The Morley IAS Loop Driver is a plug-in card for use in the ZX series intelligent multi protocol fire alarm control panels. This module allows ZX series control panels to support input/output points from Morley-IAS analogue addressable devices: • Smoke Sensors (Ionisation and optical) • Heat Sensors • Monitor Modules • Control Modules • Isolator Modules • Conventional Zone • Addressable manual call points & pull stations • Addressable sounders The plug-in card provides power for and handles communications to the addressable devices. The loop driver continuously monitors the analogue values of all sensors and displays this value on the panel as a percentage of the alarm threshold value. Both the alarm and pre-alarm threshold levels can be adjusted from the control panel if required. Up to 198 devices (99 sensors and 99 modules) can be connected to a single loop driver. Each device has two rotary decade switches to allow a unique address to be selected.

• Compatible with ZX series intelligent multi protocol fire alarm control panels • Provides one class-A or class-B loop • Supports Morley-IAS analogue addressable sensors and modules • Plug-in connection • Double address detection
