Introduction

Protective Points

As shipped, the Radionics D9124 Addressable 24 VDC System provides eight on-board

points built into the panel. On-board points 7 and 8 support a 24 volt power supply and

notification circuits, and are not for other uses. As shipped, the panel can support 63 added

POPITs. In addition, if you use an additional D8125 POPEX Module, another 63 points can

be added, for a maximum total of 134 (8+63+63). Each point requires an addressable

device for individual annunciation, such as the D462, D290S, D290M, or a POPIT. Each

point is programmed separately with options to custom-fit the protection to your installation.

Point programming parameters determine the system’s response to open and shorted

conditions on the sensor loop.

Communicator

The D9124 Addressable 24 VDC System uses a built-in digital communicator to send

reports to the receiver. Up to four receiver phone numbers can be programmed. You can

program the panel to send reports to primary, backup, and duplicate phone destinations.

The panel transmits reports in either Modem or BFSK format. It is recommended that you

use the Modem format to provide full system information to the receiver.

The D9124 System connects to two D166 RJ31X (or RJ38X) jacks for phone line seizure.

Connection to the jacks complies with FCC regulations for using the public telephone

network. The D9124 System uses the built-in D928 Dual Phone Line Switcher to supervise

two phone lines.

24 Volt DC Outputs

The D9124 Control Communicator provides a 24 volt DC power supply. This power supply

is rated at 4 amps. The operating voltage range of this output is from 18.9 VDC to 28 VDC.

All Radionics 24 volt indicating devices are compatible with this power supply. For other

indicating and initiating devices refer to the manufacturer’s installation instructions and verify

the devices minimum operating voltage is equal to or less than 18.9 volts DC and the

maximum operating voltage is equal to or greater than 28 volts DC.

Important: Connection of 24 volt indicating and initiating devices that have a

minimum operating voltage greater than 18.9 VDC or a maximum operating voltage

less than 28 volts DC may be damaged or fail to operate!

Time and Date

To set the time and date you need a D1255 Command Center or RAM II.

Event Logger

The D9124 System stores up to 500 system events and event modifiers in its Event log.

Event modifiers add information about an event to the log. Some events are always followed

by a modifier. For example, the D9124 System adds at least two items to the log each time

it reports a phone line failure or keypad failure. It sends the event name and then an event

modifier showing the number of the failed device.

All events and their modifiers are stored even if the D9124 System does not send a report

for them. You can view the log at a D1256 Fire Command Center, print it locally using the

D9131 Parallel Printer Interface and a parallel printer, or upload it to a D5300 Remote

Account Manager II (RAM II).
