The XLEN-R-12 repeater panels have the same, easy to use, controls and indications as the main control panel but mounted in a smaller cabinet. The repeaters are fully functional with ‘Silence’, ‘Resound’ and ‘Reset’ controls, as well as Disable and Test Mode functions. It is also possible to disable the controls for each or all repeater panels to make them passive (indication only). Up to 8 repeater panels can be supported on a system.
Repeater panels are designed to be wired in a fault tolerant (fail safe) loop configuration, from comms A to B and back to the main panel again. This enables repeater panels to still work if there is a break in the cables. If replacing an older system where the existing cabling cannot be configured in a loop as above, it is possible to re-programme the panel back to legacy RS485 circuit comms monitoring. This then allows any topology of comms cabling to be utilised.
The main circuit board has 2, switch –ve, inputs which can be used to sound or pulse the alarms. These inputs can also be re-programmed for use as PSU fault inputs. The internal comms PCB has 6, switch –ve, programmable outputs. Different key types are used for the door lock and the ‘activate controls’ key-switch. It is also possible to enable the controls via a 4 digit code entry if preferred. An eight button keypad is used to control the system and allow access to the function options (unless disabled).
The control panel comprises of a sheet steel enclosure suitable for wall mounting with a hinged, lockable front access door. It can be semi recessed, using a suitable recessing bezel. Cable entry is via 20mm ‘knockouts’ located at the top and rear of the cabinet.
The repeaters are supplied with a 1.5 amp internal power supply module. This module complies with the requirements of EN54-4 : 1988 and provides temperature compensated battery management charging.
