How do I install the control panel into the enclosure?
1. Place the control panel over the inside back of the enclosure, aligning the large rectangular openings of the mounting skirt with the mounting hooks of the enclosure. Slide the control panel down so that it hangs on the hooks.
2. Remove the tape from the #6 x 1/4-in. screw in the mounting tab on the control panel. The screw passes through the mounting tab and into the skirt mounting hole in the enclosure. Tighten the screw to secure the control panel in the enclosure.
3. Connect earth ground to the control panel before making any other connections.
How do I connect the earth ground?
To help prevent damage from electrostatic charges or other transient electrical surges, connect the system to earth ground at Terminal 10 before making other connections. Recommended earth ground references are a grounding rod or a cold water pipe.
WARNING! Do not use telephone or electrical ground for the earth ground connection. Use 1.8 mm (14 AWG) to 1.5 mm (16 AWG) wire when making the connection. Do not connect other control panel terminals to earth ground.
How do I enable and use the Ground Fault Detect feature?
To meet UL 864 requirements, enable Ground Fault Detect.
A ground fault is a circuit impedance to earth ground. The control panel has a ground fault detection circuit that, when enabled, detects ground faults on Terminals 1 to 9 and 11 to 32. The control panel also detects and annunciates ground faults on any device connected to it. If a ground fault condition occurs, the keypads display SERVC GND FAULT and the control panel sends a GROUND FAULT TROUBLE, AREA 1. When the control panel recognizes that the ground fault condition is corrected, and remains corrected for between 5 to 45 consecutive seconds, a Restoral Report is sent.
To enable the Ground Fault Detect Enable feature, lock (close) the S4 Ground Fault Detect Pin on the control panel.
| Callout | Description |
|---|---|
| 1 | S4 Locked (Closed). Control panels detects ground faults. |
| 2 | S4 Unlocked (Open). Control panel does not detect ground faults. |
What are the ground fault impedance specifications for the D7212GV3?
| Impedance | Control Panel Detects Ground Fault |
|---|---|
| ≤ 300 Ω | Yes |
| 300 Ω to 200 k Ω | Detection depends upon the terminal |
| > 200 kΩ | No |
How does locking the Reset Pin affect the control panel?
Locking the reset pin disables the control panel. When the control panel is disabled, the system ignores the keypads and points. CALL FOR SERVICE appears in keypad displays when the pin is locked down.
On-board relays (Terminals 6 and 7) and off-board relays deactivate when the control panel is reset. Terminal 8 has power when the relay is deactivated. Activation interrupts power at that terminal. The on-board relay (Terminal 8) remains deactivated when the reset pin is locked in the disable position.
Releasing the reset pin from the closed position resets the control panel. The control panel resets all its timers, counters, indexes, and buffers. Any points that restore after a reset do not generate Restoral Reports.
Locking the pin in the disable position applies power to the control panel and charges the battery while the detection devices and keypads are installed.

How do I install the transformer?
NOTICE! Do not short-circuit the terminals of the transformer. Shorting the terminals opens the internal fuse, causing permanent failure. Connect the transformer to Terminals 1 and 2 of the control panel before plugging it into the power source.
NOTICE! Always connect the battery first and then plug in the transformer.
1. Use 1.22 mm (18 AWG) wire (minimum) to connect the transformer to the control panel. The wire length should be as short as possible. The maximum length is 15 m (50 ft). Connect the battery and plug in the transformer.
2. Route telephone and sensor loop wiring away from any AC conductors, including the transformer wire. AC wiring can induce noise and low level voltage into adjacent wiring. Route data wiring away from AC and telephone wiring.
3. Connect the battery.
4. Plug the transformer into an unswitched, 120 VAC 60 Hz power outlet only.
5. Secure the transformer to the outlet with the screw provided.
Use the D8004 Transformer Enclosure for the D1640 Transformer in fire and combined fire and burglary applications.
How do I install the battery?
WARNING! Use Lead Acid Batteries Only: The charging circuit is calibrated for lead-acid batteries. Do not use gel-cell or nicad batteries.
1. Place the battery upright in the base of the enclosure.
2. Locate the red and black leads supplied in the literature pack.
3. Connect the black battery lead to Terminal 4, and then to the negative (-) side of the battery.
4. Connect the red battery lead to Terminal 5, and then to the positive (+) side of the battery.
WARNING! High current arcs are possible. The positive (red) battery lead and Terminal 5 can create high current arcs if shorted to other terminals or the enclosure. Use caution when working with the positive lead and Terminal 5. Always disconnect the positive (red) lead from the battery before removing it from Terminal 5.
WARNING! The battery terminals and wire are not power limited. A 6.4 mm (0.250 in.) space must be maintained between the battery terminals, battery wiring, and all other wiring. Battery wiring cannot share the same conduit, conduit fittings, or conduit knock-outs with other wiring.
How can I increase battery back-up time?
To increase battery back-up time, connect a second 12 V battery in parallel to the first battery. Use a D122 Dual Battery Harness to ensure proper and safe connection.
The D1218 is a 12 V, 18 Ah battery for use in applications requiring extended battery standby time. Up to two D1218 batteries can be connected when used with a D122 Dual Battery Harness.
WARNING! When connecting two D1218 Batteries to the control panel, both must have the same capacity (use two 17.2 Ah batteries or two 18 Ah batteries).
NOTICE! When using two D1218 batteries, use a separate enclosure, a D122L Dual Battery Harness, and long leads.
How are the power outputs protected from short circuits?
Three self-resetting circuit breakers protect the control panel from short circuits on the continuous and programmable power outputs. If the control panel is programmed for power supervision and a short circuit occurs on one of the power outputs, the control panel sends a BATTERY LOW or BATTERY MISSING for Bosch Security Systems Modem IIIa² Communication Format, or a Battery Missing/Dead (311) or Low System Battery (302) for Contact ID Format.
One self-resetting circuit breaker protects:
– Terminal 3: Auxiliary Power
– Terminal 24: Zonex Power.
NOTICE! A short circuit on one terminal disrupts power to the other terminal.
Another self-resetting circuit breaker protects:
– Terminal 6: Alarm Power Output
– Terminal 7: Alternate Alarm Power Output
– Terminal 8: Switched Auxiliary Power.
NOTICE! A short circuit on one of the terminals disrupts power to the other two terminals.
The third self-resetting circuit breaker protects Terminal 32: Power +.
What are the functions of the power output terminals?
The system produces up to 1.4 A of combined power at 12.0 VDC Nominal for all powered devices. The outputs listed below share the available power.
Terminal 3 – Auxiliary Power. Use this terminal to power devices requiring continuous power.
Terminal 6 (Relay A) – Alarm Power Output. Programmable relay normally open, power on alarm.
Terminal 7 (Relay B) – Alternate Alarm Power Output. Programmable relay normally open, power on alarm.
Terminal 8 (Relay C) – Switched Auxiliary Power. Programmable relay normally closed, switches power off when the Sensor Reset command is executed.
Terminal 24 – Zonex Power. Use this terminal to power Zonex modules such as the D8125, D8128D, and D8129 Modules.
Terminal 32 – Power +. Use this terminal to power serial device interface (SDI) devices such as keypads, the D9131A Parallel Printer Interface Module, and the D9210B Wiegand Control Interface Module.
What should I do if the programmable power outputs (Terminals 6, 7, and 8) do not provide the expected output?
If Terminals 6, 7, and 8 do not provide the expected output, check:
Programming for Relays A, B, and C in the relays section of the program.
Bell Parameters section of the program to confirm that the Alarm and Fire Bell responses are programmed for the expected duration and pattern.
Point Assignments section to confirm that each point is programmed for the expected local response.
How do I calculate the available alarm current for fire systems?
Fire systems are prohibited from using the battery for determining alarm power. Use the fire system power formula to calculate the current available for fire and combined fire and burglary systems.
To calculate the current available at Terminals 6 and 7 for fire and combined fire and burglary systems:
1. Add together the current draws for all devices connected to Terminals 3, 8, 24, and 32, and the accessory connector. This is the total current required for the normal standby condition (NSC).
2. The current available for NSC is 1.4 A. Subtract the NSC current required calculated in Step 1 from the NSC current available, 1.4 A. The difference is the alarm current available for Terminals 6 and 7.
In formula format:
1.4 A – NSC current required (Step 1) = Alarm current available
