Sewer Alarm Receiver (med)


Practical, visually appealing, and tough industrial/commercial rated 4-zone wireless Blocked Sewer and High-Level Sump Alarm with a Proven History in the Utility, Industrial, Commercial, and Healthcare (NHS) Sectors.

Designed to compliment the simplicity of our BDT Blocked Sewer and Sump Alarm Transmitters, the Sewer Sentinel Receiver is housed in a wall-mounting stainless steel enclosure that can be easily surface mounted onto virtually any wall finish.

Easy to install, the Sentinel receiver is supplied pre-programmed to accept messages from up to 4 of our BDT Blocked Sewer Alarm Transmitters, where each transmitter is assigned to a zone that simply displays Green when the sewer level is normal and Red once the sewer level has risen beyond the trigger point.  Zones can be allocated by the installer to monitor sewers, drains, gullies and sumps.
