NP-DTM7D24H-D

DUAL ANNUAL EVENT TIMER

WI1345A 12/05

DESCRIPTION

The NP-DTM7D24H-D is a two channel 24 Hour / 365 Day
Timer Controller used to support a varied range of applications,
including but not limited to: Security, Home and Building Auto­mation, Access Control, Lighting Control and more. The NP­DTM7D24H-D is equipped with an independently controlled form
"C" relay contact providing many latching and/or momentary op­erations during a program schedule of your choice. The EPROM
memory allows you to program the unit prior to/or during field
installation. Events can be set for single or multiple operations on
a daily and/or weekly schedule. The block-programming feature
allows repeating an event on any combination of consecutive
days. NP-DTM7D24H-D compensates for daylight saving time if
desired. Also, individually selected holiday exceptions can be
programmed to override regularly scheduled events.

FEATURES

• Standby current: 10mA (relay OFF) 50mA (relay ON).

• 12 to 24 volts AC or DC operation

• Battery charging current: 100mA.

• Two form "C" relay contacts are rated 10Amps

@120VAC/28VDC.

• Tandem relay mode (converts 2 SPDT contacts to 1 DPDT

contact).

• EE-Prom program memory protected against power loss.

• Accurate crystal controlled clock.

• Momentary and/or Latching Events.

• 50 individually programmed daily/weekly events.

• Block programming capacity can accommodate a total of 350

events per week.

• 10 programmable Holiday dates.

• "First man in" option.

• Alphanumeric LCD display simplifies programming.

• Standard or Daylight Saving Time settings.

• Automatic compensation for leap year.

• Built-in charger for 12VDC sealed lead acid or gel type batter-

ies (Max charge current 100mA).

• Lithium battery backup maintains clock (optional).

• User-friendly programming.

Board dimensions: 30mm(H) x 135mm(W) x 92mm(L)

INSTALLATION INSTRUCTIONS

1. Mount NP-DTM7D24H-D in desired location / enclosure.

Carefully Review:

• "Basic Operation" (below)

• "Terminal Identification Table" (below)

• "Push Button Layout" and "Description" (page 2)

• "Programming Instructions" (pages 2-3)

2. Connect 12 to 24 Volts AC or DC to terminals marked
[+ DC -, ~ AC ~]. (When using DC carefully observe polarity).

3. Connect 12VDC battery (optional) to terminals marked
[+ BAT -, 12VDC].

4. Insert lithium battery (optional/not supplied--order part
CR2032) in battery holder, with the + positive side facing up.

5. Connect devices to be controlled to dry outputs marked [NO,
C, NC].

Note: It is important when connecting DC powered electrome-

chanical devices such as Magnetic 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.

6. Program clock and desired event schedule (see Programming
Instructions, pages 2-3).

BASIC OPERATION:

NP-DTM7D24H-D controls an independently operated dry form
“C” relay output. Relay can be programmed 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.

The four (4) output relay modes consist of: Relay OFF - De­energizes 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.

PROGRAMMING INSTRUCTIONS:

Note: The flashing cursor denotes location of data entry se-

lection to be made. If an entry was made in error or requires
changing, depress SET to backspace, make the correct se­lection and depress ENTER to accept data and advance the
cursor.

A. SETTING CLOCK/CALENDAR:

Upon initial power up will appear in display.

Depress SET. will appear in display.

Depress ENTER. will appear in display.

Enter the current date, day of week and time (military) by de-

pressing UP and DWN to make the selection then depress
ENTER to accept.

B. SETTING EVENTS:

Depress SET until "ENTER TO SET EVENT" appears in display.

Depress ENTER. will appear in display.

Note: A01 indicates Channel A event 01.
When cursor appears you are able to scroll through events.
Depress ENTER until the flashing cursor appears under OFF

in display. Now select type of event required by scrolling us­ing the UP and DWN push buttons until either:

ON - Relay ON (latching mode).
OFF - Relay OFF (latching mode).
PL - Relay Pulse (momentary).

...appears in display and depressing ENTER will make the

selection.

When selecting the pulse mode, PL01 will appear in the dis-

play. It is now necessary to assign the length of time (duration
of relay activation). The pulse can range in length from 1­second minimum to 15-seconds maximum and is selected by
using UP or DWN push buttons, and then depressing ENTER
to accept.

Note: If pulse duration is not selected, relay output defaults to

1-second. Next, select the day of the week or BK* for weekly
repeat and time (military) by scrolling using UP and DWN
push buttons and depressing ENTER to accept. You may
continue to program events by repeating the previous steps or
exit programming by depressing SET.

Note: When programming additional events, it is necessary

to select the next consecutive event number following the last
event program to continue.

Note: When it is required to have the same event repeated

on two (2) programmed as a block by selecting BK in the day
field.

Note: To program the consecutive days of the week, refer to

D. Setting Block Event (Weekly Repeat) and F. Daylight
Saving Time.

C. ADDING EVENTS

Depress SET until "ENTER TO SET EVENT" appears in display.

Depress ENTER. will appear in display.

Depress ENTER. If the event is not programmed, the cursor

will move to the OFF (relay function) position. If the event is
programmed, the cursor will move to the position and the pro­grammed information of the event will be displayed. At this
point, depress the UP button to step up through the pro­grammed events. When an unprogrammed event is reached,
the cursor will move to the OFF (relay function position). (At
this point, see Setting Events or Setting Holiday Events).

D. SETTING BLOCK (WEEKLY REPEAT)
Select channel A or B by moving slide switch SW1 to ap-

propriate position.

Note: Channel cannot be changed in the middle of program-

ming events. To change channels, you must exit program­ming, then change channel switch position, then enter pro­gram mode again.

Depress SET until appears in display.
