1. OVERVIEW

FLS-02EC(-H2) Explosin Proof Smoke Detector has Division and Zone explosion-proof ratings. This

detector is a sensor of the smoke using the scattered light, detecting the scattering of the light

reflected by the smoke. There are light emitter (Infrared LED) and the detector (photo-diode) inside,

the former emits the light through the lens, and the latter detects the light scattered by smoke to

detect the smoke in the hazardous area. This detector outputs include a localized LED, and relays.

An example of the installation location of this detector is as follows:

Battery rooms

Combustible storage facilities

Chemical plants

Engine room, etc

2. FEATURE

Since the structure is pressure-resistant, explosion-proof, it can be fitted in a hazardous area

It also tolerates the hydrogen explosion.

FM Approved for use in Class I, Division 2 hazardous locations. and FM Approvals for smoke

detector.

IECEx & ATEX Zone approved

LED provides detector status.

5.3. Automatic Test Function

Every hour, detector supervises changes of smoke signal due to aging and dirt of sensor. When

changes of smoke signal reaches to the limit, it will result in Trouble condition.

And, detector supervises the light emission state of detection area every 24 hours (and after 60

seconds since turning on the power). When detection area is light out, it will result in Trouble

condition.

6. INSTALLATION

・FLS-02EC(-H2) must be properly installed and used according to this manual and the

specific approval certificates. Improper installation and use will invalidate warranty and

product certifications.

・Do not disassemble or repair the detector without permission. Detector repair should be

performed only by the manufacturer.

・Be certain that installation complies with all local codes. If you have questions, consult

the authority having jurisdiction before installation the system.

・Please install the detector after turning off the power.

・The FLS-02EC and FLS-02EC-H2 include flameproof joints, consult Fenwal Control of

Japan if repair of the flameproof joints is necessary.

6.1. Installation Environments

1. Temperature : 0 to +50 degree C

2. Humidity : 30 to 85%RH（However, no condensation）

3. Caution :

・Installed Indoors

・Avoid drops of water, moisture, corrosive gases, and vapors of organic solvents.

・Avoid direct sunlight and radiation by high temperature.

・The Dust Cover (see Figure 2) keeps dust and particles out of the smoke chamber that may

enter. Don't remove it until installation is over.

Figure 2 : Dust Cover

6.2. Mounting

1 ) Fix the FLS-02EC(-H2) to the wall with four M5 or M6 bolts using base 4-φ7 hole (See Figure 3) .

bolt length more than 11 (eleven) mm. It must be mounted on a ceiling or wall of sufficient

strength to support the weight.

2 ) It is normally mounted on the ceiling no less than 0.6 m ( twenty-four inch ) from a side wall, and

vice versa (See Figure 3).

The diameter of usable wiring is as follows.

Wiring Diameter : (Minimum) 0.2mm2 (Maximum) 2.5mm2

Case of AWG : (Minimum) 24 (Maximum) 12

The screws must be tightened down with a torque 0.5 to 0.6 N•m.

The environmental specification of the cable should be sufficient to withstand the surrounding

environment.

6.3.2. Procedure

1 ) Install the base according to "6.2 Mounting", and complete the installation of the system conduit.

Insert the external cable within the base and close the unused NPT1/2 or M20 entry with the

plug (See Figure 5). Conductor insulation of external wiring should be stripped off with a bare

conductor length of about 0.3 inch (7 mm)

Figure 5 - Install Base

Be certain that wiring complies with all local codes. If you have questions, consult

the authority having jurisdiction before wiring the system.
