INTRODUCTION

Model AD-3I and AD-3ILP Detectors from Siemens Industry, Inc. are System 3,

System PXL, System SXL-EX, System SXL, System XL3, System

CP-2ER, MXL Control Panel and MXL-IQ Control Panel compatible air

duct detectors. They are designed for use in heating, ventilating, and air

conditioning duct systems. Model AD-3I uses ionization smoke detectors,

and Model AD-3ILP uses photoelectric smoke detectors to detect the pres-

ence of combustion products in a duct system. (Refer to TECHNICAL

DATA below for information on compatible detectors.)

When smoke or combustion products are detected, shutdown of the duct

system and/or operation of supplementary equipment is provided by the

related system control panel.

INSTALLATION/WIRING INSTRUCTIONS Models AD-3I and AD-3ILP AIR DUCT DETECTORS INTRODUCTION Model AD-3I and AD-3ILP Detectors from Siemens Industry, Inc. are System 3, System PXL, System SXL-EX, System SXL, System XL3, System CP-2ER, MXL Control Panel and MXL-IQ Control Panel compatible air duct detectors. They are designed for use in heating, ventilating, and air conditioning duct systems.

TABLE 2 AD-3ILP COMPATIBILITY System/Module Compatible Detectors MXL/MXL-IQ Control Panel System XL3 (INX-3) ILP-1, ILP-2* ILP-1 *The ILP-2 is only compatible with MXL/MXLV Rev. 8.0 or greater firmware and MXL-IQ Rev. 3.0 or greater firmware. When the CSG-M is configured, the DUCT application must be selected. DO NOT USE air duct detectors with Alarm Verification.
PAGE 3
CAUTION: These air duct detectors are designed for detection and control of products of combustion in a duct system. They are not to be used for open area protection. OPERATION When the AD-3I/3ILP (AD-3I or AD-3ILP) is operating, a sample of air is drawn from the duct and passed through the sampling chamber at low velocity by means of the inlet sampling tube. The air sample passes through the smoke detector mounted in the duct housing and is exhausted back into the duct through the outlet sampling tube.
PAGE 4
MOUNTING THE AIR DUCT HOUSING Location on Duct System Locate the air duct detector in the main supply duct, downstream from the filters and positioned so as to operate reliably in case of smoke in any part of the air stream. In instances where filters are capable of removing smoke, install detectors both upstream and downstream from the filters. The air duct detectors use sampling tubes which monitor the full width of an air duct to overcome the limitations of spot-type smoke and heat detectors in the duct.
PAGE 5
Figure 2 Recommended Locations in Duct Systems Mounting of the Air Duct Housing (See Figure 3) a. Affix the adhesive backed gaskets (Item 1) to the back of the detector housing (2) so that the larger hole on the gasket lines up with the sampling tube hole on the sampling chamber and the smaller hole lines up with the housing mounting hole. b. Affix the adhesive backed template (5) to the side of the ductwork. c. Drill the four 0.110 diameter holes with a No.

Sampling Tube Selection There are four standard lengths of inlet sampling tubes. To ensure accurate air sampling, select the appropriate length and determine the outside width of the duct. Select the sampling tube nearest to, but greater than, the duct width (Table 5). The outlet sampling tube for all ducts is a fixed length of 4 inches (10.1 cm). Trim the inlet sampling tube at the job site as described below. TABLE 5 SAMPLING TUBE SELECTION CHART Outside Duct Width Sampling Tube Model No.
PAGE 8
Trimming the Inlet Sampling Tube (See Figure 4) a. Measure the outside width of the duct. b. Add 2.25 inches to obtain proper length of tube. Example: Outside width of duct Add 2.25 inches Length of sampling tube 2 ft 6 in + 2.25 in 2 ft 8.25 in The length (2 ft 8.25 in) determines (Table 5 on page 7) the model number of the appropriate sampling tube (STA-3). c. Measure the sampling tube, starting from the end with the four mounting holes. d.

Sensing Compartment Cover Installation a. Install the cover gasket (Figure 3, 16) on the housing, if not already installed. Be certain the alignment holes in the cover gasket are aligned with the guides on the housing. b. Install the sensing compartment ionization cover (17) when using DI-B3, DI-B3H, ILI-1B, or ILI-1BH detectors and the photoelectric cover (18) when using an ILP-1 or ILP-2 detector. c. Fasten the cover, using the No. 6 screws (19) provided.
