Interesting Applications

Recordable voice sirens are one of my favorites. The Elk 120 is a littlepricey, but you can do some neat stuff with it with its 4 voice channels and4 inputs. I have one at a school that blasts a message throughout thebuilding whenever anybody arms the alarm as a warning. It has a differentmessage that plays through out whenever somebody enters the building aswell. Of course it has the typical "burglary burglary burglary" messagethat plays when the alarm goes off as well.Since I set it up they have not had a single entry or exit error."The alarm has been activated. Exit the building immediatley. If you needto stay in the building contact somebody with a valid alarm code and disarmthe alarm" or something like that."The alarm system is active. You must disarm now."I have another application where a business has deliveries dropped off inlockable containers in their side yard. The carrier puts the delivery inthe container and then locks the container. This requires them to leave aside gate unlocked. We set up an armored contact on the gate. It trips atrigger output on their alarm that plays a custom message. "Deliverydrivers ONLY beyond this point. ALL OTHERS ARE TRESSPASSING. You are beingvideo taped. Tresspassers will be prosecuted." Then we set the alarm up topage the business owner whenever the gate is opened. It is a great stopgap. System. We also use the trigger output to trip a relay which activatesthe alarm input on their digital video recorder to switch that camera toreal time whenever that gate is opened. Made for an interesting interactionwhen a delivery driver tried to lie about making a delivery."Golly, there is no video of you in that area, and gee... you never openedthe gate. Maybe you should double check your truck."Bob La Londe*** Free account sponsored by ****** Encrypt your Internet usage with a free VPN account from ***

Old age, bad eye sight and can't remember yesterday, so what was it we were talking about.

Heh... right. I have a feeling you've got a mind like a steel trap. How else are you going to remember how to program a Napco panel from the kepad without a manual? :-)

Mighty decent of you. I can use some help with "better search engine positioning". ;-)

Notice how Robert *still* hasn't answered Bob's question? I wonder if he has him plonked now too!!
