PAD100-SLCE Addressable Loop Expander
NOTICE TO THE INSTALLER
- This manual provides an overview and the installation instructions for the PAD100-SLCE module. This module is only compatible with addressable fire systems that utilize the PAD Addressable Protocol.
- 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 Signaling Line Circuit Expander allows up to thirty one additional loops. Each loop adds 127 addressable sensors or modules in any combination. The PAD100-SLCE may be configured for Class A or Class B wiring without the need for additional modules. The PAD100-SLCE communicates with the control panel via the 4-wire RS-485 communication bus. The loop adder is mounted in either the control panel cabinet, the intelligent power supply, AE-2, AE-8 or the AE-14 expander cabinet. Each card is mounted to the exclusive Stacker Bracket for secure and accessible mounting
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:
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.
Before connecting a device to
the RS-485 connection, take the following precautions to prevent potential
damage to the RS-485 connection or device.
- Power to the RS-485 is removed.
- Field wiring on module is correctly installed.
- Field wiring has no open or short circuits.

Installation
The PAD100-SLCE is connected to the listed control panels using a four wire
RS-485 connection. This connection is power limited and supervised. The
PAD100-SLCE can be installed in the AE-2, AE-8, AE-14 expansion enclosure or
inside the large listed fire alarm control panel enclosure using the supplied
bracket. The wiring diagrams shown below illustrate how to wire a PAD100-SLCE
as Class B and Class A.
Notes:
- RS-485 wiring style supports the Class A and Class B.
- RS-485 wiring is power limited and supervised.
- All wiring is between #12 (max.) and #22 (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.
