SAFETY MESSAGES
Procedures and instructions in this section may
require special precautions to ensure the safety of
personnel performing the operations. Information that
raises potential safety issues is indicated by the word
“Warning”. Always read and understand these safety
messages.
WARNING
The X3301/X3302 is intended for use in hazardous
environments that may include explosive levels of
flammable gases and vapors. This product must
be properly installed, operated and maintained.
Improper installation or use could result in an
explosion or fire resulting in death or serious
injury.
• Do not remove the detector cover in explosive
environments when device power is on and
circuits are live.
• Detector must be properly installed, and wiring
compartment cover must be fully engaged
to meet hazardous area explosion-proof/
nonincendive requirements.
DESIGN
The X3301/X3302 is an infrared flame detector that
is classified as a Type B smart device according to
IEC61508. The standard model provides an isolated
4‑wire, 0‑20 mA output, together with on‑board Alarm
and Fault relay contacts. These outputs serve to
indicate normal operating condition of the detector,
fault, or the presence of a flame alarm. The X3301/
X3302 contains extensive self‑diagnostics and is
programmed to send the current output to a specified
state (1 mA, 2 mA or 3 mA) upon internal detection of a
failure or fault condition.
HART communication is available as an option. The
HART option allows the operator to monitor the status
of the detector, determine factory settings, adjust
field settings, and initiate field tests. For complete
information regarding HART communication, refer to
the appropriate HART Addendum:
X3301 95‑8577
X3302 95‑8613
When using the 0‑20 mA output with HART as a safety
output, it is required that Write Protect be set to “on” to
ensure that the HART is non‑interfering.
NOTE
All configuration changes to the X3301/X3302
must be verified by the user via a proof test,
power cycle and re-check of settings, or other
appropriate method.
The EQP model is designed for use exclusively with
the Det‑Tronics Eagle Quantum Premier system. The
detector communicates with the system controller
over a digital communication network or EQPSL/SLC
(Eagle Quantum Premier Safety Loop / Signalling
Line Circuit). The EQPSL/SLC is a fault tolerant, two
wire digital communication network arranged in a
loop configuration. Analog and relay outputs are not
available on this model. For information regarding the
use of the SIL 2 Certified X3301 in an EQP system, refer
to the EQP Safety Manual 95‑8599.
The X3301 is designed for operation with a supply
voltage from 18‑30 volts DC. Proper operation outside
this range cannot be assumed.
Safety‑Certification of the X3301/X3302 includes:
• Analog Output
• Relay Output
• EQP LON Output version for X3301 only
• HART Output as non-interfering
• xWatch Surveillance Camera output as non-
interfering*
Safety‑Certification of the X3301/X3302 does not
include:
• Pulse Output
• RS-485 Modbus signal
• EQP LON Output version for X3302
* The xWatch Surveillance Camera has been evaluated
as a non‑interfering device and is approved for use
with a Safety‑Certified X3301/X3302. The xWatch
camera can be attached directly to the X3301/
X3302 through a factory installed integral connection
adapter. The addition of the xWatch does not affect
the safety performance of the X3301/X3302. Refer
to manual number 95‑8603 for details regarding the
xWatch camera.
