SECTION 1: FAMILIARIZATION

1.1 Introduction

The Model SS2 Multi-Spectrum Electro-Optical Fire/Flame Detectors may

be used in the FS2000 Fire Early Warning System or in the Stand-Alone

mode. Detectors of this model are housed in Explosion-Proof Class I, Div.

1 enclosures. The only difference between an FS2000 System Model SS2

Detector and a Stand-Alone SS2 Detector is in the wiring. The wiring

differences are described in Sections 1.2 and 1.3.

Model SS2-A Detectors have a latching relay. They are used for

hydrocarbon and non-hydrocarbon fires

Model SS2-AN Detectors have a non-latching relay. They are otherwise

identical to the SS2-A.

Model SS2-AH is the same as Model SS2-A except for the programming to

assure High Speed millisecond response to non-UV emitting sodium azide

fires (in addition to the normal fire response) for air bag industries. The

Detector is housed in a Class I, Div. 1 Explosion-Proof enclosure. For more

information, refer to corresponding specification sheets.

Model SS2-AM is the same as Model SS2-A except for the programming to

assure Ultra High Speed millisecond response to normal non-sodium azide

burning materials radiating UV and IR energy for munitions and air bag

industries. The Detector is housed in a Class I, Div. 1 Explosion-Proof

enclosure. For more information, refer to corresponding specification

sheets.

There are operational advantages when the Detector is connected to an

FS2000 Controller and FireBus. The Detector also has flexibility to be re-

configured in the field. It is simple to install and operate due to built in self-

testing. The maintenance consists in wiping the lens and performing

periodic testing required by the manufacture of the Fire Control and

Suppression Systems.

configured in the field. The maintenance consists in wiping the lens and

performing periodic testing required by the manufacture of the Fire Control

and Suppression Systems.

1.2 Stand-Alone Operation

The Model SS2 Detectors may be connected to an approved Fire/Security

Panel for Stand-Alone operation. The Detectors operate on 24 Volts DC. In

this mode the Detectors utilize Fire and Fault relays to interface to FM/UL

approved Fire/Security Panels. For Stand-Alone operation, the Detector’s

Fault relay is automatically configured by the on-board microprocessor.

The input current of the Detector is about 15 mA higher in the Stand-Alone

mode compared to operation as part of FS2000 System.

OPERATOR MANUAL // SECTION 1: FAMILIARIZATION

HONEYWELL 6

1.3 FS2000 System Operation

For FS2000 System operation, the Detector’s Fire and Fault signals are

sent digitally to the FS2000 System Controller using the four wire FS2000

FireBus. The FireBus provides the 24 Volts DC power for the Detector and

RS-485 digital communication (Refer to Honeywell Analytics document

MN0003: "FS2000 FIRE EARLY WARNING SYSTEM - INSTALLATION and

OPERATIONS GUIDE"). For special remote alarm applications, users may

also connect directly to the Detector’s Fire alarm relay.

NOTE: When the Model SS2 Detector is connected to the FS2000

System using FireBus communication, the Controller automatically

de-energizes the Detector’s Fault relay.

1.4 Overview

1.4.1 Model SS2 Detector Status Indications

The Model SS2 Multi-Spectrum Optical Fire/Flame Detectors are

microprocessor-based devices, which see ultraviolet (UV), visible (VIS),

and infrared (IR) spectral regions. The Detector's logic processor is

capable of quick response to fires while virtually eliminating false alarms.

The Model SS2 Detector has a 120° field-of-view.

There are two (2) LEDs on the Model SS2 Detector for indication of the

Detector status. During Normal Operation both LEDs will blink every 10

seconds.

If a Model SS2 Detector has a Fault, it de-energizes the Fault relay and

turns one (1) LED on. (The LED will not light if the Fault is a “No Power

Fault”). If the Fault condition, such as a “Low Voltage Fault”, is eliminated,

the Detector will automatically return to Normal Operation.

Faults caused by Excessive Input Voltage or temperatures outside the

operating temperature range require factory re-certification. Both LEDs

rapidly blinking (with frequency about 2 Hz) indicate faults requiring re-

certification.

If a Model SS2 Detector alarms to a fire, it energizes the Fire relay and

turns on both LEDs in the following sequence. One LED is turned on

immediately and the second LED will rapidly blink for several seconds

indicating that the Detector's FirePic is being permanently stored in the

Detector's solid-state memory. (FirePic is the several seconds of Detector

data, which precede an alarm event.)

1.4.2 Detection Range

The detection range of the detector is 60 feet to an industrial standard of

one square foot gasoline pan fire within 5 seconds.

1.4.3 Field-of-View

The Detector incorporates a minimum 120-degree conical Field of View.

The fire emissions received by the Detector diminish at extreme edges of

HONEYWELL 7

the field-of-view. For the fastest response times to the smallest size fire,

the Detector should be pointed to the fire threat area. When multiple

detectors are used to cover large areas, the Fields-of-View should overlap.

The Field-of-View is not limited to 120 degrees. Larger fires outside

120 Degrees

1.5 Testing

1.5.1 Special Conditions for Testing

The SS2 Detector should be tested immediately after installation, after

repair or maintenance involving wiring or module replacement, after

periodic maintenance, or after lens contamination has been identified.

1.5.2 Automatic Testing

The Model SS2 Detectors contain an internal source for self-testing. For

testing the Model SS2 Detectors end-to-end for both optical path and

window cleanliness, use a Honeywell Analytics Model FT-2045 Test Lamp.

1.5.3 Manual Testing

For manual testing the Detector may be exposed to an actual industry

standard open flame or to a Test Lamp simulating a fire. For Honeywell

Analytics model SS2 Multi-Spectrum Fire Detectors, it is mandatory to use

the handheld UV/IR Test Lamp, Model No FT-2045 or FT-2145.

NOTE: Other manufacturers UV/IR Test Lamps should not be

utilized to test Honeywell Analytics Detectors, and Honeywell

Analytics Model FT-2045 and FT-2145 Test Lamps should not be

utilized for testing other manufacturer’s Detectors.

OPERATOR MANUAL // SECTION 1: FAMILIARIZATION

HONEYWELL 8

The FT-2045 and FT-2145 Test Lamps are housed in an Explosion-proof

enclosure, powered by internal rechargeable batteries, and designed for

indoor and outdoor use. For additional information on the Test Lamp, refer

to Honeywell Analytics Specification SP0242 for the FT-2045 or 1505-008A

for the FT-2145.

SECTION 2: INSTALLATION

2.1 Installation Procedure

This section describes the installation of the Model SS2 Detectors for the

Stand-Alone mode. Utilization of junction boxes is recommended for the

Detectors wiring.

2.1.1 Installation Precautions

The following precautions should be observed during installation of Model

SS2 Detectors.

1. Make sure that external electrical power is turned OFF before connecting to

the Detector.

2. Do not handle the Detector's module (with its printed circuit boards)

without grounding. Printed circuit board components are susceptible to

damage from electrostatic discharge.

2.1.2 Conduit Installation

The following recommendations should be observed when planning

conduits.

1. In case only one of the two 3/4 inch NPT conduit openings on the Detector

enclosure is used, seal the unused opening with a threaded plug and

approved sealing material.

2. In areas where moisture may accumulate, install an approved conduit trap

or drain.

3. For applications requiring a Class I, Div. 1 Explosion-Proof rating, install a

seal within 6 inches of the enclosure.

4. Consult the manufacturer for dimensional information on the flameproof

joint specifications.

2.1.3 Wiring Recommendations

Install a junction box near each Detector location. Wire each Detector to

the junction box. Use screw-down terminal strips inside the junction box to

make the connections to the Detector's terminals and an Approved Fire

Alarm Panel. Use only approved junction boxes and terminal strips.

Avoid wire splices. However, if wire splices are necessary, Honeywell

Analytics recommends soldering all splices. The use of good wiring

practices will greatly improve the ease and reliability of installation, and

facilitate servicing.

2.1.4 Power Supply Considerations

Model SS2 Detectors use 24 Volts DC at a maximum current of 75

milliamps. Make sure that the Panel's power supply can handle the current

load of the total number of Detectors connected to it. For example, if 10

Detectors are used on one Panel's power supply, (multiply 75 mA 10 times)

the Panel's power supply must be able to handle at least 750 mA (0.75 A).
