We have a Texecom Premier Elite 64W with a Premier LCDLP-W Wireless Keypad. Over the past few days, a tamper has been activating, seemingly out of the blue and attributable to this wireless keypad rather than any of the sensors. How do we ascertain what's causing the wireless keypad to raise an alert that it's been tampered with so that we can address the issue? The batteries are okay, according to Wintex.
