POTTER LED-16 LED Annunciator Instruction Manual

NOTICE TO THE INSTALLER

This manual provides an overview and the installation instructions for the LED-16 module.

All terminals are power limited and should be wired in accordance with the requirements of NFPA 70 (NEC) and NFPA 72 (National Fire Alarm Code). Failure to follow the wiring diagrams in the following pages will cause the system to not operate as intended. For further information, refer to the control panel installation instructions.

The module shall only be installed with listed control panels. Refer to the control panel installation manual for proper system operation.

Description

The LED-16 is a LED remote annunciator. LED-16 communicates using a RS-485 connection to the main panel providing zone specific indication of Alarm Supervisory, and Trouble conditions. The module mounts on either a 4″ square or double gang box.

The LED-16 features 2 slide-in labels allowing each of the 16 zones to be customized for any application. It can be mounted on a single gang electrical box or a four-square electrical box. The annunciator utilizes a sheet metal enclosure secured with a Potter lock

Setting the Address

Each P-Link device has a five (5) position dip switch which is used to program the device address ranging from one (1) to thirty-one (31). The table below may be used to set dip switches when addressing any P-Link module:

Figure 1. Dip Switch Settings Table (Addresses 1–31)

Table

Note: Each “gray” box indicates that the dip switch is “On,” and each “white” box indicates “Off.”

The examples shown below illustrate a P-Link’s dip switch settings: the 1st example shows a P-Link module not addressed where all dip switch settings are in the default “Off” position, the 2nd illustrates an addressed P-Link module via the dip switch settings.

Figure 2. Examples of P-Link Module Showing Default Dip Switch Setting (Unaddressed) & Addressed

All dip switches are shown in the “Off” position.

Example shows this P-Link module address = 10. Dip switches #2 & 8 are in the “On” position.

Before connecting a device to the RS-485, take the following precautions to prevent potential damage to the RS-485 connection or P-Link or device.

Wiring Diagram

Notes:

RS-485 supports the Class A, and Class B.
RS-485 connection is power limited and supervised.
All wiring is between #12 (max.) and #18 (min.).
Wire Preparation – Strip all wires 1/4 inch from their edges as shown here:
- Stripping too much insulation may cause a ground fault.
- Stripping too little may cause a poor connection and subsequently an open circuit.

These instructions do not purport to cover all the details or variations in the equipment described, nor provide for every possible contingency to be met in connection with installation, operation and maintenance.
