 1 on page 3 for the DIP switch settings.
Programming the Intersection Function
The INTERSECTION function can be programmed to be activated for HIGH (+ BAT maintained), or
TAP II (+BAT, push on/push off), or 8-SECOND TIMEOUT (activated by +BAT). The factory setting for
INTERSECTION is HIGH (+BAT maintained).
To change the active state for the INTERSECTION Mode, remove ignition power to the interface module.
Refer to Table 2 for the DIP switch settings on SW2. OFF is the up position and ON is the down position.

Selecting External SignalMaster Control
The Serial Interface Module is factory-configured for INTERNAL control. (See the next section.) When the
Serial Interface Module is configured for EXTERNAL SignalMaster control, an external Federal Signal
SignalMaster controller or an SS2000SM Series siren can be used to control the SignalMaster in all
Convergence Network controlled light bars.
For the 36-inch Arjent S2, a four-head external SignalMaster is required. For the 44-inch Arjent S2, external
SignalMaster controllers must be six-head. For 53-inch and longer models and the Valor and Vision SLR
models, an eight-head SignalMaster controller is required.
To select external SignalMaster control, remove ignition power and return SW2 Switch 4 to the OFF (up)
position. To wire the SignalMaster for external control, see page 9.
Selecting Internal SignalMaster Control (Factory Default)
Internal control uses the on-board SignalMaster controller in the light bar to generate directional warning
patterns. With internal operation, an external SignalMaster controller is not needed. A standard low-current
switch box can activate the internal SignalMaster controller. To wire the SignalMaster for internal control, see
page 9.
To select internal SignalMaster control:
1.
Remove ignition power to the Serial Interface Module.
2.
Move SW2 Switch 4 to the ON (down) position. See Table 1 on page 3.
