Car Alarms: nissan primastar van alarm, nissan primastar, power spike

Question
could the hot weather be causing my alarm to sound at night?

Answer
Sure. It depends on how hot, but yes,
sensors can be affected by high and low temps.

It would then trigger the alarm.

Also check the battery as this is how
the alarm reports. When a perceptable
battery power spike is "seen", the alarm
sounds.
