Specifications

95-8554211. 1
The Auxiliary relay has normally open / normally
closed contacts, and is configurable for energized or
de-energized operation, and latching or non-latching
operation.
0 to 20 mA Output
A 0 to 20 mA output is available as an option (in addition
to the three relays). This option provides a 0 to 20 mA dc
current output for transmitting detector status information
to other devices. The circuit can be wired in either an
isolated or non-isolated configuration and can drive
a maximum loop resistance of 500 ohms from 18 to
19.9 Vdc and 600 ohms from 20 to 30 Vdc. Table 1
indicates the detector status conditions represented by
the various current levels. The output is calibrated at the
factory, with no need for field calibration. A model with
relays and 0-20 mA with HART is also available. Refer to
Addendum number 95-8637 for complete details.
NOTE
The output of the 0 to 20 mA current loop is not
monitored by the fault detection circuitry of the
X9800. Therefore, an open circuit on the loop will
not cause the fault relay to change state or the
detector status LED to indicate a fault. The status of
the LED always follows the status of the relays.
An alarm condition will normally over-ride a fault
condition, unless the nature of the fault condition
impairs the ability of the detector to generate or
maintain an alarm output, i.e. loss of operating power.
LON/SLC Output
The EQP model is designed for use exclusively with
Det-Tronics' Eagle Quantum Premier system. The
detector communicates with the system controller over
a digital communication network or LON/SLC (Local
Operating Network / Signaling Line Circuit). The LON/
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.
LED
A tri-color LED on the detector faceplate indicates
normal condition and notifies personnel of fire alarm or
fault conditions. Table 2 indicates the condition of the
LED for each status.

Automatic o
i
The X9800 includes the Automatic o
i
feature — a
calibrated performance test that is automatically
performed once per minute to verify complete detector
operation capabilities. No testing with an external test
lamp is required. The detector automatically performs
the same test that a maintenance person with a test
lamp would perform — once every minute, 60 times per
hour. However, a successful Automatic o
i
test does not
produce an alarm condition.
The X9800 signals a fault condition when less than half
of the detection range remains. This is indicated by the
Fault output and is evident by the yellow color of the LED
on the face of the detector. See the "Troubleshooting"
section for further information.
Magnetic o
i
/ Manual o
i
The detector also incorporates both Magnetic o
i
(Mag o
i
) and Manual o
i
(Man o
i
) features that provide
the same calibrated test as the Automatic o
i
, and in
addition actuates the Alarm output to verify operation
for preventive maintenance requirements. These
features can be performed at any time and eliminate
the need for testing with a non-calibrated external test
lamp.
