Det-Tronics X3302 Multispectrum IR Flame Detector with Pulse Output - Manual (Page 9)

Detector Wiring
Important
If installing an X3302 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 X3302.
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 X3302 Flame 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 X3302 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.
