Frequently Asked Questions - 1068/021 GROTHE

How to open the 1068/021 keypad?

Apply light pressure with a flathead screwdriver on the indicated point (locking tab) to release and lift the cover. The locking screw is at the bottom (hole F).

What is the power supply of the keypad?

The keypad is powered via the control panel communication bus. The nominal voltage is 13.8 Vdc, with a range of 9 to 15 Vdc. Maximum current consumption is 93 mA.

How to connect the keypad to the bus?

Use a shielded 4-conductor cable (2 for power, 2 for data). The total bus length must not exceed 400 meters. Connection can be daisy chain or star.

How to perform a factory reset?

Disconnect power, open the tamper, then reconnect power. Within 10 seconds, press the F1 key. Confirm the reset by pressing F1 again or cancel with F3.

How to enroll the keypad on the control panel?

On first power-up, press the key associated with the F1 symbol on screen. Follow the instructions in the control panel manual to finalize enrollment.

What do the LEDs on the keypad mean?

The 3 LEDs indicate: power (mains present), warning (fault or alarm), and zone status (armed/disarmed).

How to connect a detector to the IN1 input?

Connect the detector to input IN1 (ground). It can be programmed as NC, NO, single or double balanced. For double balanced (EN50131 compliant), use the supplied 2.7 kΩ resistors.

Is this keypad compatible with all GROTHE 1068 series control panels?

Yes, the 1068/021 keypad is designed for use with 1068 series control panels. Refer to the control panel manual for programming details.

What is the applicable safety standard?

The keypad complies with EN50131 for alarm systems. Double balanced connection is mandatory for compliance. The tamper jumper allows excluding the opening button but invalidates certification.

How to clean the keypad?

Use a soft, dry cloth. Avoid chemical or abrasive products. Do not spray liquid directly on the device.

GENERAL DESCRIPTION

The 1068/021 indoor display keypad, used to control and program the 1068 series system is equipped with :

• LCD backlit display with contrast and luminosity regulation;
  • 3 LED to signal the system status (Power supply, Recommendations, Zone status);
  • 18 door-protected alphanumerical keys;
• buzzer with adjustable volume;
• 1 programmable input.

A tamper jumper is supplied with the product to bypass the keypad opening/removal button. Use of this feature will cancel EN50131 certification.

The keypad is powered by the bus that connects it to the control panel.

WARNING! In this document there are only present some essential indications about product. For further and more detailed information, refer to manuals concerning 1068 series control panels.

POSITIONING

Keypad must be positioned:

• in an environment that is sheltered and protected from water and humidity;
  • on a dry and level wall;
• in the vicinity of the accesses to area to be protected;
• in an inner location which is not subjected to excessive sudden rises/falls in temperature, and is protected by anti-burglar system; at 160 cm height for normal installations. For disabled or special needs users of the D1 type (elderly) and D2 type (lower limb motor

difficulties), the centre of the device must be arranged at a height comprised between 75 cm and 140 cm with respect to the floor. For more details, see technical standard CEI 64-21:2016-12 – Residential environments. Systems suited for use by people with disabilities or special needs.

KEYPAD OPENING

Use a slotted screwdriver to open the keypad by gently pressing the point indicated in the image in order to disengage the closure spur and lift the cover (Fig. 1).

INSTALLATION

• For running the cables, open the provided hole on the bottom of the keypad (D - Fig. 2). Otherwise, the scored holes for the cable ducts can be used (E - Fig. 2).
• Secure the keypad bottom to the wall by means of 6 mm plugs (A/B - Fig. 2 - not provided). During fixing always use also the hole (C - Fig. 2) for the protection against removal.
• If bottom is fastened over round or rectangular a 3-place built-in box (e.g. BTICINO 503), use holes (A or B) and suitable screws.
  WARNING! before fixing, verify the bottom direction: cover closing hook shall be positioned at the bottom.
• For easier wiring, it is advisable to strip the cable as far as the access hole.

- Close the keypad by screwing the screw provided in the hole. (F - Fig. 1).

BUS CONNECTION

Keypad can be connected on bus either in a cascade or star. Keypad position along bus is not important. The overall length of all bus sections must not exceed 400 metres.

For wiring, use 4 lead screened cable for anti-intrusion (2 leads for power supply and 2 leads for data connection). Lead section must be chosen taking into account voltage drop caused by connection length. In counting out overall system absorption, also consider max consumption in keypad (95 mA).

POWER SUPPLY AND DATA BUS

KEYPAD CAPTURE

To acquire the keypad the first time it is switched on, press the key associated with the F1 symbol that appears on the display.

Proceed as follows to restore default settings (Reset) on the keypad, if necessary:

• Disconnect power from the keypad
• Open the keypad tamper protection
• Restore power supply to the keypad
• Press the key associated with the F1 symbol within 10 seconds (Fig.3). Another screen will appear (Fig.4).
• Press the key associated with the F1 symbol to confirm parameter reset. Press the key associated with F3 “Cancel” symbol to return to the previous screen

ALARM INPUT

Possibly connect a sensor to the auxiliary input IN1. The input is referred to ground (-) and can be programmed as NC, NO, Single balancing and Double balancing. The input can also manage fast signals coming from seismic sensors or rolling shutters; in this case, the connecting mode is fixed on NC. In order to connect with balancing use the provided 2.7kohm resistors with 1% tolerance.

WARNING! "Double balance" is the only EN50131 compliant connection mode. Refer to the manuals of 1068 series control units for further, more detailed information.
