Keltron's DMP703/704 alarm monitoring system is highly flexible, able to receive signals from a wide range of devices on site at protected properties. We offer a range of options that solve a variety of scalability, location and budget concerns.
Signal transmissions via both wire and fiber optics
Keltron's compact Tones transmitters convert DC signals to tones, enabling signal transmission via fiber optics. Easily installed in alarm control panels, they may also be mounted separately to ensure reliable alarm transmission Telco installation of fiber optic lines precludes direct transmission of voltages.

Data gathering panels
Data gathering panels (DGPs) enable data transmission from up to 32 fully supervised zones. A DGP receives alarm signals and relays them via a single or dual communication link (twisted pair or normal voice-grade Telco line) back to the central signaling unit (CSU) at the monitoring site. This method saves wiring costs and creates a reliable, multiplexed alarm monitoring system.

Distributed multiplex transceivers
Keltron's partyline event transceivers (PETs) provide reliable, low-cost protection of proprietary, commercial and industrial buildings. UL-listed and NFPA-72 compliant, Keltron PET Series transceivers enable high-performance error-detection during serial, multiplexed signal transmission and retransmit contact status on the serial data output from an FACP with cost-saving wiring flexibility.

AA-grade security transmitters
A high line security, UL-listed AA transmitter (AATM) that accepts two RP inputs is match-paired with an AA grade receiver module (AARM) at the monitoring station. This system, compatible with fiber optic transmission paths, incorporates the encoding/decoding required for AA-grade secure transmission.
