In this scenario, we would recommend this product which comes with a text pager. You can select multiple door sensors linked to one or more text pagers. Each door sensor can be programmed by us to display a unique message on the pager (e.g. room A, room B etc.). You can leave a note at the checkout to tell us which message you would like us to programme the door sensors to display on the pager.
Alternatively, you can purchase multiple door sensor/bleeper pager sets and we will put each set on a separate code. Please bear in mind that the bleeper pager won't display a message, so we will label the door sensor and bleeper pager with colour coded stickers so that you know which door sensor corresponds to which bleeper pager.
