Simplex 50RU, 100RU Installation Instructions Manual

UL, ULC, CSFM Listed; Reflective Beam Smoke Detectors
MEA (NYC) Acceptance* Fire Fighting Enterprises Models 50RU and 100RU

Features

Photoelectric transmitter and receiver are
combined in a single, compact housing:

 An infrared beam is reflected from a matching prism

with the reflected light analyzed by an on-board
microprocessor providing area smoke detection

 Two models are available:

– Model 50RU is for 15 ft to 160 ft (5 m to 50 m)
– Model 100RU is for 160 ft to 330 ft (50 m to 100 m)

 Each model includes the matching prism reflector(s),

a wall mounting bracket, and a calibrated test filter

 UL listed to Standard 268

Microprocessor controlled operation includes:

 Easy setup and alignment with three selectable alarm

thresholds of 25%, 35%, or 50% beam obscuration (can
be mounted horizontally or vertically)

 Operation at either 12 VDC or 24 VDC
 Alarm latching or alarm auto-reset
 Automatic gain control
 Separate alarm and trouble contacts

Applications:

 Open areas where ceiling height exceed 25ft (7.6 m)

(warehouses, hotel atriums, industrial plants, and school
gymnasiums)

 Public areas where cosmetics are of prime importance

and detector heads need to be small and unobtrusive
(shopping malls, libraries, theaters, and churches)

Benefits:

 Reduces installation costs where 6 or more spot

detectors are required in a single area

 Optional remote test station mounts at ground level and

reduces service time by testing without site disruption

Optional Accessories:

 Surface mount matching backbox
 Extended alignment bracket
 Remote Test Station

Description

Single Unit Design. A single unit houses both an

infrared transmitter and receiver. The transmitter signal is
reflected by a matching prism back to the receiver where
the internal microprocessor analyzes it for the presence of
smoke. An alarm condition is determined when the
selected sensitivity level is reached.

Mounting. Detectors are mounted with the beam
projecting between 1 ft (305 mm) and 2 ft (610 mm)
below, and parallel to the ceiling. Lateral detection may
be up to 30 ft (9.144 m) on either side of the beam,
providing a maximum total coverage area of up to
19,800 ft

Description (Continued)

Application Note. Reflective beam smoke detectors may

not be suitable for areas with highly reflective surfaces.
Separate transmitter/receiver models may be required.

Engineering Specification

The projected beam type smoke detector shall be a 4-wire
12/24 VDC device to be used with a UL Listed separately
supplied 4-wire control panel. Unit shall be listed to
UL 268 and shall consist of an integrated transmitter and
receiver. The detector shall operate between a range of
15 ft to 330 ft (5 m to 100 m). The temperature range of
the beam shall be -4° F to 131° F (-20° C to +55° C)
[UL 268 listed temperature range is 32° F to 100° F (0° C
to 38° C)]. The beam detector shall feature automatic gain
control which will compensate for gradual signal
deterioration from dirt accumulation on the lenses. The
unit shall include a wall mounting bracket. Testing shall
be carried out by using a calibrated obscuration test filter.
The Reflective beam type smoke detector shall be a Fire
Fighting Enterprises 50RU (160 ft/50 m) or 100RU
(330 ft/100 m).

Beam Detector Spacing

On smooth ceilings, up to 60 ft (18.288 m) between
reflective beams and not more than one-half the spacing
between a reflective beam and a sidewall. Other spacing
may be used depending on ceiling height, airflow
characteristics, and response requirements.

Refer to NFPA 72 and Installation Instructions supplied
with unit for further information.
