ELM365
Security System Controller
Description
The ELM365 provides all of the logic necessary
for a complete security system in an 8 pin package.
The circuit is capable of monitoring two normally
closed input loops and one normally open panic
circuit, provides a constant level and a pulsing alarm
output, and the logic to drive a status LED.
Internal timers are provided for alarm blocking
during zone entry and exit as well as circuit
resetting, should alarms go unacknowledged.
Debouncing of all of the inputs is also provided
internally, to allow for the direct interfacing to
www.DataSheemt4eUch.acnoimcal switches.
Due to the digital techniques employed, no
external support components are required for any of
the timing functions, resulting in considerable cost
savings over other designs.
Applications
• Home or cottage security systems
• Auto or RV security systems
• Individual zone monitoring in a multizone system
• High or low limit warning alarms
Features
• Low power CMOS design - typically 1mA at 5V
• Wide supply range - 3.0 to 5.5 volt operation
• Simultaneous monitoring of three circuits
• 45 second delay for entry and exit
• Automatic reset of alarm outputs after 5 minutes
• Status LED output driver
• High current drive outputs - up to 25 mA
• Panic input for instant triggering of the alarm
