Before installing modules or making wiring connections to the panel, power down and unplug the transformer. For further guidance please refer to the D9412G/D7412G Program Entry Guide or Module Installation and Connection Guide respectively.
The D928 Dual Phone Line Switcher can be integrated into a panel to provide phone supervision services. Please refer to the D9412G/D7412G Programme Entry Guide for further guidance and instructions.
Security & Fire Detection
The D9412G control panel provides eight on-board points and up to 238 off-board points (depending on model and expansion interfaces), all programmable for burglar alarm, fire alarm or supervisory applications; assign an account number to define annunciation and control functions for individual points; group off-board points to create areas that can be individually or conditionally armed and controlled, or individually controlled and conditionally armed; schedule events (skeds) can also be set for execution at predetermined times for automatic function performance by predetermined times that perform a specific set function at predetermined times for automated system operation.
The panel’s on-board horn output provides up to 96 seconds of audio signaling. A keypad passcode activates Fire Test Mode, which suppresses reports to central station while permitting operator testing of each sensor independently. At the conclusion of testing, annunciator messages and keypad display indicate which sensors have not yet been checked – saving users from manually resetting sensors after every test run.
Perform a “sensor reset” at a command center to activate the verification/reset relay and avoid false alarms due to unsupervised tampering, while programming options for the verification/reset relays and points can be found in the D9412G/D7412G Operation & Installation Guide’s Program Entry Section.
Battery Monitoring
The D9412G/D7412G monitors the internal backup battery’s voltage level. If its voltage drops to 13.7 VDC or lower, an audible and visual indicator on the keypad illuminates. Depending on whether your system is configured for power supervision, your control panel could send out either a Battery Restore Report in Radionics‘ Modem IIIa Communication Format, or Trouble ZN 9 reports in BFSK format – with Low Battery LED lighting up as an extra warning that it is time to replace these batteries!
The D9412G/D7412G requires two A123 lithium batteries to function, with a keypad-mounted battery level LED providing feedback on current battery levels and each POPIT module having its own indicator LED to show whether arming or disarming is underway. You can easily manage battery levels using either a manual switch on the D8125 POPEX, or via its programmable keypad; each D8125 package also comes equipped with labels to mark their statuses.
Access Control
The control panel provides security and access control features. It can monitor alarm points for burglar and fire alarms, operate user command centers and other outputs, report to selected PSTN or IP network destinations through four programmable route groups and provide eight on-board points and up to 238 off-board points; its integrated access control functionality enables access through Wiegand style card readers connected to D9210B Access Control Interface Module, request-to-enter/exit input or keypad.
The panel can restrict access during armed periods by requiring valid codes to open door sensors, and restricting it based on whether the system is master armed, perimeter armed, disarmed or disarmed – even requiring valid user IDs in order to arm and disarm.
It has an integrated telephone monitoring function, with which it can switch to an alternate line in case of communication failure. When configured for two phone lines (Program 6.12.2), this switcher allows it to alternate between phones for sending its first report.
Finally, this panel has an inbuilt fire detector which can act both as a smoke and heat detector to quickly react to fire alarms. Furthermore, its built-in horn output may also be configured as an alert mechanism when activated by either smoke or heat alarms.
The panel contains a primary AC power circuit which provides 1.9 amps of rectified AC power, with 500 milliamps reserved for internal operations and leaving 1.4 amps for powered devices should AC power fail. If desired, one or more D8132 Modules (see Program Record Sheet) may be added to reduce current draw while not in alarm, having a 3.3 VDC, 500 mA battery back-up. Please refer to the Standby Battery and Current Rating Chart of D9412G/D7412G Approved Applications Compliance Guide for calculation of battery standby time calculations.
Power & Power Outputs
Primary AC power circuits supply 1.9 amps of rectified DC current to the panel for internal operations, leaving 1.4 amps for powered devices (Terminals 6 and 7). For maximum battery standby times refer to the current rating chart in the D9412G/D7412G Approved Applications Compliance Guide.
The system can communicate with up to eight command centers through its auxiliary output terminals, enabling devices at each command center to arm and disarm areas, report complete system status to control stations, initiate tests of various kinds and manage various other functions. Command center devices also report device trouble reports directly to panels while receiving signal back from them to report its state to control stations.
Relay A (Terminal 6) can be programmed for either steady alarm bell or pulsed fire bell output, Relay B (Terminal 7) can be programmed as either fire or smoke Verification/Reset Relays and Relay C (Terminal 8) as a smoke detector reset relay by default in most programs; for more details regarding programming verification/reset relays and points please refer to Relay Parameters and Point Assignments of D9412G/D7412G Program Entry Guide for complete instructions.
The D9412G/D7412G supports up to 246 off-board points using POPIT Modules, each of which requires one D8125 module for installation at their respective off-board point. Each POPIT module comes packaged with two sets of labels – keep one set aside for use with the D9412G/D7412G itself, while placing another set onto its base when connecting any off-board points.
Installation
The D9412G/D7412G Control/Communicator features two power outputs for connecting devices to its panel, with each output capable of receiving up to 1.4 amps from its power supply. Power is distributed to these outputs through terminal strips with voltage monitoring being conducted via an LED onboard the unit itself. If an output exceeds this limit or battery levels fall below an acceptable level, an LED will flash once every 30 seconds indicating either overage or low battery levels as well as when an alarm condition or relay activation.
Terminal strips connect up to 16 sensors per zone, each being assigned a unique point number and sending its transmission to the panel separately. This enables a variety of applications to be controlled from a single panel. When programming this system, users have the flexibility of assigning either single points to an OctoPOPIT or multiple points at once; when responding to commands these points send signals back out either to central station telephone lines or users’ telephone lines which in turn activate the fire alarm or sound an audible siren alarm.
Not only are power supplies used as power outputs, they can also act as emergency backup when coupled with a Radionics alarm transmitter connected to the panel. Should an alarm transmitter lose power, it will communicate with the panel and send out a status report; upon receipt, this report can activate an alarm which notifies monitoring companies over phone lines of any potential issues or issues that require attention – whether as simple TROUBLE ZN 9 report or more detailed SYSTEM ERROR ZN 9 message depending upon your programming options.
The D9412G/D7412G features multiple programming tools, such as the D5200 Programmer and Remote Account Manager, which can be found in its Program Entry Guide. Furthermore, its Literature Pack also includes a UL and Fire Approved Applications Compliance Guide, providing further guidelines for installing this control/communicator in applications approved for both UL and fire standards. A fire alarm system test should be performed periodically to verify all components are functioning as expected while maintaining compliance.
