Overview:
Altronix models PT724A/DPT724A/PT724AE 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. PT724A/DPT724A/PT724AE are equipped with an
independently controlled form “C” relay contact that provides many latching
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. PT724A/DPT724A/PT724AE will
compensate for daylight savings time if desired. Individually selected holiday
exceptions can be programmed to override regularly scheduled events.

Installation Instructions
-
Mount PT724A/PT724AE/DPT724A in desired location.
Carefully Review:
Basic Operation (pg. 3)
Terminal Identification Table (pg. 3)
Push Button Layout and Description (pg. 4)
Programming Instructions (pg. 4-6) -
Connect 12 to 24 volts AC or DC to terminals marked [+ DC – / ~ AC ~].
When using DC carefully observe polarity. -
Connect 12VDC battery (optional) to terminals marked [+ BAT – / 12VDC].
-
Insert lithium battery (optional/not included. Order part LB2032) in battery holder (Fig. 1, pg. 3) with the + positive side facing up.
-
Connect devices to be controlled to dry outputs marked [NO, C, NC].
Note: 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 (see programming instructions pg. 4-6).
Basic Operation:
PT724A/PT724AE/DPT724A controls an independently operated dry form “C” relay
output. Relay can be pro-grammed to: turn on (latch), turn off (release latch)
or pulse (momentary toggle) at a specified time and day (this is referred to
as an event). Events are programmed via the push buttons and LCD display.
Events may be programmed to occur on any day of the week at any time. In
addition, events may be repeated at a specific time on two (2) or more
consecutive days (i.e. M-F, Sun-Th, etc). Multiple combinations of individual
and block events may be programmed. Holiday exceptions are individually
selected by date and will override all regularly scheduled events.
Output Relay Modes:
Mode | Status |
---|---|
Relay OFF | De-energizes the relay until a relay ON event is detected. |
Relay ON | Energizes the relay until a relay OFF event is detected. |
Disable | Used to cancel an existing programmed event. |
Pulse | Momentarily energizes the relay for a selectable time period of 1 sec. |
to 15 secs.
Time is displayed in 24 hr. military format.
Terminal Identification Table
Terminal Legend | Function/Description |
---|
NO, C, NC
| Dry Contact output used to switch controlled devices. When these relays are
energized (ON) the NC and C terminals are open and the NO and C terminals are
closed. When this relay is de-energized (Off) the NC and C terminals are
closed and the NO and C terminals are open.
+ DC – ~ AC ~| AC or DC Input 12 to 24 volt. When using DC carefully observe
polarity
+ BAT – 12VDC| 12VDC stand-by battery input (battery leads provided).
FM
| When this terminal is connected to DC neg. (–) the “First Man in” feature is enabled. The relay will remain in its present position until this connection is terminated. At that time the relay will resume normal operation and latest scheduled events will occur.
