SECURITRON MODEL DPA-12 AND DPA-24 DOOR PROP ALARM TIMERS
INSTALLATION AND OPERATING INSTRUCTIONS
1. DESCRIPTION
The DPA series consists of a multifunction microprocessor controlled timer. Its primary function
is a sophisticated door prop alarm with numerous functions and options that permit tailoring its
alarm functions to the specific requirements of the end user. It is available as a circuit board
mounted on snap track via the part numbers: DPA-12 and DPA-24.
lockable steel enclosure with Sonalert and LED mounted, via the part numbers: BA-DPA-12 and
BA-DPA-24. Applications for the DPA series include doors with or without electric locks installed.
2. CIRCUIT BOARD OVERVIEW
Refer to Figure 1. The DPA board consists of five logic inputs, three SPDT relay outputs and four
Dip Switches. Two terminals for polarized power input are also provided. The DPA series is
available in separate units for either 12 VDC or 24 VDC operation. Note that DC power must be
regulated or filtered. The unit will not operate on pulsating DC (transformer + bridge
rectifier). The 12 volt version draws a maximum of 100 mA and the 24 volt version draws a
maximum of 50 mA. These maximums are present when all three output relays are energized.

3. BASIC OPERATION
The operation of the DPA occurs in four different stages.
condition. In this stage the door is closed/secure and inputs IN and LS are receiving +V. The
output relays are in their normal conditions: relays #1 and #2, deenergized and relay #3,
energized.
The next stage is the authorized condition.
This range can be digitally set for 30, 60, 120 or 240 seconds. During the authorized condition,
the output relays remain in their normal states. The time period selected is the amount of time
that the user feels is acceptable for normal door use . Note that it doesn't really matter if the
door is electrically locked and employs an access control device or if the door is simply equipped
with a panic bar. The central function of the DPA is to prevent doors being propped open too
long.

- Page 2 The next stage is pre-alarm. If the door has not been reclosed/resecured before the end of the authorized condition (time range one), relays #1 and #2 energize and time range two begins. Relay #1 is connected to the Sonalert on the BA-DPA enclosure and the Sonalert will sound at the door.
- Page 3 case the DPA returns to normal condition. In the pre-alarm condition, relays #1 and #2 begin to signal. The length of this condition is defined by time range two, unless the door recloses before the end of time range two. In that case, again, the DPA automatically returns to the normal condition.
- Page 4 5.1 FORBIDDEN CONDITION DETECTION If you have both a door status switch and lock status switch available, DOOR STATUS you can employ the DPA in a higher security mode that includes a SWITCH CONNECTS TO "IN"; LOCK unique type of tamper detection. To understand this feature, you must STATUS TO "LS".
- Page 5 closing or resecuring the door. The act of doing this will send a +V reset input to RS and reset will be accomplished automatically. It's worth noting that wiring for auto reset has an effect on forbidden condition detection. When you have made connections to both lock status and door status signals, a forbidden condition alarm will be given instantly if, at any time, the door reads open while the lock reads secure.
- Page 6 The duress input can be used. A signal must be made available which closes when the door opens. During the day the time clock relay TIME CLOCK RELAY blocks this closure with open contacts. At night, the time clock relay CLOSES AT NIGHT contacts close and any time the door is opened, the DPA goes into FOR INSTANT ALARM...
