Three-Year Limited Warranty

System Sensor warrants its enclosed smoke detector to be free from de-

fects in materials and workmanship under normal use and service for a

period of three years from date of manufacture. System Sensor makes no

other express warranty for this smoke detector. No agent, representative,

dealer, or employee of the Company has the authority to increase or alter

the obligations or limitations of this Warranty. The Company’s obliga-

tion of this Warranty shall be limited to the repair or replacement of any

part of the smoke detector which is found to be defective in materials or

workmanship under normal use and service during the three year period

commencing with the date of manufacture. After phoning System Sensor’s

toll free number 800-SENSOR2 (736-7672) for a Return Authorization

number, send defective units postage prepaid to: System Sensor, Repair

Department, RA #__________, 3825 Ohio Avenue, St. Charles, IL 60174.

Please include a note describing the malfunction and suspected cause

of failure. The Company shall not be obligated to repair or replace units

which are found to be defective because of damage, unreasonable use,

modifications, or alterations occurring after the date of manufacture. In no

case shall the Company be liable for any consequential or incidental dam-

ages for breach of this or any other Warranty, expressed or implied what-

soever, even if the loss or damage is caused by the Company’s negligence

or fault. Some states do not allow the exclusion or limitation of incidental

or consequential damages, so the above limitation or exclusion may not

apply to you. This Warranty gives you specific legal rights, and you may

also have other rights which vary from state to state.

This smoke detector is designed to activate and initiate emergency ac-

tion, but will do so only when it is used in conjunction with an authorized

fire alarm system. This detector must be installed in accordance with

NFPA standard 72.

Smoke detectors will not work without power. AC or DC powered

smoke detectors will not work if the power supply is cut off.

Smoke detectors will not sense fires which start where smoke does

not reach the detectors. Smoldering fires typically do not generate a lot

of heat which is needed to drive the smoke up to the ceiling where the

smoke detector is usually located. For this reason, there may be large de-

lays in detecting a smoldering fire with either an ionization type detector

or a photoelectric type detector. Either one of them may alarm only after

flaming has initiated which will generate the heat needed to drive the

smoke to the ceiling.

Smoke from fires in chimneys, in walls, on roofs or on the other side of a

closed door(s) may not reach the smoke detector and alarm it. A detector

cannot detect a fire developing on another level of a building quickly or

at all. For these reasons, detectors shall be located on every level and in

every bedroom within a building.

Smoke detectors have sensing limitations, too. Ionization detectors and

photoelectric detectors are required to pass fire tests of the flaming and

smoldering type. This is to ensure that both can detect a wide range of

types of fires. Ionization detectors offer a broad range of fire sensing ca-

pability but they are somewhat better at detecting fast flaming fires than

slow smoldering fires. Photoelectric detectors sense smoldering fires bet-

ter than flaming fires which have little, if any, visible smoke. Because fires

develop in different ways and are often unpredictable in their growth, nei-

ther type of detector is always best, and a given detector may not always

provide early warning of a specific type of fire.

In general, detectors cannot be expected to provide warnings for fires

resulting from inadequate fire protection practices, violent explosions,

escaping gases which ignite, improper storage of flammable liquids like

cleaning solvents which ignite, other similar safety hazards, arson, smok-

ing in bed, children playing with matches or lighters, etc. Smoke detectors

used in high air velocity conditions may have a delay in alarm due to

dilution of smoke densities created by frequent and rapid air exchanges.

Additionally, high air velocity environments may create increased dust

contamination, demanding more frequent maintenance.

To keep your equipment in excellent working order, ongoing maintenance

is required per the manufacturer’s recommendations and UL and NFPA

standards. At a minimum, the requirements of Chapter 7 of NFPA 72, the

National Fire Alarm Code, shall be followed. A preventative maintenance

agreement should be arranged through the local manufacturer’s represent-

ative. Though smoke detectors are designed for long life, they may fail at

any time. Any smoke detector, fire alarm equipment, or any component of

that system which fails shall be repaired or replaced as soon as possible.

WARNING

The Limitations of Property Protection Smoke Detectors

NOTE: (Model 2100TD only) Before removing the de-

tector cover, note the position of the thermistors.
Make sure the thermistors are not bent over when
the housing is replaced.

1. Remove detector housing by gently prying the four hous-

ing tabs on the bottom of the base with a small-bladed
screwdriver and pull the housing from the base. Use cau-
tion to avoid damaging the thermistors (2100TD only).

2. Vacuum the screen carefully without removing it.
3. Remove screen assembly, pulling straight out (see Figure

5).

4. Remove the sensing chamber cover.
5. Clean the sensing chamber by vacuuming or blowing out

dust and particles.

6. Replace the sensing chamber cover, aligning the arrow

on the cover top with the arrow on the printed circuit
board.

7. Replace the screen by placing the screen assembly over

the sensing chamber cover and twisting until it snaps
into place.

8. Replace the housing by aligning the three triangular

slots on the base with their counterparts on the housing.

Figure 5. Removal of cover and screen for cleaning:

Gently press the housing until it locks in place. Check
to make sure that the thermistors are in the upright po-
sition (2100TD).

9. Reinstall the detector.
10. Notify the proper authorities the system is back in op-

eration.
