EN | 7 LTC 8770 Series | Instruction Manual | Unpacking 1 UNPACKING 3 Unpack carefully. This electronic equipment should be handled with care. Check for the following items: • Verify the Relay Unit model number, LTC 8770/60 or LTC 8770/50 • Four 12-pin relay screw terminal connectors • One 3-pin biphase screw terminal connector If the item appears to have been damaged in shipment, replace it properly in its carton and notify the shipper.
EN | 8 LTC 8770 Series | Instruction Manual | Installation 4.3 Biphase Control Code Input The biphase control code input connection is made to the 3-pin screw terminal connector located on the rear of the unit. This is the communications port where commands are received using the proprietary biphase protocol. The CODE_IN +, SHIELD, and CODE_IN – wires are connected to the device generating the biphase code (such as the output from an LTC 8568 Series Signal Distribution unit).
EN | 9 LTC 8770 Series | Instruction Manual | Installation Remove the cover following the directions below, later paragraphs describe in detail each DIP switch function. Locate all DIP switch positions on the circuit board using FIGURE 1. Set the DIP switches to obtain the desired operation, then re-install the cover. 4.5 Selecting Modes of Operation Switches S105-1 through S105-3 determine the mode of operation for the unit. There are seven modes of operation.
EN | 10 LTC 8770 Series | Instruction Manual | Installation 4.7 Monitor Number Thumb-wheel switches S101, S102, S103, and S104 collectively make up and determine the monitor number selection. The number dialed on these switches indicates the monitor number to respond to when commands are sent with monitor information. The monitor number is read once on power-up and the value of the number is read conventionally.
EN | 11 LTC 8770 Series | Instruction Manual | Operation 5 OPERATION Once the application has been determined, the operational setup of the LTC 8770 must be implemented via DIP switches. BEFORE connecting power to the unit, the internal DIP switches should be set for the desired operation. The DIP switches are read by the unit on power-up and should be only changed when the system is unplugged and the power is OFF. The Relay Unit has two main operating modes, and several sub-modes.
EN | 12 LTC 8770 Series | Instruction Manual | Operation It is also possible to control the relays of a LTC 8770 unit when it is connected to an Allegiant Series matrix switcher, by using Allegiant Command Console Language (CCL) commands. Refer to the Allegiant CCL Manual (available for download from www.boschsecuritysystems.com) for complete details on controlling an Allegiant switcher using ASCIIbased commands from an external device.
EN | 13 LTC 8770 Series | Instruction Manual | Operation This mode responds only to cameras in an alarm condition (alarm cameras). The physical relay whose Logical Relay Number corresponds to the alarm camera being displayed on this selected monitor will activate indefinitely. If the monitor displays a camera not in an alarm condition (non-alarm camera), no relay is activated. This mode is basically identical to Mode 3, except that it only responds to Cameras in Alarm.
