PLAN12005 - INTRUSION ALARM SYSTEM
This is a completely self-contained proximity burglar alarm system. This system requires no installation wiring. You just set it up in a room, plug it in and make one adjustment. Anyone entering the room will cause an alarm to sound and a radio signal to begin sending an alerting signal to you so you know, even at a distance, that someone has entered the room. Unplugging the alarm will not stop it. Only you can turn it off.
PLAN12007 - PHOTO CELL ALARM CONTROL
This circuit can be used to control an alarm or may be used as an announcer, counter control, etc. No special light source is needed. Placed in a room, a person passing will change the amount of light falling on the photo cells and set off the alarm.
PLAN12008 - FIRE ALARM CONTROL
The heat sensitive transistor of this fire alarm control circuit reacts to the increase in temperature which sets off the alarm. When the transistor reaches a certain temperature it will conduct, causing a relay to close, setting off the alarm.
PLAN12009 - DOOR KNOB ALARM
An ideal intrusion detector for the traveler to hang on his motel doorknob. Anyone touching the knob on the outside will set off a loud piercing alarm. Put one on both front and rear doors at home.
