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.

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

TERMINAL IDENTIFICATION
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.
