GENERAL:
Wheelock's Dry Contact Interface (DCI-24-24) is a handy interface for powering telephone bells, chimes, horns, strobes and other
extension alerts for electronic key systems. The wall-mountable unit is a quick and convenient way to provide power for up to 5
signals. This capability can be doubled by simply using one DCI to actuate another.
The unit is attractively packaged for wall mounting and comes with a six foot power cord to reach a 115 VAC receptacle. Two wires
are directly connected from the dry contact closure of the key system unit (KSU) to the DCI input terminals. An extra input terminal
is provided on the DCI so it can also be activated by 24VDC if available at the KSU or at an individual telephone station set. One pair
of wires is run from the DCI output terminals to the alerts, through modular telephone terminal blocks.
