FUNCTION

The intelligent reﬂ ective beam detector is a compact

detector for detecting smoke in large open areas such

as atria, warehouses, theatres and churches. It also

has a built-in 20D negative bi-directional short circuit

isolator.

The transmitter and receiver form a single unit

mounted to a wall of the building. A reﬂ ector which

returns the IR beam from the transmitter to the

receiver is mounted on the opposite wall. In the event

of smoke partially obscuring the light an imbalance

between the transmitted and received light will occur.

On interrogation by the control panel the detector will

then transmit an alarm value.

The intelligent reﬂ ective beam detector is an addition

to the Apollo range and not a replacement for the

XP95 loop-powered beam detector.

FEATURES

The intelligent reﬂ ective beam detector is supplied in

two versions: one for use at distances of 5–50m from

detector to reﬂ ector and the other for distances of

50–100m.

The detector is factory set to a beam obscuration of

35% which is the best setting for most factories and

warehouses. The setting can be changed to 25% for

ofﬁ ces and clean areas such as theatres or to 50% for

hostile areas such as mills or foundries.

The detector compensates automatically for gradual

contamination of the lenses in order to avoid false

alarms.

INTELLIGENT REFLECTIVE

BEAM DETECTOR

Part nos

The detector is non-latching and resets 30 seconds

after an alarm event ceases and in 3 seconds after the

removal of a fault.

A termination backbox, part no 29600-241, is available.

This allows easy ﬁ rst ﬁ xing of the cabling and termina-

tions to the intelligent reﬂ ective beam detector. The

termination backbox can be surface or ﬂ ush mounted.
