ADR-3000 – System Introduction
Revision 1.10 4 November 2004
4.2.6 ADR-810
Single-Channel Input Module
The ADR-810 interfaces non-addressable input (initiating) devices with the analog
addressable system. These devices can be conventional smoke, heat, and flame
detectors, beam detectors, gas detectors and water flow switches.
The ADR-810 should be connected to a 24 V
DC
source from the ADR-3000 or a
TPS-34A Remote Power Supply. The ADR-810 continuously monitors its power source
and reports any problem such as a blown fuse,
disconnection, or voltage drop.

The ADR-810 has a supervised 2 or 3-wire Class B
(NFPA 72 Style C) initiating device circuit (IDC). Use a
5.1 K
Ω
end-of-line resistor to terminate a two-wire
connection, or the 3W-EOL (end of line) module to
terminate a 3-wire connection.
The ADR-810 has a 24 V
DC
output that is current limited
by a 0.5 A fuse. This output is interrupted on reset,
which resets devices that are latched on alarm.
The ADR-810 has an on-board LED that flickers when
addressed by the control panel and latches on upon
alarm.

4.2.7 ADR-812 Two-Channel Input Module
The ADR-812 is a two-IDC, dual-channel input module that operates as an interface
between the ADR-3000 analog addressable control panel and compatible two-wire
conventional initiating devices. The two NFPA 72 Style C Initiating Device Circuits
(IDCs) occupy two consecutive addresses.
The ADR-812 should be connected to a 24 V
DC
source from the ADR-3000 or a
TPS-34A Remote Power Supply. The ADR-812 continuously monitors its power source
and reports any problem such as a blown fuse, disconnection, or voltage drop.
The ADR-812 reports the following trouble events and
conditions of the zone module: short-circuit, cutoff in the
IDC loop and 24 V
DC
input fault.

The ADR-812 has a 24 V
DC
resettable power limited
output. This output is interrupted upon Reset, in order to
reset devices that were latched on alarm.
The optional 3-wire connection allows connecting
detectors that have higher power consumption, such as
gas detectors or beam detectors.
The ADR-812 occupies two consecutive addresses, the
first of which is programmed by the PROG-4000.
Please refer to the ADR-812 technical manual for further
details.
