Altronix AT4B 4 Inch Annual Event Timer

Overview

Altronix AT4/AT4B are extremely versatile 24 Hour 365 Day Event Timers designed to support a wide range of applications. Such applications include: Home and Building Automation, Security, Access Control, Lighting Control, etc. AT4/AT4B are equipped with four independently controlled form “C” relay contacts that provide many latch-ing and/or momentary operations during a program schedule of your choice. The EE prom memory allows for programming of unit prior to/or during field installation. Events may be set for single or multiple operations on a daily and/or weekly schedule. The block programming feature enables repeating an event on any combination of consecutive days. AT4/AT4B will compensate for daylight savings time if desired. It automatically adjusts for leap year. Individually selected holiday exceptions can be programmed to override regularly scheduled events.

Programming Instructions
Connect 12 to 24 Volts AC or DC to terminals marked – DC +
When using DC carefully observe polarity.
Connect 12VDC battery (optional) to terminals marked BAT – and BAT +
Insert lithium battery (not supplied or required. Altronix part # LB2032) in battery holder.

Note
Lithium Battery LB2032 must only be installed after initial power up of AT4/AT4B. Connect devices to be controlled to dry outputs marked RLY1 NC, NO, C – RLY4 NC, NO, C. It is important when connecting DC powered electromechanical devices such as Mag Locks, Electric Strikes, Bells, Relays, etc. to install a catch diode across the pos + and neg – terminals of the device. Connect diode as close to the device as possible with the banded side facing the pos (+) terminal. This will reduce the possibility of interference. Program clock and desired event schedule.
