In Keltron’s active radio network system, the RF7300 radio network controller serves as the system’s communications interface to the DMP703/704 alarm monitoring system. The 97P0065 software module provides the serial port personality and system functionality for the management of all data transmitted from the radio network through the RF7300 to the DMP703/704. NET 7K software running on a customer-supplied PC can connect to the RF7300 providing network status information and remote transceiver programming.
Keltron’s versatile DMP703/704 alarm monitoring systems enable capabilities for interfacing, integrating, monitoring and automating alarms and alarm management. The DMP703/704 alarm monitoring system simultaneously provides an intuitive operator interface and monitors direct connects, DACTs, private or distributed-multiplex inputs, coded fire alarm signals, DACRs, other systems, and networked radio signals.
These capabilities are now complemented by the agility of the smart routing radio alarm-monitoring network. This very powerful combination can be seamlessly applied to municipal, educational, industrial, proprietary, commercial, and military situations.

How it works
The radio network consists of subscriber radio transceivers positioned to provide multiple paths to the monitoring location for each monitored location that uses a subscriber radio transceiver. At the monitoring location are the RF7300(s) and the DMP703/704(s). The RF7300 and the DMP703/4 interface use contact-ID protocol that is transmitted using dynamically supervised RS232. This system supports both hot and cold redundant DMP703/704 configurations as well as cold redundant RF7300s. Both the active and stand-by RF7300 units are supervised for operability.
Programming the DMP703/704 message database may be easily duplicated between accounts and only light programming is required to activate account supervision and go online. Minimum field programming is required, as pre-defined contact-ID event code default descriptors are annunciated according to the reporting priority and printout color defaults.
Event restorals automatically remove the corresponding activations from the rotating display.
Sequential duplicate signal suppression software is included to ensure that any signal transmitted by the network and repeatedly passed on by the RF7300, is annunciated only once by the DMP703/704.
The network controller communicates with all subscriber transceivers periodically and test or check-in signals are managed by theDMP703/704 without operator involvement. Check-in failures are annunciated immediately upon timer expiration. All network and system communications are supervised and the integrity of all data is verified and compatibility with DMP703/4 system utilities such as remote programming DMP703/704 is preserved.
Radio alarms are presented in standard digital alarm communicators reporting format. The programmable account, zone, and event code fields are supported along with the time and date stamp fields and field identifiers.
Additionally, the DMP703/4 will report messages indicating the status of the radio network and controller. These may be used for diagnostic purposes and include reports such as loss of subscriber radio communications.
Applications requiring automatic system response to specific customer selectable events are easily accommodated by the vast array of available DMP703/4 system hardware and software outputs. These include interfaces to third party equipment such as pocket pager notification systems and remote annunciators.
Notification of local, remote, stationary or mobile responders to possible dangerous situations and their locations can be done expeditiously.
It is straightforward and cost-effective to add the capability of monitoring alarms with the RF7300 to an existing DMP703/4.
A software upgrade with plug-in hardware and the proper interfacing connectors are needed.
All software upgrades to existing systems are developed from the current standard release version of source code. This includes the latest enhancements and customer requested changes that will enhance the operation of your monitoring center. Standard release versions that are debugged and tested prior to release and then archived, ensure Keltron’s ability to provide ongoing support.
Upgrades require the 97P0065 software module and the standard 95K3068-5, dual port, isolated, RS232 interface assembly and memory cards. Non-volatile memory cards are available for multiple functions such as automatic event-specific message annunciation or account supervision status. They also support retention and reactivation of rotating off-normal-event displays after reset or power loss situations.
The radio network interface software provides a buffer for more than 1500 received events to ensure receipt of all signals even during periods of peak activity. A touch screen display rotation buffer of 500 off-normal events is also standard.
A PC is not a critical component of the Keltron RF7300 based radio network, however it facilitates diagnostic tasks and installation. The RF7300 provides the interface to ensure that failure of the attached PC does not affect overall network operation or the functioning of the DMP703/704. The system uses standard DMP703/704 hardware to achieve commonality of spare parts for all installations and the RF7830 central transceiver shares common components with the subscriber transceivers, reducing spare inventory requirements.
