Easy Installation

and

move

more

quickly

through

the

installation

process.

False Alarm Reduction
DSC

is

committed

to

reducing

false

alarms

and

has

integrated

a

number

of

features

into

the

WS4936

to

provide

reliable

detection.

One

important

feature

is

drift

compensation.

It

provides

a

constant

level

of

sensitivity

performance

for

extended

operation.

As

dust

accumulates

in

a

detector

it

adjusts

to

maintain

the

original

factory-set

sensitivity,

thereby

minimizing

the

potential

for

false

alarms.

If

the

detector

reaches

its

limit

of

compensation,

it

will

indicate

a

trouble

condition

well

before

the

sensitivity

increases

to

a

level

where

false

alarms

will

be

generated.
