NP-PTM
PROGRAMMABLE TIMER
WI1343A 12/05
DESCRIPTION
The NP-PTM programmable timer is appropriate for various
functions that require a timed operation, for example, Siren/
Bell Cut Off Modules, Dialer Delay, Access Control Applications, Guard Tour Supervisory Timers, etc. Some optional
functions include: One Shot, Delayed Release, Delayed Operate, Delayed Pulse and Pulser/Flasher. Includes a feature
that provides a momentary relay activation at the end of a desired timing cycle, eliminating the need for using two (2) timers to achieve this function. Another feature cancels
(interrupt) the timing cycle and reset the timer if desired.
FEATURES
• 12 or 24VDC operation is selectable.
• Quick and accurate time range adjustment from 1 sec. to
60 min.
• LED indicates relay is energized.
• Current Draw: Stand-by 3mA, Relay Energized 40mA.
• Triggers via positive DC (+) voltage, dry contact closure, or
removal of contact closure.
• Form "C" relay contacts are 8 amps at 120VAC/28VDC.
• Selectable relay activation at the start or end of the timing
cycle.
• One (1) second momentary relay activation at the end of
the timing cycle (eliminates the need to use two (2) timers
for this function).
• Built-in reset feature which cancels timing cycle.
• Repeat (pulser/flasher) mode.
• Snap Trac compatible.
• DIN Rail Mount version available.
Board dimensions: 76.3mm L x 63.7mm W x 25.0mm H
INSTALLATION INSTRUCTIONS
1. Mount NP-PTM (Multi-Purpose Timer) in desired location or
into an enclosure.
2. Set Dip Switch 3 for proper DC Input Voltage- 12VDC switch
ON, 24VDC switch OFF
3. Refer to Dip Switch 1 Selection and Dip Switch 2 Selec-
tion Tables for desired functions (e.g.: Timing, Trigger,
Pulse)
4. Refer to the Terminal Identification Table and Typical Ap-
plications (see fig. 8 on reverse) for desired wiring connections.
Note: It is good operating practice to measure and verify DC
input voltage before powering device to ensure proper operation.
Note: When triggering via a N.O. (normally open), momen-
tary or maintained trigger, connect the dry contact trigger to
Pos (+) and TRG terminals.
When triggering via a N.C. (normally closed), momentary or
maintained trigger, connect the trigger to Neg. (-) and TRG
terminals and install a 1K (1,000 ohm) resistor between the
Pos (+) and TRG terminals (fig. 8).

DIP SWITCH 2 SELECTION TABLE
DIP# Function/Description
The NP-PTM will go through an initial timing cycle when first
1
powered up unless DIP 1 is OFF.
If DIP 1 is OFF, timing can only be initiated via TRG terminal
DIP 2 is OFF puts timer in delayed output mode. Relay will pulse
2
for 1 second at
the end of a preset timing cycle. *Dip Switch 1 must be ON for
this function.
DIP 3 is OFF selects the pulser/flasher mode. Relay will flip ON
3
and OFF
continuously in equally set timed intervals when timer is powered
up.
