Napco Security Technologies Inc. reported Monday its net income fell 12 percent for the most recent quarter, despite a modest increase in net sales.

The Amityville maker of electronic security, fire alarm and “connected home” devices for homes, businesses and schools had net income of $857,000 for the three months that ended Dec. 31, compared with $976,000 a year earlier.

Napco’s selling, general and administrative expenses for the quarter were $5.6 million, or 26.8 percent of sales. A year earlier, the company’s expenses were $5.2 million, or 25.3 percent of sales.

The company reported diluted earnings per share of 5 cents for the quarter, unchanged from a year earlier.

Napco’s stock price fell by 2.7 percent in midday trading, to $9.
