The Honeywell Morley-IAS ZXr-A (ZXRA) Active Repeater Panel (manufacturer part number 709-601-001) is engineered for full integration across all Morley-IAS intelligent multi-protocol fire alarm control panels, including the Morley-IAS ZX series panels. As an active remote unit, it replicates the operational status and primary operator controls of the central panel—including System Reset, Accept, Mute, Silence Alarms, and diagnostic Self Test—via an integral key-operated 'Access Enable' keyswitch.
Morley-IAS Control Panel Compatibility
The ZXr-A active repeater functions as a direct remote node for the following system architectures:
- Morley-IAS Intelligent Multi-Protocol Panels: Engineered for full compatibility with all Morley-IAS multi-protocol intelligent fire alarm control panels, operating as an active control and status display terminal.
- ZX Series Fire Alarm Control Panels: Interfaces seamlessly with ZX series control units, duplicating the primary panel's operational state via the 80-character backlit alphanumeric liquid crystal display and 7 LED status indicators.
- Supervised Cabling Integrity: The host ZX fire alarm control panel actively monitors and supervises the transmission link to each connected repeater. Any break, short circuit, or signal interruption is instantly flagged as a communication loss condition on both the repeater and the main panel.
RS485 Peripheral Bus Architecture and Networking Limits
Data transmission between the central Morley-IAS fire alarm control panel and distributed repeater units is established through a dedicated RS485 peripheral data port. Key networking parameters include:
- Bus Standard: Industrial RS485 serial communication protocol utilizing the peripheral data bus.
- Network Capacity: Accommodates up to a maximum of 31 active repeaters on a single RS485 peripheral data port loop.
- Bus Failure Annunciation: In the event of data line interruption between the main panel and repeater, the unit triggers an alert and illuminates a dedicated yellow 'Communications Loss' LED alongside standard panel fault indicators.
- Field Wiring Terminals: Equipped with industrial screw terminals that support field wiring up to a maximum cable cross-section of 2.5 mm².
Power Supply and Operating Voltage Compatibility
The ZXr-A active repeater requires nominal +24 Vdc auxiliary operating power and can be powered via multiple field-approved wiring topologies:
| Parameter | Specification / Compatibility Range |
|---|---|
| Operating Voltage Range | 18 Vdc to 32 Vdc (+24 Vdc nominal) |
| Quiescent Current Consumption | 90 mA |
| Alarm Current Consumption | 120 mA |
| Power Source Compatibility | Panel auxiliary +24 Vdc DC output or external regulated +24 Vdc power supply unit |
| Operating Temperature Range | +5°C to +45°C |
| Operating Humidity Range | 5% to 95% RH (non-condensing) |
Compatible Hardware Modules and System Accessories
To support various mounting arrangements and interface requirements across industrial and commercial facilities, the ZXr-A repeater is compatible with verified Morley-IAS system accessories:
- RS485 Communication Module (Part Number 795-004-001): Dedicated interface card installed at the Morley-IAS fire alarm control panel to drive the peripheral serial data loop.
