DCB, DCFCB and DCFCTB Models
Model 2001HR (Holding Relay)
This option enables the control of both of the siren motors from a single contact
closure on one-way models. This feature is typically required for telephone line
control systems and is only required if an FC is not purchased. The 2001HR is a
holding relay, which holds the rotator motor on for 15 seconds after the control
contact is released, keeping siren rotation active during Wail signals. The control
contact is wired between K2-C1 and ground.
Solar Power
When purchased, the solar option allows the siren to operate in areas where DC
power is not available. Our PVS2110-48 and PVS220W-48 models for the DCFCB
and DCFCTB controllers include a solar regulator and the solar panel kit. When
installed, the batteries are charged by the photovoltaic charging system, in lieu of a
battery charger, to provide operational power to the siren. Refer to Figure 22
DCFCTB Solar Wiring on page 83 and Figure 23 DCB and DCFCB Solar Wiring on
page 84.
