16 Installer Manual SATEL

The control panel can operate both with LCD and LED keypads in any configuration.

Notes:

• We recommend keypad CA-10 LED-S v1.2 or newer to be used, because older keypads

LED S may work incorrect with keypad LCD v3.08 and next version (it regards to the

CA-10 KLED-M keypads, which were produced earlier, as well).

• Only zone expanders with version 2 are allowed (label dated February 1998 or later).

• The LCD display is fragile. It can be broken if the keypad is dropped to the floor!

● After power-up of the KLED-S keypad, and when the control panel quits the service mode,

the keypad will remain disabled and will not react to pressing any keys for 5 seconds.

During that time the system settings are being read, and the keypad backlight is blinking

with a high frequency. Simultaneously, the keypad restores the automatic mode of keypad

illumination. The mode can be changed with the user function by holding down the key [9].

The keypads should be connected to the control panel connectors COM, +KPD, DATA,

CLK1, CLK2, CLK3, CLK4. The connectors COM, +KPD and DATA are common for all

partitions, while the connectors CLK1, CLK2, CLK3 and CLK4 determine the partition the

keypad belongs to. Where the system will be operated with less than 4 keypads, they should

be connected starting from the CLK1.

The keypads should not be connected in parallel to one CLK signal (one partition – two

keypads). It applies to all LCD keypads, as well as the CA-10 KLED-S keypads. The only

exception are the CA-10 KLED keypads, which may be connected in parallel.

Each keypad should be connected with a separate cable. The distance between the keypad

and the panel can be up to 200 m. Unscreened cables are recommended to be used for

connecting the keypads.

It is recommended to use an untwisted unshielded cable 8x0,5 mm

(do not use twisted pair

cables). With recommended cable, the following distances between keypad and control panel

may be used to ensure appropriate power supply:

The keypads may be power supplied from the +KPD panel connector only. This output

can also be used for power supply of the keypad connected detectors.

As the LCD keypad current consumption is larger than that of the LED keypad (particularly

with active illumination of the keypad and display), it is important that resistance of the power

supply and ground lead-ins be taken into account when planning the cabling installation.

Caution: The supply voltage measured across the terminal block of LCD keypad with active

backlighting should not be less than 11 V.

The keypad tamper contact has no connection with the system anti-tampering circuit. Its state

is defined by the control panel, based on the data received from the keypad. When the

control panel is in the service mode, the tamper contact is not controlled.
