December 22, 2000 The modifications between the currently listed WLS912-433 and the new model for submission are as follows: For Lithium Glass Break, PIC chip is used as µprocessor instead of Zilog. This change will reduce idle current from 8-9µA to 4-5µA and allow the minimum operating voltage to drop down to 2.5Volts. Correspondingly, battery circuits can be redesigned to two 3Volts lithium battery in parallel to increase the battery life.
