BFM2M Possible Wiring diagram Boiler, Freezer or other Machine Monitor Machine Output by connecting to BFM2M input. Remember BFM2M Inputs are positive in nature so pulling down will trigger. Mobile Network Signal Strength. Reset device Or Power Cycle BFM2M Output. Volt free contacts 1. On Steady: Strong Signal N/O COM N/C BFM2M PCB 2. Flashing: Acceptable Signal. 3. Off: No Signal. Insert SIM Card Here Network Registered. 1. Flash every Second : Not Registered 2. Flash Every 3 Seconds : Registered Signal Strength Antenna Connector BFM2M Power Connector Power Registered BFM2M Inputs - + PIR Wiring. 1. The PIR must be powered by connecting to 12V + and – on the PIR PCB I/P I/P I/P I/P 1 2 3 4 Power Supply PIR + Positive 12V to PIR +12V DC - Ground line to PIR 2. Next the PIR output must be wired to one of the BFM2M Inputs. Diagram shows wired to Input 1. 3. The BFM2M has pull down inputs(negative polarity), but some PIRs operate opposite to this. In this case change the inputs for positive polarity by sending the command SMS text positive input x where x is the input the PIR is wired to.
