The Resideo (5140DLM) is a back-up phone line dialer module for commercial Ademco fire panels. First, it adds a second supervised dialer output to the host panel. Then, it keeps central-station reporting alive if the primary dialer is taken out of service.
Resideo (5140DLM) Back-Up Dialer Module
The 5140DLM is purpose-built for the Ademco commercial fire panel family. For example, it pairs with the VISTA-128FBP, VISTA-250FBP, and VISTA-32FB control panels. As a result, the host panel can fail over to the secondary phone line automatically.
Key Features
- Supervised secondary dialer output — independent of the primary dialer on the host panel
- Green LED indicator — shows when the module is actively seizing the phone line
- Module sub-assembly — mounts inside the commercial Ademco enclosure
Compatibility
The 5140DLM is designed specifically for Honeywell/Ademco commercial fire panels. In addition, it requires a host panel that publishes a 5140-series dialer interface. However, the 5140DLM does not function as a standalone dialer — it is a back-up only.
Ordering the Resideo (5140DLM)
Life Safety Consultants stocks the 5140DLM module. Therefore, technicians servicing VISTA-128FBP, VISTA-250FBP, or VISTA-32FB jobs can usually get replacement units the same day. Furthermore, our sales team can confirm panel firmware compatibility before shipment.
