Always know when you doors have been left open
Allowing a door to be used, but not left in the open position for extended time periods is becoming more common. Detex created the EAX-300, to address this issue and maintain security and/or lower HVAC costs by conserving energy lost through open doors.
A common example of a door that requires the ability to be opened from the inside but which should not be left in the open position is one that exits from a warehouse to an outdoor break or smoking area. In days gone by, such a door would be propped open with a rock, piece of wood or any available object. This allowed employees to re-enter the building without the use of a key or access control credential. Unfortunately unscrupulous people will prop a secure door open to allow them unauthorized access from the outside when the building is supposed to be secure.
Student residence buildings also require a method of ensuring the closure of exterior doors. Residents will often exit through exterior stairwell doors when it allows for a shortcut. The problem arises when the stairwell doors are propped open to allow re-entry through the same opening, thereby eliminating the security provided by the access control system on the main entry doors. Knowing that these doors are often propped open, non-residents can also gain entry which compromises the safety of young people living there.
Door prop/exit alarm options
The Detex EAX-300 is a simple to install, battery operated alarm that will sound if the door is left open longer than its pre-set time. Simply reclosing the door will silence and reset the alarm. The allowable open time can be adjusted from 1 second to 4 minutes and comes pre-set at 15 seconds.
Optional features include:
- External door position switch connections for monitoring multiple doors.
- An internal door position switch is included as standard.
- KS – Key Stop, prevents the arming/disarming key from permanently disarming the alarm. When the key is removed the unit is always armed.
- SI – Status Indicator On provides visual indication that the unit is armed. This can be turned on in the field as well.
- Weatherized – allows alarm to be installed on exterior gates or doors that are exposed to inclement weather.
