ADR-3000 – System Introduction
Revision 1.10 4 November 2004
4.2.8 ADR-818 Eight-Channel Input Module
The ADR-818 Interfaces 8 supervised non-addressable input lines to be connected to
conventional smoke detectors and water flow switches using a two-wire Class-B (NFPA
72 Style C) initiating device circuit (IDC).
The ADR-818 should be connected to a 24 V
DC
source from the ADR-3000 or a
TPS-34A Remote Power Supply. The ADR-818
continuously monitors its power source and reports
any problem such as a blown fuse, disconnection, or
voltage drop.

The ADR-818 occupies eight consecutive addresses,
the first of which is programmed by the PROG-4000.
The ADR-810 Single Channel Input Module, the
ADR-812 Two-Channel Input Module, and ADR-818
Eight-Channel Input module can be connected to the
following conventional Telefire detectors: TFH-220F;
TFI-330, TFO-440, and TPH-442. Telefire may
approve other compliant devices.

4.2.9 ADR-820
Single-Channel Output Module
The ADR-820 enables the connection of output devices such as alarm bells, horns,
extinguishers, strobe lights, etc., through a single
supervised output line, terminated by a 5.1 K
Ω
end-of-l
resistor.

In addition, the module has unsupervised dry contacts for other activation purposes.
Use these contacts to switch only low voltage circuits.
The ADR-820 has an onboard LED that flickers when addressed by the control panel
and latches on upon activation.
