Morley ZX Loop Driver Card for Morley IAS Protocol

Morley ZX Loop Driver Card for Morley IAS Protocol

The Morley IAS Loop Driver is a plug-in card for use in the ZXa and ZXe intelligent multi protocol fire alarm control panels. This module allows ZXa and ZXe 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.
