71033 Datasheet, PDF (1/3 Pages) Gamewell-FCI by Honeywell – Conventional Two-Wire Smoke Detectors
Series 60
Description
The Gamewell Series 60 Conventional Smoke Detectors
are comprised of ionization, photoelectric, combination
photo/heat, and rate-of-rise/fixed-temperature thermal
detectors (135°F, 160°F, 210°F [57.2°C, 71.1°C, 98.8°C]).
These detectors are carefully designed and rigorously
tested to ensure that they meet all standards, codes and
the demands of today’s environments.
The detectors are designed for two-wire operation. All the
detectors in the Series 60 product line have the same
external dimensions. The housing of the ionization and
photoelectric detectors is identical. The external alarm indi-
cator is a light-emitting (red) diode (LED) which is clearly
visible. The ion detector is distinguished from the photo-
electric detector by the color of the alarm indicating LED.
The ion's LED is red while the photoelectric’s LED is clear
during normal operation. Thermal detectors are readily dis-
tinguished from smoke detectors by open webs that allow
the free movement of air around the exposed thermistor.
Operation
The Gamewell 71034 ionization smoke detector operates
on the ionization principle using twin compensating cham-
bers with one single-sided ionizing radiation source. The
ionization chamber system is a reference chamber con-
tained inside an outer smoke chamber. The outer smoke
chamber has smoke inlets, which are fitted with an insect
resistant mesh. At the junction between the reference and
smoke chambers is the sensing electrode which converts
variations in the chamber currents to a voltage. This volt-
age produces a signal which latches the detector into
alarm when a preset threshold level is reached.
The Gamewell 71033 photoelectric smoke detector oper-
ates on the forward light-scattering principle. It uses a hori-
zontal optical bench which houses an infrared emitter and
sensor arranged radially to detect forward scattered light.
The sensing chamber is a black molding configured as a
labyrinth, which prevents ambient light from penetrating the
chamber. The labyrinth has a fine gauze cover to prevent
insects from migrating into the chamber. The detector will
change to the alarm state when reflected light is of suffi-
cient amplitude to turn on the SCR that sends the alarm
signal.
