Honeywell MI-DCZME Conventional Zone Interface Module Instruction Manual
Introduction
This manual is intended as a quick reference installation guide.
Please refer to the control panel manufacturers installation manual for
detailed system information.
The Morley series of modules are a family of microprocessor controlled
interface devices permitting the monitoring and/or control of auxiliary
devices.
The MI-DCZME provides an interface between a zone of System Sensor
manufactured conventional type fire detection devices and an intelligent
signaling loop.
A single tri-colour LED indicates the status of the module.
In normal conditions, the LED can be set by command from the control panel to
blink green when the module is polled.
In the case of a fire alarm on the conventional zone, the LED is switched on
constant red by panel command.
If a fault is detected on the conventional zone or the zone supply voltage
drops below 18V, or a fault with the external power supply is signaled, the
LED will blink yellow if enabled on the control panel.
When a short circuit is detected on the loop to either side of the module, the
LED is switched to show a constant yellow light.
This module does not require maintenance.

INSTALLATION
Note: These modules must only be connected to control panels using
compatible proprietary analogue addressable communication protocols for
monitoring and control.
Morley series modules can be mounted in several ways (See Figure 1):
- 1:1 An M200E-SMB custom low profile surface-mounting box. The SMB Base is affixed to mounting surface, and then the module and cover are screwed onto the base using the two screws supplied. Box dimensions: 132mm(H) x 137mm(W) x 40mm(D)
- 1:2 The DIN bracket on top allows mounting onto standard 35mm x 7.5mm “Top Hat” DIN rail inside a control panel or other suitable enclosure. Install and remove as shown in Figure 1:2
Wiring to all series Morley modules is via plug in type terminals capable of supporting conductors up to 2.5mm²
CAUTION
Disconnect loop power before installing modules or sensors.
The module address is selected by means of rotary decade address switches (see Figure 3). A screwdriver should be used to rotate the wheels to select the desired address, either from the front or the top of the module.
Note: The number of addresses available will be dependent on panel
capability, check the panel documentation for information on this.
Short Circuit Isolators
All Morley series modules are provided with short circuit monitoring and
isolators on the intelligent loop.
If required the isolators may be wired out of the loop to facilitate the use
of the modules on high current loaded loops, for example if sounders are used.
To achieve this, the loop out positive should be wired to terminal 5 rather
than terminal 2. See Figure 2 for details.
CAUTION
Electrostatic Sensitive Device
Observe precautions when handling and making connections
