19 - 20 - 21 : OUTPUT 3 -- (Output Relay 3)

1 Amp relay dry contact controlled by the Group 3 User PINs & Cards in Split-decoded mode or by

the RF remote key in Stand Alone mode. It is an auxiliary output ideally for controlling of security

system or automatic operator. Terminal 19 is Normally Closed contact (N.C.), terminal 21 is Normally

Open contact (N.O.) and terminal 20 is the common point of the two contacts.

(a) The operation of Output 3 is programmable from the keypad in

Split-decoded operation (with

Function Jumper on position 1). See programming Location 53 of the keypad for the details.

(b) The Output 3 is always fixed on Manual Momentary operation with Function Jumper on position

2 or 3 in Stand Alone mode. Manual Momentary means that the relay output works as long as

the button of the RF remote key is pressed. The relay output is released when the key button is

released.

22 : KEY ACT O/P -- (Keypad Active Output)

An NPN transistor open collector output with the maximum power rating of 24VDC/100mA sink. It

is equivalent to an N.O. (Normally Open) terminal referring to ground. It switches to (-) ground for

10 seconds on each key touch on the keypad or receiving of a command signal from the RF remote

key. It can be used to drive a small power device, such as a relay or a low power control point of

other equipment. See the Application Hints for more information.

23 : ALARM O/P -- (Alarm Output)

An NPN transistor open collector output with the maximum power rating of 24VDC/100mA sink. It is

equivalent to an N.O. (Normally Open) terminal referring to ground. It switches to (-) ground while

alarm occurs in order to trigger an external alarm to give notification at remote location. Use it to

drive a small power device, such as a relay or a low power control point of other equipment.

The Alarm Output for tamper is 3 minutes fixed. Other alarm outputs are programmable in Split-

decoded operation.

THE OUTPUT BEEP JUMPER

The controller gives beep sound when the relay output activates in stand alone mode or when

a command signal from the RF remote key is received. The beep jumper has been put on the

ON position at the factory. It can be stopped for silent environment by putting the jumper to OFF

position. The Jumper is located on the main circuit board. See Figure 2.
