Det-Tronics X3301 Multispectrum IR Flame Detector with Pulse Output - Manual (Page 9)

7 95-8528 11.1
Detector Wiring
Important
If installing an X3301 in place of an existing
detector, be sure to move the “A” Lead (detector
power) at the controller from the +290 Vdc source
to the +24 Vdc source.
Do not apply 290 Vdc to
the X3301.
1. Make field connections following local ordinances
and guidelines in this manual.
Figure 4 shows the wiring terminal strip located
inside the detector’s integral junction box.
Figure 5 shows the wiring terminal identification for
the X3301 detector with pulse output.
Leave the shield open at the detector end and
permanently isolate it from accidental contact with
the case and/or other conductors. At the controller/
fire panel end, connect the shield and power minus
(–) to chassis (earth) ground either directly or
through a 0.47 µF 400 Volt non-polarized capacitor
(not supplied). (Refer to Figures 6 through 10.)
Figures 11 and 12 provide examples of typical
installations with a X3301 wired to a fire alarm
panel.
Figure 13 shows an EOL resistor installed within the
integral wiring compartment of the detector (refer to
“EOL Resistors” for details).
2. Check all field wiring to be sure that the proper
connections have been made.
Important
Do not test any wiring connected to the detector
with a meg-ohmmeter. Disconnect wiring at
the detector before checking system wiring for
continuity.
3. Make the final sighting adjustments and use a 14 mm
hex wrench to ensure that the mounting arm assembly
is tight.
