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. Fig. 1DS1068-008A 3 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).

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.
