ACT 4201
4 Zone Opto-Isolator

The ACT 4201 is designed to prevent false alarms by optical isolating troublesome zones from the control panel. Zone and tamper cables running close to mains, telephone and computer cabling can pick up induced EMI/RFI signals. This can play havoc with the microprocessor control equipment, causing unexplained false alarms and system malfunctions.

Passing normally closed circuit wires through an opto-isolator, totally isolates alarm cabling from the control panel inputs. Long circuit cables affected by nearby lightning can also be isolated this way.

Features

• Prevents false alarms on up to 4 normally closed alarm circuits by isolating the circuit wiring from the control panel zone or tamper input circuit
• Particularly beneficial on alarm takeovers when updating control equipment, but retaining alarm circuit wiring
