The Universal Multi-Input Transmitter for MPPL Alarms is a replacement transmitter for the Door And Window Contact Alarm With Pager Kit and others. It enables you to monitor the status of windows and doors in your home.
The transmitter is powered by a 9V battery which is included unattached, saving energy. It has a range of 100 metres and features a low battery warning that is transmitted to the pager (not included). The transmitter's battery will last up to 12 months depending on the battery used.
The LED is illuminated when transmitting a signal, and an optional power saving mode can be activated which turns the LED off, adding an additional 6 months to the battery life.
Arrows on the transmitter show where the magnet (not included) should be placed, and the magnet has a range of 1cm, giving you even more flexibility in placing.
The dimensions of the transmitter are 137mm x 38mm x 22mm.
