Installation Instructions

Before installing sensors, please thoroughly read the Guide for Proper Use of System Smoke Detectors, which provides detailed infor-
mation on sensor spacing, placement, zoning, and special applications. Copies of this guide are available from Honeywell.

NOTICE: This manual should be left with the owner/user of this equipment.
IMPORTANT: This sensor must be tested and maintained regularly following NFPA 72 requirements. It should be cleaned at least once

a year.

GENERAL DESCRIPTION

Filtrex® uses a small air intake fan and a high density replaceable filter. Air and smoke are drawn into a photoelectric sensing cham­ber while airborne particulate and water mist are removed. The addressable-analog detector transmits an analog representation of
smoke density over a communication line to a control panel. Rotary-decade switches are provided for setting the sensor’s address.
Two LEDs on the sensor are controlled by the panel to indicate sensor status.

The Filtrex smoke detector is intended for use in normal environmental conditions, where dust and other airborne particulate are pres­ent at elevated levels. These elevated levels tend to cause false alarms and high maintenance in standard detectors. Filtrex provides
a protective enclosure for a photoelectric smoke detector chamber and allows smoke detection in areas where heat detection was the
only practical alternative for fire sensing.
Filtrex requires compatible addressable communications to function properly. Connect this detector to listed-compatible control panels
only.

WARNING

CAUTION

WIRING INSTRUCTIONS

All wiring must be installed in compliance with the National Electrical Code, applicable local codes, and any special requirements of
the Authority Having Jurisdiction. Proper wire gauges should be used. The installation wires should be color-coded to limit wiring mis­takes and ease system troubleshooting. Improper connections will prevent a system from responding properly in the event of a fire.

NOTE: Although the TC8441007A is an intelligent sensor, a separate pair of wires is required for power. This power must be provided
from a listed fire alarm power supply.

Remove power from the communication line before installing detectors.

All wiring must conform to applicable local codes, ordinances, and regulations.

1. Wire the sensor base per the wiring diagram, please see Figure 1.

2. Set the desired address on the sensor address switches, please see Figure 2.

3.

Insert 5-wire connector on mounting base into 5-pin connector on Filtrex unit. Install the detector into the sensor base. Push the
detector into the base while turning it clockwise to secure it in place. (Please see Figure 5 and INSTALLING FILTREX INTO BASE
on page 4 for specific directions.)

4. After all detectors have been installed, turn on the detector power supply, then apply power to the control unit and activate the
communication line.

5. Test the detector(s) as described in the

TESTING

Before testing, notify the proper authorities that the system is undergoing maintenance, and will temporarily be out of service. Disable
the system to prevent unwanted alarms.
All detectors must be tested after installation and periodically thereafter. Testing methods must satisfy the Authority Having Jurisdiction
(AHJ). Detectors offer maximum performance when tested and maintained in compliance with NFPA 72.
The sensor can be tested in the following ways:

A. Functional: Magnet Test (P/N M02-04-01 or M02-09-00)

This detector can be functionally tested with a test magnet. The test magnet electronically simulates smoke in the sensing cham

ber, testing the detector electronics and connections to the control panel.

1. Hold the test magnet in the magnet test area as shown in Figure 3.

2. The detector should alarm the panel. Two LEDs on the detector are controlled by the panel to indicate sensor status. Coded

signals, transmitted from the panel, can cause the LEDs to blink, latch on, or latch off. Refer to the control panel technical
documentation for detector LED status operation and expected delay to alarm.

B. Smoke Entry: Aerosol Generator

Aerosol generators for smoke entry testing are available from a number of third party manufacturers (e.g., Gemini Scientific).

Following the manufacturer’s instructions, apply aerosol until the panel alarms.

A detector that fails any of these tests should be retested. If the detector still fails any test, have its filter replaced (see instructions
below) and retested. Finally, if the detector continues to fail after replacing the filter, it must be returned for repair or replacement.
When testing is complete, restore the system to normal operation and notify the proper authorities that the system is back in opera­tion.

TESTING

The unique design of Filtrex eliminates the need for typical detector cleaning. The only maintenance necessary is replacing the fil­ter, which is signaled by a trouble condition at the panel (see below).
Filtrex has been designed to maximize the amount of time before maintenance is required. Filtrex utilizes a replaceable filter that may
become clogged over time. Filtrex detector monitors itself to insure that the filter has not become clogged. Because environmental
conditions can vary significantly, the amount of time before maintenance could vary significantly as well. To fully understand mainte­nance requirements of Filtrex in its installed location, it is recommended that the
following test program be conducted.

1. Install the Filtrex detector in the desired location.

2. Connect the Filtrex detector to the fire alarm control panel.

3. Maintain a record for at least 90 days of any maintenance performed on or required by Filtrex.

4. At the end of the test period, use the record to develop and schedule maintenance. Filtrex should be serviced at regular intervals
to insure that the fire alarm system provides continuous protection

Filtrex is not designed to operate in explosive environments.

Dust cover must be removed before the detector can sense smoke.
