7286 SERIES DOOR PROP ALARM USER MANUAL
Overview
The 7286 Door Prop Timer sounds an alarm when a door being monitored remains open beyond a user
set time limit, or if the door is opened without a valid Request for Access (REX).
INPUTS VOLTAGE
12 or 24 Vdc
REX Request for access (REX) input connect to normally open dry contact device such as card
reader, pushbutton, or motion detector.
REX RESET A closed contact at the RECYCLE input enables REX during alarm condition. Normally, REX is
disabled by alarm.
DOOR POSITION Connect to door position switch or bond sense switch to monitor door status. Supervised input
is available as an option.
ALARM SHUNT Closed contact (keyed switch or similar) at input disables alarm.
OUTPUTS LOCK POWER
Magnetic lock or electric strike can be powered directly. Select fail-safe or fail-secure operation
by jumper.
AUDIO POWER Power connection for local or remote sounder. Select high or low volume by jumper.
DPS MIRROR OUT Relay output follows Door Position Switch status – contacts close when door is closed.
ALARM OUT SPDT Relay contacts. Relay is energized during alarm.
SHUNT STATUS OUT SPDT Relay output follows SHUNT input.
SETTINGS WARNING TIME Is adjustable from immediate alarm to 5 minute warning.
PROP TIME
Is adjustable from no delay to 90 minutes.
AUTO RESET Auto alarm reset time.

INSTALLATION
INPUT CONNECTIONS
POWER: Power supply voltage must match lock requirements, either 12V or 24V dc and the current
rating should exceed the expected load including the lock, lights, sounder and control circuitry. A
minimum current rating of 1 Amp @ 12 Volts is recommended. Some installations will require a larger
supply. Make sure the power connection polarity is correct.
RESET: An Alarm is continuous until reset. Connect a normally open, momentary contact switch to
the Reset input for manual reset or a normally closed contact switch (or wire jumper) for automatic
reset. See SETUP (below) to adjust the auto reset timing. To prevent unauthorized manual reset, the use
of a keyed switch, a keypad with numeric code or card reader is recommended.
DPS/MBS: Connect either a Door Position Switch (DPS) or a Magnetic Bond Sensor (MBS) to the
DPS input. Contacts must be closed when the door is secure.
REX RECYCLE OPTION: Normally the REX input is ignored while the system is in alarm. With
closed contacts at the REX RECYCLE input, either a normally closed switch or a wire jumper, a REX
input will reset the alarm if the door is secure.
SHUNT: Connect a maintained contact switch (typically a keyed switch) to the Shunt input to disarm
the alarm function. When the switch contacts are closed, the alarm is disabled even if it is active. If the
SHUNT switch contacts are opened while a door is open the system will go into alarm immediately.
REX: Connect the dry output, normally open contacts of a pushbutton, keyed switch, digital keypad,
card reader, or other access control device to the REX input.

Rev G 3-4-15 3
OUTPUT CONNECTIONS
DPS MIRROR: Connect the Mirror relay output to any external device (or console) for monitoring the
door status. The output follows or “mirrors” the Door Position Switch.
ARM RELAY2: Connect the Arm output to any external device used to monitor or indicate the status
of the alarm bypass.
ALARM RELAY1: Connect the Alarm relay output to any device used to monitor or indicate an alarm
(horns, lights etc.).
LOCK: Connect a magnetic lock or electric strike to the powered Lock output. Use properly sized
conductors for the load and wire run. 18 Gauge or larger is recommended. Select either fail-safe or fail-
secure operation by installing a jumper at JP-10 of Header 1, see SETUP below for more details.
LED: A dedicated 3 pin header is provided for connecting a bi-color LED to indicate system status.
The middle pin (see diagram above) is common. The top pin (shown connected to red LED) is powered
when the system is in alarm and cycles on and off during warning mode. The bottom pin (shown
connected to green) is powered when the system is idle and operating normally. Both pins are powered
(amber) when the door is unlocked and power cycles on and off when the door is open.
HEADER 1
JP5 (AUDIO OUT): Connect a piezo sounder rated for 9 to 12 volts DC to JP5 – observe correct
electrical polarity.
HEADER 2
The 7600 interface connector is used to interface the 7200 to the Dortronics 7600 Annunciator unit. All
connections are isolated dry contact. Polarity does not matter:
ARM: Connects to the ARM input of the 7600.
ALARM: Connects directly to the ALARM input of the 7600.
DOOR: Connects directly to the DOOR input of the 7600.
A separate 7286-PT unit must be used for each individual zone of the 7600 on which door prop
protection is needed.

Rev G 3-4-15 4
SETUP
SETTING THE PROP TIME: The prop time is adjustable from 0 seconds to 90 minutes. A 16
position rotary switch is used to make the adjustment. The switch is labeled 0-9 and A-F. Refer to
the chart below for switch settings to achieve various timer settings.
JP4 (AUDIO VOLUME): The volume of the audio sounder can be adjusted for low or high
volume. Install a jumper on JP4 for high volume. Remove the jumper for low volume.
JP7: (FORCED DOOR BY-PASS): Install a jumper at JP-7 for doors without a REX (normally
unlocked or monitored by others). Prop timer starts when the door opens. Forced door alarm is
disabled. For installations without a REX, the jumper must be used to prevent continuous alarm.
JP10 (FAIL SAFE / SECURE): Set Lock Output logic to either cut power for unlock (typically
used with a magnetic locks or a fail-safe strike) or provide power for unlock (typically used with
fail-secure strike). With NO jumper - power is OFF for unlock. With jumper installed -
power is ON for unlock.

A - SETTING THE AUTO-RESET TIME: Use a small screw driver to turn the adjusting
screw of the RESET trim pot (A) – clockwise to increase the delay up to 5 minutes and
counterclockwise for less or none. This is a multi-turn adjustment. An exact setting or a very
short delay may require more than one adjustment.
B - SETTING THE WARNING TIME: The multi-turn trim pot to adjust the duration of the
propped door warning (B) is adjustable from no delay to 5 minutes. Turn clockwise to increase
and counterclockwise for less or none. An exact setting or a very short delay may require more
than one adjustment.
Note: trim pots do not have stops at the limit of travel. They use a clutch to prevent damage
from excessive turning. Once the clutch disengages at the end of travel (in either direction)
additional turns have no effect on the time setting.
IMPORTANT!
When the Reset input is closed and the Auto-Reset time is less than the
Warning time the system will not go into alarm.
If the system does not alarm as expected, rotate the Reset adjusting
screw two or three turn clockwise to increase the reset delay.
Once the alarm is working, adjust the screw for the desired delay before
auto-reset.

OPERATION
IDLE:
In normal operation, the door being monitored is closed. The Lock Output is powered (for
magnetic lock) or not powered (for electric strike). The alarm relay is de-energized. The sounder
is quiet. No timers are running. The LED status lights are green. The alarm is armed.
REQUEST FOR ACCESS:
Contact closure at the REX input changes the state of the LOCK output (depending on the fail-
safe or fail-secure setting, the default being fail-safe) releasing the door lock. The door is now
accessible. The indicator light changes from green to amber. The door will remain accessible for
as long as the REX input contacts are closed. The REX device must be adjusted to provide
sufficient time delay for the user to initiate a request and then move to open the door. The ideal
delay time will vary by installation. If the REX contacts open before the door is opened, the
system returns to IDLE and the door is no longer accessible.
OPEN DOOR WITH VALID REX:
During the unlock period, the door may be opened. When the DPS input sees open contacts, the
indicator light changes to blinking amber. The internal door prop timer begins counting down the
pre-set prop time. If the door is still open when the prop timer expires, the system enters the
WARNING period – see below.
DOOR CLOSE WITH NO ALARM:
In normal operation the door will close before the prop timer has timed out and the system returns
to IDLE.
PROP WARNING:
If the door remains open after the prop timer has timed out, the WARNING timer begins. During
the warning phase, the sounder beeps and the indicator light flashes red. If the door is closed
during the warning period, the system returns to IDLE.
DOOR PROP ALARM:
If the door remains open when the warning timer expires, the system enters ALARM state, the
sounder tone is continuous and the indicator light is steady red. The system will remain in
ALARM state until it is reset. Note, the alarm relay is not energized during the warning period.
DOOR OPEN ALARM:
With the WARN adjustment set to zero, and the prop time set to zero, the system goes into
ALARM as soon as the door opens.

Rev G 3-4-15 7
MANUAL RESET:
Momentary closed contacts at the RESET input will clear an alarm and return the system to IDLE
if the door is closed and secure.
AUTO RESET:
With maintained closed contacts at the RESET input (or wire jumper), the system will auto-reset.
The auto reset may be timed or immediate depending on the setting of the RESET trim pot.
1. With closed contacts (or jumper) at the Reset input, the system will clear an alarm when
the auto-reset timer expires if the door is left open.
2. With the Reset Input shorted, the system will clear an alarm if the door closes before the
auto-timer expires. See Setting the Auto Reset Timer.
FORCED DOOR ALARM:
If a door is opened without a valid REX (forced) the system goes into ALARM mode. The
sounder tone is constant and the indicator is steady red. On manual reset the system returns to
IDLE if the door is closed.
REX RECYCLE (RESET ON REX):
A request for access (REX) signal is ignored during an Alarm condition unless the REX
RECYCLE input is closed. When the RCY input is closed, (with a switch or wire jumper) a REX
contact closure will reset an alarm and return the system to IDLE. The door must be secure.
SHUNT (ALARM BYPASS):
When the SHUNT input is closed, the alarm sounder is silenced and the alarm relay is bypassed.
A propped door and or a forced door will not result in an alarm. The LED will change to amber to
indicate that the system is in SHUNT and that the alarm is bypassed. An open door while in
SHUNT mode will cause the LED to flash amber.
