NAPCO GEMC-EZM8 Zone Expansion Module Installation Instructions

Description

The GEMC-EZM8 Zone Expansion Module expands the capacity of NAPCO's GEMC-Series control panels. Each module provides up to 8 additional zones, configurable as either 4 or 8 zones per module. Multiple GEMC-EZM8 modules can be combined to meet the required number of zones for the GEMC-Series control panel. Refer to the GEMC-Series control panel installation instructions (WI1653) for specific wiring requirements.

Specifications

• Input Power: 12.5 - 7.5VDC, 60mA
• Zone Loop Current: 4.7mA nominal, 5.5mA when shorted
• Maximum Zone Loop Resistance: 300 ohms
• End of Line Resistor (EOLR): 2.2K (UL Listed part number EOL2.2K required for Fire applications)
• PGM Output: 5mA, 12V (Active low). For power-limited circuits less than 14VDC. Use only in Burglary applications.
• Ground Faults Detected: 1.25K to ground or less.

Wiring

Wire the expansion zones to the module and the module to the control panel using 12-22AWG wire. Install end-of-line resistors (EOLR) on all zones, even if a zone is not used. Note: Adding Zone Expansion Modules reduces the current available from the control panel's Auxiliary Power Output terminals by 60mA.

Diagram Descriptions

Configuration and Programming

Tamper Functionality

If the module cover is removed or the module is detached from its mounting, the keypad sounder will pulse, and the display will indicate a zone/module tamper condition along with the module number. Pressing RESET silences the sounder. Note: The EZM tamper function does not operate when the module is used in a GEMC-Series control panel Fire system or Combination Fire/Burglary system if the GEMC-EZM8 is programmed as a 4 Zone Fire type or 8 Zone Fire type.

Loop Response

Loop response times for Zones 1 through 8 are programmed in the control panel. The default response time for all expansion zones is 750mS. To reduce the response time of zones 1 through 4 of the EZM Module to 50mS, install the Loop Response Jumper (Jumper #8: ON = 50mS; OFF = 750mS). To revert to the normal 750mS response time, remove the jumper. Refer to the Wiring Diagram for placement. DO NOT ENABLE THIS FEATURE IN UL INSTALLATIONS.

Status LED

The Status LED indicates the condition of the zone module:

• OFF: Control Panel has no power applied.
• ON Steady: Control Panel has power applied, but the panel is not polling the module. This can occur if: the panel is in "CONFIG" mode, the panel is not programmed to poll the module's address, or the green wire (GRN) is not connected correctly.
• PULSES: Indicates the EZM groups being polled.
  • Once slowly: The first EZM group (base address) is polled.
  • Once then twice sequentially: The first and second EZM groups are polled.
  • 1, 2, 3, 4 sequentially: The first, second, third, and fourth groups are polled.

Important Wiring Methods

Proper wiring techniques are crucial for reliable operation. The following methods are recommended for terminal blocks:

Use insulated wire for pigtails and secure conductors firmly with appropriate connectors for the number and gauge of wires used.
