Dortronics 7286 Series Door Prop Alarm on 1 Gang Plate with LED and Piezo Audio AlarmThe 7286-PT series of door prop alarms provide an audible warning sounder, at the door, if it is not closed within a specified time. Upon a forced door condition or if the door has not been closed during the warning period, an alarm relay is activated and can be utilized to signal other monitoring systems. A piezo alert is also sounded locally.Features:Universal Operation:Opening the door, or an authorized rex will activate the PT timer. If the opening is forced an immediate alarm is sounded and signaled to monitoring systems. The allowed door open timer starts upon an authorized door opening. If the door has not closed at the end of this period, a local warning period begins. If the door remains unsecured past this time period, then an alarm condition is triggered. When supplied with the optional push button, a second set of momentary switch contacts are available to provide a R-E-X signal to an access control system.Adjustable Exit Time Period:The allowed “door open” time may be set from 0 seconds to 90 minutes. This timer begins when the door has opened and the “door unlock” signal from the access system ceases. A warning will sound if the door has not been closed at the end of the time period.Adjustable Warning Time Period:The “warning” period may be set from 0 seconds to 5 minutes. During this sequence the sounder emits a beeping tone to remind the user to close the door. If the door is not closed before the end of this warning period, then the “door prop” alarm sequence is activated. At this point the alarm relay is activated and the local sounder emits a steady alarm alert. This alarm is continuous until reset one of 3 ways, 1: upon door closure, 2: by auto timed reset, 3: manual reset by key switch, digital keypad or other N.O. device The use of a door position switch is required.Compact Mounting Styles:The Dortronics PT door prop modules are available in any of the #7286 series single or double gang wall plate designs. The single plate will accommodate the PT module with sounder and LED. When used with mushroom pushbuttons or key switches a double gang plate is required.LED Indicator:A tri-state LED is provided for a visual indication of the door prop alarm condition. The LED is green when the door is secured, amber during door unlock/shunt, flashing amber when door is open (authorized), flashing red during the warning period, and steady red while in alarm.Economical single door monitoringAdjustable exit time and warning periodVisual and audio alarm indicationReliable operationMade in the USAModels:7286-PT5:Local door prop alarm module on single gang 2-3/4″ x 4-1/2″ stainless steel wall plate with tri-color LED and 95 dB piezo audible sounder.7286-P5-24:Local door prop alarm module on double gang 4-1/2″ x 4-1/2″ stainless steel plate with tri color LED for visual status 95 dB piezo audible sounder.

Also a form “C” dry contact is supplied that can be used for signaling an independent monitoring system when an authorized door unlock condition occurs.Request to Exit:A single R-E-X input controls the door lock and alarm outputs. The alarm functions are automatically shunted during an authorized unlock sequence. This allows the door prop alarm to be inhibited during an extended authorized door opening.Alarm Shunt:In this mode upon contact closure the unit will not go into either warning or alarm. The rex input still functions as usual.Manual or Automatic Alarm Reset:Typically, the door prop alarm is silenced and reset upon door closing. If no one is available to acknowledge alarms, a timed automatic reset may be engaged to silence the alarm after a preset period of from 0 seconds to 5 minutes, if the door remains in the open position. In the manual reset mode, the audio alarm will sound continuously, even after the door is closed. This manual reset mode requires reset by input from a normally open momentary contact such as a key switch or digital keypad to silence the alarm.Resouces7286 DOOR PROP
