Northern Airborne Technology TS100 - Manual (Page 14)

TS100/TS200 Series PA Speakers Manual SM70 Rev. 4.00
Do not operate the equipment with snow, water or other foreign matter in the
loudspeaker horn.
Do not clean the loudspeaker with compressed air.
Be careful only to operate the siren for 3 cycles at a time and trill for a short 2 to 3
second burst. The driver is unable to withstand constant signals – it requires a Duty
cycle (see above) to permit the unit to cool down.
2.3.3
Cabling and Wiring
All unshielded wire shall be selected in accordance with AC43.13-1B Change 1,
Paragraphs 11-76 through 11-78. Wire types should be to MIL-W-22759 as specified in
AC43.13-1B Change 1, Paragraphs 11-85, 11-86, and listed in Table 11-11.
For shielded wire applications, use Tefzel MIL-M-27500 or MIL-M-81044 shielded wire
with solder sleeves (for shield terminations) to make the most compact and easily
terminated interconnect. Follow the wiring diagrams in Section 2.5 as required.
2.3.4 Mechanical Installation
The installing agency is responsible for the design, engineering and installation of the
mounting bracket for the Speaker. Careful consideration should be given to the
operating environment and the mechanical forces acting upon the unit.
When installing the speakers, ensure that there is adequate airflow to cool the
speaker drivers, and that the speaker phasing is correct.
Note: The speakers are designed for intermittent operation only.
CAUTION
Failure to install the TS200WR speakers as shown in the
relevant wiring diagram(s) will result in PERMANENT AND
IRREPARABLE DAMAGE to the speaker drivers.
Both speaker drivers MUST be wired in phase to ensure
proper performance and to prevent damage.
