Figure 4. Wiring Diagram for the 105DHIST-FJ Series

NOTE: DC polarity of circuit shown in supervisory state (signal inactive). Circuit polarity to reverse to activate signal.
Electrical supervision requires wire run to be broken at each device.
Device for constant input voltage. Do not connect to “coded” or pulsating voltage.

*Use the operating current to establish the wire gauge and standby power requirements. Consult the control unit manufacturer to
determine surge and peak current effects and maximum number of strobes on the system.
**CAUTION: To prevent damage to the visual signal's internal circuit and to assure its continued proper functioning, DO
NOT operate the unit outside of the Special Application voltage range of 20-30V DC.
