HPT724

Product Installation Document

1 Overview

The Honeywell HPT724 is a programmable LCD timer that is designed to support a wide range of applications. Such
applications can include: home and building automation, security, access control, lighting control, etc. The HPT724 is
equipped with an independently controlled form “C” relay contact that provides many latching and/or momentary
operations during a program schedule of your choice. The EE prom memory allows for programming 24 hour 365 day
events prior to/during field installation. Events may be set for single or multiple operations on a daily and/or weekly
schedule. The block programming feature enables repeating and event on any combination of consecutive days. The
HPT724 will compensate for daylight saving time if desired. Individually selected holiday exceptions can be
programmed to over-ride regularly scheduled events.

2 Specifications

• 12/24 volts, 500mA AC or DC operation.

• Standby Current: 10 mA (relay off), 50 mA (relay on).

• Battery Charging Current: 100 mA.

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

• EE Prom memory protects against loss of programming due to power failure.

• Accurate crystal-controlled clock (displays time in military format).

• 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 settings.

• Automatic compensation for leap year.

• Built-in charger for 12 VDC sealed lead acid or gel type batteries (standby battery maintains operation during power
failure until discharged).

• Lithium battery backup maintains clock (optional; battery is 3V, model CR2032).

• Board Dimension: 5.25"W x 3"L x 1"D (approximate).

3 Installation Instructions

1. Mount HPT724 in desired location, using suitable standoffs/fasteners, tape or HST34 snap track.

2. Connect 12 or 24 volts at 500 mA of AC or DC to terminals marked [+DC-- ~AC~]. (When using DC, carefully
observe polarity.)

3. Connect 12 VDC battery (optional) to terminals marked [+BAT-- 12VDC].

4. Insert lithium battery (optional/not included) in battery holder with the positive (+) side facing up (Fig-1).

5. Connect devices to be controlled to the dry outputs marked [NO, C, NC].

6. Program clock and desired event schedule (see Sec-5).

NOTE: When connecting DC powered electromechanical devices such as Mag Locks, Electric Strikes, Bells, Relays, etc. install a catch diode

..

across the positive (+) and negative (-) terminals of the device. Connect diode as close to the device as possible with the banded side facing the
positive (+) terminal. This will reduce the possibility of interference.

4 Basic Operation

The HPT724 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 -- 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 to 15 seconds.

(Time is displayed in 24 hour military format.)
