Det-Tronics X3301 Multispectrum IR Flame Detector SAFETY MANUAL - Manual (Page 3)

5.1 95-8582 3
VALID INPUT RANGE
X3301/X3302 fault annunciation is provided on the
0‑20 mA signal output loop by signaling to a 1 mA, 2
mA, or 3 mA current output level. The receiving device
must be programmed to indicate a fault condition
when current levels reach over‑current (≥ 21 mA) or
undercurrent (≤ 3.6 mA).
DIAGNOSTIC RESPONSE TIME
NOTE
The X3301/X3302 analog signal and relay outputs
are not safety-rated during detector warm-up or
signal output loop testing (including proof testing).
Alternative means should be used at the job site
to ensure facility safety during these activities.
The X3301/X3302 will perform all critical diagnostic
functions within 58 minutes, worst case diagnostic
detection time. The user must not configure the
automatic oi test interval and failure annunciation count
combination to be greater than 58 minutes (default
setting is one minute intervals, with failure annunciation
after three failed oi tests).
OPTICAL INTEGRITY TEST
The oi test is designed to generate a fault when the
unit’s detection range has been reduced by 50% or
more. This factor should be carefully considered
during detector placement with regard to the required
safety function.
CERTIFICATION
The X3301/X3302 Safety‑Certified version is certified to
IEC61508:2010 for single input use in low demand SIL
2 Safety Instrumented Systems.
SAFETY-CERTIFIED PRODUCT IDENTIFICATION
Safety Certification of all X3301/X3302 models meeting
SIL 2 safety standards is clearly identified on the
product label.
INSTALLATION
NOTE
For complete information regarding performance,
installation, operation, maintenance and
specifications, refer to the appropriate instruction
manual:
X3301 95-8527
X3302 95-8576
Tools Required:
• 14 mm hexagonal wrench
No special installation requirements exist above and
beyond the standard installation practices documented
in the instruction manual. Environmental specification
limits are also as published in the general specifications
section in the instruction manual.
The operating power distribution system must be
designed and installed so the terminal voltage does
not drop below 18 Vdc when measured at any specific
location. The maximum current limit must be less than
2 amperes. The external system providing power to
the X3301/X3302 must have overvoltage protection that
ensures supply voltage does not exceed 33 Vdc.
