  • Page 109 LO-2 External Override Capabilities Two Class II low voltage manual override inputs, one for each relay output, are provided for override capabilities. These inputs directly control the lighting relays, independent of any schedule or program. Wall switches, occupancy sensors, or a combination of both may be wired to these inputs.
  • Page 110 Externally mounted sensors such as proximity sensors require power to operate as well. The LO-2 module provides a connection for these devices to receive half wave rectified 24V power as indicated below: 24 VDC (half-wave rectified AC) to External Sensors 24 VAC RECT Andover Controls Technical Manuals Online! - http://www.tech-man.com...
  • Page 111 LO-2 Relays The GE relays are mounted on an external bracket with integral connecting cable. This cable terminates in a five-pin Molex-style connector that mates easily with one of the two provided at the bottom of the module as shown below: The connector is keyed so that it locks into place after insertion.

The door’s operating mode can even be changed based on time-of-day or other events for optimum flexibility through Andover Controls’ easy-to-use Plain English programming language. Each keypad can also permit entry of a duress alarm code that can initiate an alarm sequence at any AC-1 controller or at the Continuum workstation.
  • Page 123 AC-1 Connecting a Reader/Keypad Reader/Keypad Inputs The AC-1 includes a full interface to a single Wiegand (AC-1) or an ABA (AC-1-ABA) access card reader. The modules were designed to allow keypads that have similar interfaces (Wiegand or ABA) to be connected in place of a reader. Integral reader/keypad units are also supported.

  • Page 125 AC-1 Connecting Inputs All AC-1 and AC-1-ABA inputs are supervisory inputs. The following drawings depict the six types of supervisory inputs that exist—three normally closed and three normally open types. After the drawings, there is an explanation of which types are recommended for access control installations.
  • Page 126 Shorting the input causes it to look like a normal “door closed” condition. In this case the door could be forced open and the system would not detect the change in condition. Andover Controls Technical Manuals Online! - http://www.tech-man.com...
  • Page 127 AC-1 Normally Closed Supervisory Inputs NC Series Parallel With this type of input wiring, two external resistors are added to the input, one in series and the other in parallel. When the door switch is closed (normal position) the door is assumed to be closed.
  • Page 128 Shorting the input causes a zero ohm reading which should result in an error condition. Cutting the wire causes it to look like a normal “door closed” condition. In this case the door could be forced open and the system would not detect the change in condition. Andover Controls Technical Manuals Online! - http://www.tech-man.com...
  • Page 129 AC-1 Normally Open Supervisory Inputs NO Parallel With this type of input wiring, a resistor is placed in parallel (across) with the input. When the door switch is open (normal position) the door is assumed to be closed. The circuit presents a reading of the external resistance at the input.

  • Page 131 AC-1 Recommended Input Circuits We recommend NO Parallel and NO Series and Parallel types for access control installations. The following pages explain how to wire these types of inputs for door switches and motion detectors. Wiring Door Switches There are three supervisory inputs for door switches.
