3-3.15 Addressable Relay Output Devices
The addressable relay output device (P/N 70-408004-001) pro-
vides the
PEGAsys system with a Form “C” dry contact inter-
face for remote control applications. The device connects directly
to the RX/TX multiplex loop and contains an SPDT relay for
control of auxiliary equipment. The device can be activated
through the systems EOC or RTC programming and its default
operation programming is done during the Autolearn function.
The unit includes an intrinsic status LED which allows the de-
vice to indicate its present operating status. In normal standby
mode the LED will flash every 9 seconds, in trouble condition
the LED will be extinguished, in activated condition the LED will
flash every 2 seconds.

3-3.16 Model DH-2000 Air Duct Housing
The DH-2000 air duct housing is designed for detecting par-
ticles of combustion in air handling systems. Upon smoke de-
tection the system can be programmed to control a variety of
devices like HVAC fans and power shut down preventing un-
necessary damage to the facility.
The duct housing accepts either the PSD-7152 or CPD-7052
smoke detectors. A transparent Lexan cover over the detection
chamber allows visual inspection of the duct detector chamber
and the internal smoke detector status. Sampling of the air in
the duct is accomplished through the use of sampling tubes
which extend into the HVAC duct.

3-3.17 Loop Isolator Devices
The SmartOne series of loop devices offer optional loop isola-
tion which protects the loop from wire-to-wire short conditions
(NFPA 72 Style 7). The isolators will open the loop between two
isolators in the presence of a short circuit condition, thus allow-
ing the remainder of the loop to operate normally, however, a
trouble indication for the devices effected by the isolation will
be prompted on the panel. The isolators will return to normal
operation when the short condition has been removed from the
effected wires.
The loop isolators are offered in three package styles, one stand
alone style in a single gang electrical box arrangement, a sec-
ond in a detector base module arrangement which allows the
unit to be mounted behind a smoke detector in the 6” detector
base and a third which mounts directly on the RX/TX module.
The single gang mount unit includes intrinsic status LED’s which
allows the device to indicate in which direction the short condi-
tion is being detected. In normal standby mode the LED will be
extinguished, in activated condition the LED will be on continu-
ously.
