G . Put the battery holder back in, re-mount the battery

compartment lid and re-attach it with the screw. With

correctly inserted fresh batteries and tight closure of

the lid, the TROUBLE indicator should extinguish.

H . Put back the battery area cover - insert the angled legs

at the left edge into their holes and then press the right

edge of the cover against the cabinet surface until the

catches click into place.

I . The “MEMORY” message will continue blinking in the

display (caused by the “tamper” alarm you triggered).

Clear it by arming the system and disarming it as soon

as the exit delay starts.

9.2 Replacing Batteries in Wireless

Devices

The wireless sensors supplied with your system are

TL-5902) that last several years, depending on the number

of times the sensor is triggered into transmission. The

SPD-1000 artwork protection detector is powered by two

3V/160 mA long life (5 years) Lithium batteries.

However, if and when a battery becomes weak, the sensor

itself sends a “low battery” message to the control panel,

and a low battery trouble message is displayed together

with the zone information (see Para. 5.2).

The keyfob transmitters used to control the system are

about one year if you do not press a button more than 10

times a day. Battery exhaustion is clearly evident by

flashing of the transmitter’s red indicator while the button

is pressed (instead of lighting steadily).

When a low battery indication appears for the first time, it

may be considered as a pre-warning. It normally gives you

ample time (about 30 days) to obtain a new battery and

replace the old one, and the detector or keyfob unit will be

fully operational throughout this period. However, to be on

the safe side, it is advisable not to wait that long.

Use the battery specified in the detector’s own installation

instructions. If you do not have the instructions, seek the

advice of your installer or ask him to replace the battery in

the specific device that sent the low battery message.

After battery replacement, the detector unit will send a

“battery restored” signal to the control panel, and the “low

battery” message will be cleared.

9.3 Periodic Testing

The components of your security system are designed to be

maintenance-free as much as possible. Nevertheless, it is

mandatory to perform a “walk test” at least once a week and

after an alarm event to verify that all system detectors

function properly. Proceed as described in Para. 6.7, and

If there is any problem, notify your installer at once.

9.4 Cleaning the Control Panel

The control panel may occasionally get stained if touched

with greasy fingers, and may accumulate dust after a long

period of use. Clean it only with a soft cloth or sponge

moistened lightly with a mixture of water and mild

detergent, and then wipe it dry.

The use of abrasives of any kind is strictly forbidden.

Also never use solvents such as kerosene, acetone

or thinner. These will certainly ruin the external finish

and damage the transparency of the top window.

10. PERFORMANCE LIMITS

Although the alarm control system you purchased is highly

reliable, it does not guarantee protection from burglary and

fire hazards. Even the most advanced systems can be

defeated or might occasionally fail to warn. Some of the

reasons for this are:

Sloppy maintenance: If the system is used over a long

period of time without testing, a key element such as a

detector or a siren might go wrong without any visible or

audible signs of failure. If a low battery warning is

neglected, there will be no backup power to keep the

system operational during a power outage.

Power failures: In case of prolonged absence from the

protected site, the mains supply may suddenly fail (an

earth leakage protection relay may trip, disconnecting the

mains supply). After such an event, the alarm system will

draw power from the backup battery, until all reserve

power is exhausted, leaving the premises without

protection.

Telephone line trouble: Telephone lines may be

disconnected or short circuited. With the telephone line

"down", your alarm system will not be able to report events

to the central station.

Sirens do not always wake up sound sleepers: Sirens

and bells installed outside or far from bedrooms are not

likely to awaken people who are sound asleep behind

closed doors inside the protected area or in adjacent

buildings.

The system is sometimes defeated: With sufficient

technical know-how, intruders may find a way to defeat

various types of sensor or disconnect warning devices.

Intruders may also take advantage of unprotected

openings and skylights, or even enter forcibly at

unpredictable spots.

Smoke detectors have their limits: In many cases,

smoke detectors fail to warn on time because the fire

started at a different level of the house, or too far away

from the detector.

All this gives sufficient proof that even with a good

alarm system installed, there is still need for life and

property insurance. In addition, users should test their

alarm systems at regular intervals, to make sure that

malfunctions are detected before a true alarm event

occurs.
