1-4.6 Duct Housing, Model DH-2000
The Model DH-2000 Duct Housing is used to enclose an intelligent smoke detector that
is monitoring for smoke in an air duct and is located outside of the duct. The duct housing
is used with inlet and outlet tubes that allow the air in the duct to be sampled uniformly
and transported to the enclosed smoke detector for obscuration-level measurement.

SMARTONE ADDRESSABLE MODULES

SmartOne addressable modules are of three general types:
• Monitor Modules. These modules provide a uniquely-identifiable interface between the
ARIES and an initiating device.
• Relay Module. This module supplies an unpowered, Form-C contact at a point-specific
address.
• Control Modules. These modules provide a uniquely-identifiable interface between the
ARIES and conventional notification appliances such as horns and strobes.
Each addressable module continuously transmits its current status to the ARIES Control Unit via
the signaling line circuit, and responds to control unit polling, inquiries, and activation
commands by the address that is set in the module using the Handheld Programmer,
P/N 74-200013-001, or using the ARIES's display.
1-5.1 Addressable Monitor Module, Model AI
Two styles of Model AI Addressable Monitor Modules are available: The Model AI (NO)
P/N 70-4070X8-001 is used to monitor conventional, unpowered, normally-open contact-
type devices such as manual stations, waterflow switches and supervisory switches
through a Class B initiating device circuit. The Model AI (N.C.), P/N 70-407008-002, is
intended for use within control equipment providing the normally closed trouble contact
and is not considered an initiating device circuit.
The AI Modules are designed to be mounted in the electrical box of the device being
monitored.
P/N 06-236530-001
Model PSD-7140 Photoelectric Detectors may be used with the ARIES Control
Unit.
