Operating Guide

DIGITAL-KEY is a microprocessor controlled multi-purpose and easy to operate coded keypad that monitors the entrance of people to different sites and discreetly controls alarm and security systems.

After entering the secret authorized code, using the keyboard, it is possible to activate the integrated FIRST RELAY (by pressing digit No.1), or the SECOND RELAY (pressing digit No.2), or BOTH RELAYS simultaneously (pressing No.3).

The operating time of each relay may be programmed from 1 second to 64,999 seconds (18 hours). For special needs each relay may be operated in ON/OFF mode, so that entering the code once will lock the relay in ON position, and entering it again will release the relay- I.e. any entering of the code changes the relay's position.

On the front panel of DIGITAL-KEY there are Green and Red LED's, to be connected to an alarm system or accessories.

17 authorized codes may be set:
* 1 MASTER code.
* 15 SECONDARY codes.
* 1 TEMPORARY (one-use) secondary code.
All programming operations are accessible only to a person familiar with the Master-code. The programmer may limit any user to operate only certain relay(s).

In order to increase the security and to further protect against anyone trying to decipher the code through random pressing of keys: any faulty pressing shall turn the instrument off for 5 seconds. Furthermore, each digit from the code should be entered within 2 seconds, otherwise the device will be reset.
