A common installation would be a back office door in a restaurant or retail shop.
These doors are not easy to see from the main work area and the horns provide a good method of monitoring their use.
Door contacts are required to activate the horns. The contacts signal when the door is open and the horn should sound.
Think of Locknetics horns as an ''add-on'' to a security system.
These systems keep a door locked unless someone has authorized access.
The horns are designed to let you know when someone uses a door without authorized access.
Mainly, this means a person exiting a door that should not be exiting.
It's good to place the horn near the door so it is obvious to anyone that using the door will cause a lot of comotion.
When using the stobe option, the unit must be place in the line of sight with the main work area to do much good.
The ''L'' latching option is rarely used as it is designed to run a secondary lock from the 1910.
A typical installation would have the power supply control the locking and unlocking of a door.
If you have a secondary lock, (mag lock or electric strike) you may run this from the 1910.
The unlock time of the secondary lock would be controled by the timer on the 1910.
