BM25_Area_Gas_Monitor2Oldham and a1-cbiss is very pleased to announce the launch of the exciting wireless version of the five-sensor transportable gas detector – the BM 25. As wireless capabilities reach new technological milestones, the integration of wireless gas detection systems in industrial applications is ever increasing.

The BM 25 Wireless brings you freedom and flexibility while keeping the standard characteristics of the BM 25:


  • Powerful audible alarm (103 dB @ 1m)
  • Ultra-bright flashing signal (viewable at 360°)
  • 1 to 5 gases simultaneously
  • Run time of up to 135 hours in Wireless version
  • Resistant to harsh environment
  • Easily transportable – less than 15 lbs
  • Up to 30 devices per network
  • Up to 16 independent networks
  • 2.4 GHz frequency
  • Up to 0.6 mile line-of-sight range


The network topology used by the BM 25 is a MESH network. In a mesh network all hosts are connected peer-to-peer without central hierarchy, thereby forming a net-like structure. Each node can receive, send and relay data and this avoids having sensitive points, which in case of failure, disrupts the connection of the network. If a node is down, it simply goes through another route. Mesh topology allows fast and simple deployment, high coverage versatility and high fault tolerance.

It significantly reduces installation and operating how to buy phentermine online no prescription costs of networks.

Adding a BM 25 on an existing network has never been so easy as you just need to turn it on. The

BM 25 is automatically added to the network.

If a BM 25 goes into gas alarm, all BM25s in the network will report a corresponding alarm. If a BM 25 does not respond to network communication requests, all other BM 25 units on the network will annunciate a communication fault error and let you know that one of its network member devices is not communicating. In all cases, the local gas detection capability remains effective and each BM 25 will provide local alarm capability in the presence of gas.


If the network is split due to an obstacle placed in the network, it is possible to continue to work as the network will automatically adjust and form two separate networks. When the obstacle is gone, the communication resumes automatically. The two groups merge together to form only one group again. Adding a new BM 25 to the network at a smart location also overcomes the obstacle
