New D7212G control panel with lithium battery. Includes faceplate shield, mounting skirt and one #6×1/4″ screw.
Areas
The D7212 can support up to eight individual zones, each with its own arming state and arming state modifier. Events and event modifiers related to each zone can be recorded and reviewed via D1255 Command Center, while local printing can be accomplished using D9131 Parallel Printer Interfaces.
Functions
The D7212 monitors AC power, battery charge level, ZONEX and SDI buses and CPU (Central Processing Unit). It oversees transformer connection at terminals 1 and 2, DC current rating of battery connected at terminal 8, checks that battery condition is good and disconnects it if there are shorted cells detected; this feature prevents excessive battery usage while prolonging its life span.
The CPU features a green LED to indicate if its system is powered on and transmitting alarm, trouble, and event log reports to command centers, keypads, D5200 programmer or any other devices connected by RJ31X telephone wire. When installing in environments where electromagnetic interference could be an issue it is advised to use shielded cables.
Connect up to six POPIT modules with eight relay outputs each to the D7212 using its flexible connector. Each POPIT module features five switches that select relay number. Their labels display their functions.
Areas and Accounts
The D7212 supports up to eight areas that you can arm and disarm using one menu function, assign points to an area or group of areas, then arm/disarm using individual menu functions for those points. Furthermore, events and their modifiers are recorded in a datalog which you can view via command center/keypad view, print using parallel printer interface with D1255 Command Centers, or upload into D5300 Remote Account Manager II systems.
The D7212 utilizes a battery-backed RJ31X telephone line to monitor its internal phone circuits, as well as dial four phones automatically in case of power outage or communication failure. Furthermore, it monitors signal strength of local telephone networks in order to identify any problems in its own network.
Troubleshooting
The D7212 monitors incoming phone line signals. If it detects that one of them has become off-hook, a communication failure report is sent directly to a remote monitoring station; additionally, local alarm and/or trouble reports are issued directly to SDI devices connected to it. A D8132 Battery Charger Module may be added for enhanced battery backup purposes – provided it’s powered from the same 120 VAC circuit as that which houses its transformer.
If a line goes off-hook, the CPU responds by sending a communication failure report to a remote monitoring station and also by activating D122A door/window contacts or detectors and sending an instruction to open or reset these devices; alternatively it may initiate alarm conditions (e.g. fire or burglary).
Faulty batteries may prevent your CPU from receiving instructions to activate its sensor loops or respond to alarm conditions. In cases where they cause shutdown of the CPU, shorted batteries must also be recharged or power down and power back on in order to reconnect their batteries and reconnect your panel.
If the system displays “COMM FAIL,” first make sure your control panel has access to its entire program. If not, load an updated one into D7212 and the display should go away.
Check that the D7212 is connected to a reliable ground reference, such as a rod or cold water pipe, as specified in its Program Entry Guide (74-0691 5-000). Referring to that guide will assist with programming verification and resets as necessary.
D7212 Sensor Loop Wiring The D7212 offers up to 32 on-board points for sensor loops and 40 off-board points as POPITs (Point of Protection Input Transponders). Onboard points are labeled 1-8; these sensor connections connect directly with your panel without needing an D8125 POPEX module.
Data wiring must be routed away from AC conductors and sensor loop wires, and should avoid fluorescent lights or electrical conductors in close proximity to your control panel.
Programming
The D7212 offers you a range of programmable functions. Please refer to the D7212 Program Entry Guide (74-06915-000) for full details on its capabilities. Before programming the panel, be sure to install any required accessory modules first and install all required accessory modules prior to power up or reset of your panel; The D7212 also performs self diagnostic tests at both powers up and reset – buzzers will sound during these self diagnostic checks.
The D7212 features on-board points that can be expanded with up to 40 POPIT modules, each of which can be assigned a unique number and programmed individually, offering many configuration options to tailor it specifically for your installation. On-board sensors include standard sensor loops; off-board POPIT modules each support eight points.
Points can be connected to power, ZONEX and SDI buses, keyboard, printer and two telephone lines. A CPU oversees AC power, battery charge level and two ZONEX busses while an alarm system supervisory circuit is protected by an inbuilt circuit breaker. Furthermore, D7212 also provides data outputs for annunciation purposes as well as power input for D125B powered loops, D129 class A loops or even the D8125 POPEX module.
Your phone company should install an RJ31X jack to connect the D7212 to a telephone network, supporting up to two wires of data and one RS232 port (used for external alarm panels). In addition, this D7212 comes equipped with its own terminal block for connecting directly with telephone networks.
If you only have one phone line, the D125B or D129 is ideal for adding additional zone output, key switches or line switchers to an existing line. Furthermore, each command center can oversee two lines simultaneously.
Before making any further connections to the D7212, make sure that Terminal 10 of your device is connected to earth ground via grounding rod or cold water pipe as an earth ground reference point.
The D7212 can send and receive alarm, trouble, event, supervisory, auxiliary and service reports to the D5200 programmer for display, editing and printing. A rest pin is included with each D7212 to reset its panel quickly while speeding communication with its programmer.
Installation
New in box D7212G control panel equipped with lithium battery. Includes installation instructions, documentation and miscellaneous hardware package.
The D7212 can monitor two telephone lines. You can assign each line one of four designations: primary, backup, secondary alarm or auxiliary alarm – each supporting different alarm events. In addition, you can configure the D7212 to display phone line monitor status on its system display or sound an alarm if its D128 phone line monitor module detects an anomaly; please refer to the D7212 Program Entry Guide (74-0691 5-000) for more details on these functions.
The D8129 OctoRelay module makes it possible to add eight relay outputs in eight groups to a D7212 computer, using five switches as relay numbers and accessing off-board points from point index, alarm memory or remote functions.
Addition of the D8129 gives your system additional remote programming capability, including sending custom alarm alert messages directly to command centers or alarm managers when an auxiliary alarm goes off. Furthermore, it enables accessing alarm memories or D5300 Remote Account Manager II so you can reset remote devices, send event log reports or alter other program parameters remotely.
The D1255 Alpha III Command Center provides complete system control and annunciation. You can connect up to eight command centers to one D7212 unit for maximum flexibility and an event log storage for each area, even if not sent out through D1255 or remote account managers.
Check the D7212’s shielded cable connections to ensure they are twisted and soldered properly, then use a continuity tester to ensure your loop is free from open, shorted, or foreign grounds.
Your D7212 should be tested weekly to ensure it’s operating optimally. Conduct a Fire Test (Command 58) and AC power test; these will help avoid false alarms due to power outages, transformer arcing or shorted batteries.
