  Let $ V_{n} = X_{1,n} + X_{2,n} + \cdots + X_{n,n}$ where $X_{i,n}$ are
Bernoulli random variables which take the value $1$ with probability $b(i;n)$.
Let $\lambda_{n} = \sum\limits_{i=1}^{n} b(i;n) $, $\lambda = \lim\limits_{n
\to \infty} \lambda_n,$ and $m_n = \max\limits_{1 \leq i \leq n} b(i;n)$. We
derive asymptotic results for $P(V_{n}=k)$ that hold without assuming that
$\lambda < +\infty$ or $m_n \to 0$. Also, we do not assume $k$ to be fixed, but
instead, our results hold uniformly for all $k$ which satisfy particular growth
conditions with respect to $n$. These results extend known Poisson local limit
theorems to the case when $\lambda = +\infty$. While our results apply to
triangular arrays, without the assumption that \(m_n \to 0\) they continue to
hold for sums of Bernoulli random variables. In this setting, our growth
conditions cover a range of values for $k$ not centered at $\lambda_n$, thus
complementing known local limit theorems based on approximation by the normal
distribution. In addition, we show that our local limit theorems apply to a
scheme of dependent random variables introduced in the work of Sevast'yanov.
