The Honeywell Morley-IAS ZXr-A (part number 709-601-001) is an active remote control and display repeater engineered to duplicate system status and control capabilities across critical building management locations. Connected to Morley-IAS intelligent multi-protocol fire alarm control panels via an RS485 peripheral data port, the ZXr-A supports multi-node configurations of up to 31 active repeaters on a single peripheral network loop. By operating on a nominal +24 Vdc supply (18 Vdc to 32 Vdc range) with low current demand (90 mA quiescent, 120 mA in alarm), the repeater provides versatile secondary command capabilities across industrial, commercial, and healthcare infrastructures.
24/7 Security Control Rooms and Command Centers
Central security control rooms require immediate, actionable intelligence during life safety events without personnel having to travel to the main fire panel room. Deployed at monitoring consoles, the ZXr-A provides real-time event updates via its 80-character backlit alphanumeric liquid crystal display and 7 dedicated LED status indicators (Fire, Fault, Disables, Accepted, Silenced, Power, and Communications Loss).
Authorized operators can use the key-operated 'Access Enable' switch to unlock essential intervention push buttons, allowing security staff to execute Accept, Mute, Silence Alarms, and System Reset routines directly from the desk console. If peripheral loop continuity is compromised, the main ZX panel's supervised RS485 data link triggers an alert on both the panel and the repeater's Communications Loss LED, preserving overall situational awareness.
Primary Building Entrances and Fire Brigade Access Foyers
During emergency dispatch operations, responding fire authorities require immediate visibility into fire alarm zones upon entering a building. Installing the ZXr-A at primary entry foyers or security gatehouses gives responders full visibility into incident details on the 80-character LCD before they proceed further into the facility.
Because the unit weighs approximately 1.7 kg and features compact dimensions (165 mm height x 254 mm width x 50 mm depth), it fits into reception desks, entrance vestibules, and riser lobbies. Field wiring is simplified by terminals accommodating up to 2.5 mm² cable cross sections, allowing robust cabling runs suited for long-distance RS485 communication.
Healthcare Facilities and Nurse Stations
In hospital wards, clinical environments, and residential care complexes, the ZXr-A serves as an essential remote interface at staffed nurse stations. Personnel receive instantaneous, clear-text event descriptions on the backlit display while retaining local mute and accept capabilities to manage audible local buzzers during verification procedures. The integrated key-switch ensures patient-accessible areas do not risk accidental or unauthorized tampering with fire system controls.
Deployment Architecture Overview
- Primary Connection Interface: Two-wire RS485 peripheral data port linked directly to Morley-IAS ZX series multi-protocol panels.
- System Capacity: Up to 31 active repeaters per peripheral data network loop.
- Power Sourcing Options: Powered via the auxiliary DC output of the main fire panel or an external +24 Vdc field power supply.
- Environmental Range: Rated for indoor operating temperatures between +5°C and +45°C with 5% to 95% non-condensing relative humidity.
- Routine Testing: Integral operator-initiated self-test diagnostic mode checks control buttons, key-switch contact, and display indicators without initiating facility-wide fire signals.
