Description
About this model
LRMAB — Alert Monitor for Open Door DC with Buzzer.
The LRMAG, LRMAF, LRMAC, LRMAD, LRMAB, LRMAT and LRMAS alert monitors were developed to facilitate installation, maintenance, and layout changes.
Using two AA alkaline batteries as power source, with autonomy of 12 to 24 months (depending on the number of tests and activations), with wireless communication radio with operating frequency of 915 MHz or 2.4 GHz and ISM band, it has never been so easy and fast to install alert monitors.
