Overview
Operation
The EC-50R/-100R comprises a transmitter and receiver in a
single enclosure and is usually installed between 19 inches and
24 inches below the ceiling. The transmitter emits an invisible
infrared light beam that is reflected via a prism mounted directly
opposite and with a clear line of sight. The reflected infrared light
is detected by the receiver and analyzed. Smoke in the beam path
will reduce the received infrared light proportionally to the density
of the smoke. The detector analyzes this attenuation or obscuration of light and acts accordingly. Detectors are typically mounted
within ±30 feet (9.14 m) of a potential fire source. Consult your
Authority Having Jurisdiction for spacing requirements specific to
your locality.
Alarm Threshold: Alarm thresholds of 25%, 35% and 50%
obscuration can be selected to suit the environment, with 25%
the most sensitive setting. The factory default setting is 35 percent
and is used for most typical applications. If the received infrared
signal reduces to below the selected threshold for approximately
10 seconds, the fire relay is activated.
Standard Features
Trouble Alarm: If the infrared beam is obscured rapidly to a level
of 90% or greater for approximately 10 seconds, the Trouble relay
is activated. Typical causes of trouble include an object being
placed in the beam path, transmitter failure, loss of the prism, or
sudden misalignment of the detector. The Trouble relay will reset
within 2 seconds of the trouble being cleared.
• Coverage: 50R range 15 -160 ft (4.6 - 48.8 m);
100R range 160- 330 ft (48.8 - 100 m)
• Microprocessor controlled
• Automatic drift compensation
• Simple alignment
• Selectable alarm thresholds
• 24 Vdc operating voltage
• Latching or non-latching operation
• Low current consumption
• Optional Ground Level Test Station

Fire Alarm: There are two modes to the operation of the fire
relay. Auto reset mode will reset the fire relay 5 seconds after the
received infrared signal has recovered to a level above the Alarm
threshold. Latching mode holds the fire relay active indefinitely
after an Alarm condition has occurred. To clear the latched mode,
power must be removed from the Detector for a minimum of 5
seconds.
Automatic Gain Control (AGC): The Detector monitors long
term degradation of signal strength caused by component aging
or build up of dirt on optical surfaces. By comparing the received
infrared signal against a standard every 15 minutes, the detector automatically compensates for signal differences of less than
0.7dB/hour. When the detector is showing AGC fault, detector is
still capable of generating an alarm, and will display both Alarm
and Trouble indications.

An infrared signal is projected out of the transmitter optics to the
reflector placed at the opposite end of the detection zone. The
signal is reflected back to the receiver where it is analyzed for fire
and trouble. The EC-50R/-100R must be positioned correctly to
minimize the detection time. The maximum lateral distance either
side of the beam is found to be typically 30 feet (9.1 m) for satisfactory detection under flat ceilings, providing a total area coverage of 19,800 square feet (60 feet x 330 feet), or 1844 square
metres (18.3 x 100.6 m).
Smoke stratification may be overcome by mounting multiple beam
detectors at different heights, one of which will project an infrared
beam below the heat layer and into the smoke layer.
EC-50R detectors should be mounted between
15 and 160 feet (4.6 and 48.8m) from a single
reflector.

Reflective beam smoke detectors are ideal for large open areas
such as warehouses, hotel atriums, industrial plants and school
gymnasiums.
Mount the reflector(s) on a secure surface directly opposite the
detector. Ensure that there is a clear line of sight between the
detector and the reflector(s), and that no moving objects such as
doors or mechanical equipment interfere with the beam path. All
objects should be kept a minimum of 19 inches (483 mm) away
from the center of the detector beam down the entire length of the
beam path. Reflectors should not be mounted on glass or reflective surfaces.

EC-100R detectors should be
mounted between 160 and 330 feet
(48.8 and 100.6 m) from a group of
four reflectors.
Detection time will be longer in a building with a peaked roof if a
fire occurs at the fringes of the protected area. If in doubt conduct
appropriate smoke tests.

Test Filter: A test filter is supplied with the detector, which is used
to verify the alarm threshold. See the installation sheet for details
on testing and calibration.
Because of the reflecting properties of the beam, all objects must
be kept a minimum of 19 inches (483 mm) away from the centre
of the beam path down the entire beam length. If highly reflective
surfaces are close to the beam, then greater clearances should be
applied.

Connection between the test station and the detector is made
by means of a 2-wire data link cable. The test station requires a
10.2 - 30 Vdc power connection.
The recommended installation height is approximately 19 to 24
inches (483 to 610 mm) below the ceiling. However, in all installations the National Fire Standards for that country/state must be
consulted.
4”
(102 mm)
When the test station key is inserted and turned to the Test
position, the Power LED flashes to indicate that power is connected and that the 2-wire data link cable is correctly installed.
After several seconds in the test position, the test station initiates
an alarm at the detector head, which is indicated by the red
LED on the detector and the Alarm LED on the test station. Test
mode automatically times out after 20 seconds at which time the
detector returns to standby mode, regardless of the test station
keyswitch position.
8" (204 mm)
The optional Ground Level Test Station facilitates testing of a connected detector from safe and convenient location. The unit is key-operated with a two-position Test/Run switch and includes two dedicated
LEDs: one for Alarm indication and one for Power indication.
The ideal location and spacing of the Detector is critical in a properly installed and operating fire alarm system. It is recommended
that the detectors be located and spaced in accordance with the
National Fire Protection Association (NFPA) Standard 72 "The
National Fire Code". No liability will be accepted for applications
not conforming to NFPA regulations.

is numbered left to right. This diagram is an example for a single
reflective beam unit installed as the only device on a zone. The
correct operation for Fire and Trouble should always be verified.
Relays are shown in quiescent (standby) condition. Alarm and

Detector Installation
When installing the detector on a wall supported with wood studs,
ensure the fixing points are secured directly to the supporting
stud. When installing the detector on a wall supported with metal
studs, mount a metal plate at least 1/8" (3.2 mm) thick across two
studs and secure the detector to the plate.
