Det-Tronics X3300 Protect-IR Multispectrum IR Flame Detector - Manual (Page 15)

INSTALLATION USING Q9001L SWIVEL MOUNT
1. Install the swivel mounting bracket assembly on the
wall. The installation surface should be free of
vibration and suitable to receive 1/4 inch (M6)
screws with a length of at least 1 inch (25 MM).
2. Attach the detector/controller to the swivel mounting
bracket and tighten the 3/4 inch nut to secure it in
place. Refer to Figure 11 for dimensions of the
Q9001L swivel mount.
OPTICAL INTEGRITY ( oi)
AUTOMATIC oi
The X3300 includes the Automatic Optical Integrity ( oi)
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. A successful
automatic
oi test does not produce an alarm condition.
The Protect•ir signals a fault condition when less than
50% of the detection range remains. This is indicated
by the Fault relay and is evident by the amber color of
the LED on the face of the detector. See the
“Troubleshooting” section for further information.
MANUAL oi
The detector also incorporates a manual oi feature that
provides the same test as the automatic oi, and in
addition actuates the Alarm relay to verify output
operation. The manual
oi feature is available in all
models and can be performed at any time. This test
requires bypass of all extinguishing devices to avoid
release resulting from a successful test.
The manual oi test is activated by connecting the white
lead to power supply minus. This places the detector in
a special operating mode. First, the device de-latches
any latching outputs. Next, the IR emitters are activated.
If the resulting signals meet the test criteria, the Alarm
relay changes state and the indicating LED changes to
red. This condition remains until the white lead is
disconnected from dc minus. If the test criteria are not
met, no alarm is produced and no fault is generated.
See the “Troubleshooting” section for further details.
STARTUP PROCEDURE
When installation of the equipment is complete, perform
the “Fire Alarm Test” below.
Allow 20 to 30 minutes for the detector optics to reach
equilibrium. Housing will be warm to the touch.
FIRE ALARM TEST
1. Disable any extinguishing equipment that is
connected to the system.
2. Apply input power to the system.
