SP-20M Wireless door sensor<\/h1>\n

[\/vc_column_text][vc_column_text][\/vc_column_text][vc_empty_space height=”30px”][vc_column_text]The SP-20M is intended to be used in conjunction with activity monitoring operations managed by TeleAlarm Carephones or for transmission of specific events.<\/p>\n

The SP-20M can be activated by the movement of a magnet, or by the opening of an electrical contact. When the top housing is removed, a tamper switch detects this event, which is then transmitted to the Carephone.[\/vc_column_text][vc_empty_space height=”20px”][\/vc_column][vc_column css=”.vc_custom_1581998548471{margin-top: 0px !important;margin-right: 0px !important;margin-bottom: 0px !important;margin-left: 0px !important;border-top-width: 0px !important;border-right-width: 0px !important;border-bottom-width: 0px !important;border-left-width: 0px !important;padding-top: 0px !important;padding-right: 0px !important;padding-bottom: 0px !important;padding-left: 0px !important;}” offset=”vc_col-lg-offset-1 vc_col-lg-6 vc_col-md-offset-0 vc_col-md-6 vc_hidden-sm vc_hidden-xs”][vc_single_image image=”57992″ img_size=”full” css=”.vc_custom_1633939871354{margin-top: 12% !important;margin-bottom: 0% !important;padding-left: 50px !important;}”][\/vc_column][\/vc_row][vc_row equal_height=”yes” content_placement=”bottom” el_id=”characteristics”][vc_column]
