  The HTRU-S Low Latitude survey data within 1$^{\circ}$of the Galactic Centre
(GC) were searched for pulsars using the Fast Folding Algorithm (FFA). Unlike
traditional Fast Fourier Transform (FFT) pipelines, the FFA optimally folds the
data for all possible periods over a given range, which is particularly
advantageous for pulsars with low-duty cycle. For the first time, a search over
acceleration was included in the FFA to improve its sensitivity to binary
pulsars. The steps in dispersion measure (DM) and acceleration were optimised,
resulting in a reduction of the number of trials by 86 per cent. This was
achieved over a search period range from 0.6-s to 432-s, i.e. 10 per cent of
the observation time (4320s), with a maximum DM of 4000 pc cm$^{-3}$ and an
acceleration range of $\pm 128$m s$^{-2}$. The search resulted in the
re-detections of four known pulsars, including a pulsar which was missed in
previous FFT processing of this survey. This result indicates that the FFA
pipeline is more sensitive than the FFT pipeline used in the previous
processing of the survey within our parameter range. Additionally, we
discovered a 1.89-s pulsar, PSR J1746-2829, with a large DM, located~0.5 from
the GC. Follow-up observations revealed that this pulsar has a relatively flat
spectrum($\alpha=-0.9\pm0.1$) and has a period derivative of
$\sim1.3\times10^{-12}$ s s$^{-1}$, implying a surface magnetic field of
$\sim5.2\times10^{13}$ G and a characteristic age of $\sim23000$ yr. While the
period, spectral index, and surface magnetic field strength are similar to many
radio magnetars, other characteristics such as high linear polarization are
absent.
