RELAY BOARD – DOOR ENTRY / PUBLIC ADRESS (WK026CRG)
This optional card connected via a flat ribbon cable to telephone card WK140MLB, enables the
activation of a relay from a remote telephone or system. This relay can activate for example:
•
electric door entry mechanism
•
lighting
•
public address amplifier with loudspeaker
In its factory setting, the code to activate the relay is1. This code must ALWAYS be keyed
between two * characters. Keying * 1 * from a remote telephone will therefore activate the relay.
Wherever a double relay card (WK026CR2G) is used, the second relay is activated by code *2*,
by adding 1 to the first relay code value.
Keying this code on the keypad of a telephone equipped with a relay board will not activate its
own relay.
In the factory setting, the activation time of the relay is 2 sec. The DTMF code * is used to de-
activate the relay. The activation code (up to 4 digits) and the time (value between 00 and 99
seconds) are modifiable (see programming page 22).
