NAPCO NP-PTM User manual

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 Applica-
tions, Guard Tour Supervisory Timers, etc. Some optional
functions include: One Shot, Delayed Release, Delayed Op-
erate, Delayed Pulse and Pulser/Flasher. Includes a feature
that provides a momentary relay activation at the end of a de-
sired timing cycle, eliminating the need for using two (2) tim-
ers 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 connec-
tions.
Note: It is good operating practice to measure and verify DC
input voltage before powering device to ensure proper op-
eration.
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 1 SELECTION TABLE
DIP# Function/Description
1 The NP-PTM will go through an initial timing cycle when first
powered up unless DIP 1 is OFF.
If DIP 1 is OFF, timing can only be initiated via TRG terminal
2 DIP 2 is OFF puts timer in delayed output mode. Relay will pulse
for 1 second at
the end of a preset timing cycle. *Dip Switch 1 must be ON for
this function.
3 DIP 3 is OFF selects the pulser/flasher mode. Relay will flip ON
and OFF
continuously in equally set timed intervals when timer is powered
up.
