COMMMISSIONING

MADE EASY

Orbis has been designed with a number

of features that make commissioning

easier and that save time.

StartUp

When Orbis detectors are powered up

they automatically enter a phase known

as StartUp and in which they stay for 4

minutes. After this they revert to normal

operation. If the detector is reset, ie, if

power is disconnected for one second

or longer, the detector will always enter

StartUp for the first four minutes after

power has been restored. The detector

LED flashes red once a second to indicate

that it is in StartUp.

What StartUp indicates

StartUp is used to check that the positive

and negative cables are connected in the

correct polarity and that power has been

applied to the detector. If this is the case,

the LED will flash red once a second.

StartUp will not check whether the IN+

and OUT+ connections have been

transposed. This is not a problem if

standard bases are used as the detector

will operate normally.

If, however, diode bases are used and

a detector is removed from a base with

transposed positive connections none

of the detectors beyond this point will

operate.

FasTest®

Orbis detectors incorporate a test facility

known as FasTest®.

In normal operation Orbis smoke

detectors do not change to the alarm

state at the first sensing of smoke.

they did, they could be too sensitive and

cause false alarms. Algorithms determine

the point at which the detector changes

to alarm.

T h i s c o u l d s l o w d o w n r o u t i n e

maintenance during which detectors are

tested by means of smoke or a smoke-

simulating substance.

In order to avoid such a problem Orbis

detectors have FasTest, a facility which

is automatically available during StartUp

and which modifies algorithms so that

testing is possible within 4 seconds.

The problem of testing is even more

acute in the case of heat detectors as they

absorb a great deal of heat during testing.

Orbis heat detectors also incorporate

FasTest®.

In the case of heat detectors a fast test is

defined as a sample which recognises a

rise of 10°C within one minute. Since

sampling takes place every 2 seconds an

Orbis heat detector will respond within

about 4 seconds.

Smoke or Heat Testing

Smoke or heat testing Orbis detectors is

aided by the FasTest® feature. A detector

will react rapidly to the correct stimulus if

applied within 4 minutes after power up.

Choose the appropriate test function on

the control panel and reset the detector

circuit. This should place the detectors

into FasTest®. Apply smoke or heat as

appropriate and the detector should

enter the alarm state within 4 seconds.

The panel may sound the alarm and reset

the zone automatically (refer to control

panel's instructions). If not, silence the

alarm and reset the panel. Repeat the

procedure as necessary.

Note that the multisensor detector will

respond to either smoke or heat while

in FasTest®.

MAINTENANCE AND

SERVICING

Detectors should be checked regularly

at the intervals indicated by the locally

applicable code of practice. Apollo

recommends that detectors be checked

at least once a year.

One of the features of Orbis is FasTest®

which makes it possible to carry out

a functional test, using smoke or heat,

within about four seconds. If detectors

appear not to be functioning correctly

they should be returned to Apollo for

testing.

If detectors are externally dirty they

can be cleaned carefully with a damp

cloth using a small amount of industrial

alcohol.

DirtAlert™

Orbis detectors have drift compensation

to compensate for changes caused by the

environment. The most usual change is

contamination.

If the detector is dirty to the point where

it can no longer compensate, its LED

will flash yellow while it is in StartUp.

Maintenance checks should therefore

include removing a detector from its base

and re-inserting it or pressing reset on the

panel to initate StartUp.

CONVENTIONAL DETECTORS

A flashing yellow LED is not a sign

that the detector needs to be replaced

immediately. The decision to replace

should be taken by the service engineer,

taking the environment of the detector into

account. If the detector is not replaced it

will evenually cause false alarms.

When deciding how long to leave the

detector on site in such a case, the

following rule of thumb may be used:

installation time + 25%

For example, if a detector had been

installed for four years when the LED

flashed yellow, it could be left in place

for up to 12 months.

Dirty detectors can be returned to Apollo

for cleaning and recalibration.

APPROVALS AND

REGULATORY

COMPLIANCE

The Orbis range of detectors is approved

by a large number of certification bodies.

These include approvals to EN54:200

with LPCB, Vds, DIBT, BOSEC and FG.

by Apollo contact the Sales Department

or visit our website (details on page 2).

EU DIRECTIVES

Orbis complies with the requirements of

a number of European New Approach

Directives such as the EMC Directives

2004/108/EC and the Construction

Products Directive 89/106/EEC. Visit

the Apollo website to download EC

certificates of conformity issued by

the Notified Body, LPCB. Copies of

Declarations of Conformity issued by

Apollo for all applicable New Approach

Directives are available on the Apollo

website or from Apollo on request.

All Orbis products comply with the

marking requirements of the WEEE

Directive, 2002/96/EC. For further
