NAPCO NP-DTM7D24H-D User manual

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 Auto-
mation, Access Control, Lighting Control and more. The NP-
DTM7D24H-D is equipped with an independently controlled form
"C" relay contact providing many latching and/or momentary op-
erations 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.

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 pro-
grammed 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 combi-
nations of individual and block events may be programmed. Holi-
day exceptions are individually selected by date and will override
all regularly scheduled events.
The four (4) output relay modes consist of: 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.

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.
To program Daylight Saving Time (refer to D. Setting Block
Events (Weekly Repeat) and F. Daylight Saving Time).
To change or program clock/calendar simply repeat the steps
above.
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 us-
ing the UP and DWN push buttons until either:
ON - Relay ON (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 1-
second 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 pro-
grammed information of the event will be displayed. At this
point, depress the UP button to step up through the pro-
grammed 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)

cept. You may continue to program events by repeating the
previous steps or exit programming by depressing SET.
H. SETTING HOLIDAY DATES:
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 program-
ming, then change channel switch position, then enter pro-
gram mode again. It is now necessary to assign these holi-
day events specific calendar dates, which they are to occur.
Depress SET until appears in display.
Depress ENTER. will appear in display.
Enter the holiday date, day of week and year by depressing
UP and DWN to make the selection then depress ENTER to
accept.
Note: Holiday events will override all regularly programmed
events that occur on a particular holiday date.
I. DELETE/DISABLE EVENTS OR EDIT EVENTS:
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 program-
ming, then change channel switch position, then enter pro-
gram mode again. Previously programmed regularly sched-
uled and/or holiday events may be deleted/disabled without
having to erase all events.
Depress SET until appears in display.
Depress ENTER will appear in display.
Now scroll using UP and DWN push buttons to the event you
wish to delete, depress ENTER to move flashing cursor under
relay option, then depress UP and DWN push buttons until
DIS is displayed, depress ENTER to confirm.
J. DELETE ALL EVENTS:
This will delete all previously programmed events.

Depress ENTER. will appear in display.
Depressing UP push button will now clear all events previ-
ously programmed.
If you wish to escape from this selection, depress any of the
other push buttons: SET, ENTER and DWN.
K. TANDEM RELAY MODE:
To operate in the Tandem Relay Mode, close switch SW2
and cut R3. This mode setting will allow events programmed
for Channel A and Channel B to operate both relays simulta-
neously (1 DPDT relay output). This setting doubles the
amount of programmable events.
Note: When using the Tandem Relay mode, sequential ON/
Off or OFF/ON events must be programmed in the same
channel. (If there is a Channel Program conflict, such as
Channel A is set to ON and Channel B is set to OFF, the ON
command will override the OFF command and both relays will
remain ON).
