NP-DTM7D24H

SINGLE ANNUAL EVENT TIMER

WI1344A 12/05

DESCRIPTION

The NP-DTM7D24H is a 24 Hour / 365 Day Event Timer that
supports a varied range of applications, including but not lim­ited to: Security, Home and Building Automation, Access
Control, Lighting Control, etc. The NP-DTM7D24H is
equipped with an independently controlled form “C” relay con­tact that provides many latching and/or momentary operations
during a program schedule. 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.
The NP-DTM7D24H compensates for daylight saving time if
desired. Also, individually selected holiday exceptions may
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.

• Form “C” relay contacts are rated 10Amps @120VAC/28VDC.

• EPROM memory protects against loss of programming due to

power failure.

• 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 batteries

(Max charge current 100mA).

• Lithium battery backup maintains clock (optional).

• User-friendly programming.

Board dimensions: 30mm(H) x 135mm(W) x 77mm(L)

INSTALLATION INSTRUCTIONS

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

Carefully Review:

• "Basic Operation" section (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 electro-

mechanical 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 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 second to 15 seconds. Time is displayed in 24 hr.
military format.

this relay is de-energized (OFF) the NC and C terminals are closed and the NO and C
terminals are open.

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.

When selecting the pulse mode PL01 will appear in the

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