E-RLY Analog Contact Relay Module
Installation Sheet

Description

The E-RLY Analog Contact Relay Module is an analog
addressable device that provides one Form C dry relay
contact. It can also be configured to provide polarity reversal of
its output. The module can be used to control external
appliances or shut down equipment.

The device address is set using the two rotary switches located
on the front of the module. One device address is required.

The module is wired according to its operation, as shown in
“Wiring” on page 2. The module is configured to operate as a
relay nonsilence device type from the factory. It can function as
either a control relay or polarity reversal relay, depending on
how it is wired.

Control relay function: Addressable device that provides one
Form C dry relay contact. The system firmware ensures that
the relay is in the proper state when powered up. Upon
command from the control panel, the E-RLY relay energizes.

Polarity reversal relay function: Addressable device that
provides polarity reversal of its output. The system firmware
ensures that the relay is in the proper state when powered up.
Upon command from the control panel, the E-RLY relay
energizes, reversing the polarity of its output.

Note: Additional device types are available through front panel
programming or the configuration utility. Refer to the applicable
control panel technical reference manual.

LED operation

The module provides a bicolor LED that shows its status.
Normal: Green LED flashes
Active: Red LED flashes

Installation

WARNING: Connecting a device that exceeds this module’s

pilot duty contact ratings may cause activation failure. This
module does not support capacitive loads. See “Specifications”
on page 4 for contact ratings.

Notes

• The module is shipped from the factory as an assembled
unit; it contains no user-serviceable parts and should not
be disassembled.

• This module will not operate without electrical power. As
fires frequently cause power interruption, you should
discuss further safeguards with your local fire protection
specialist.

• This module does not support conventional smoke
detectors.

• Install the module within the same room as the device it is
controlling.

To install the module:

1. Verify that all field wiring is free of opens, shorts, and
ground faults.

2. Wire the module in accordance with “Wiring” on page 2.

3. Set the module address as follows:
Use a screwdriver to adjust the two rotary switches on the

front of the module. Set the TENS rotary switch (0 through

12) for the 10s and 100s digit and the ONES rotary switch
for the 0 through 9 digit. For example: device address 21,
set the TENS rotary switch to 2 and set the ONES rotary
switch to 1.

Refer to “Specifications” on page 4 for available address
numbers.

4. Mount the module on the electrical box using screws
provided with the electrical box. See Figure 2.

5. Mount the wall plate on the module using #4-24 x
1/2 self-tapping screws.

• Only one conductor per terminal.

• The signaling line circuit (SLC) circuit is pow er-limited and
supervised.

• Refer to the panel documentation for SLC wiring
specifications.

To wire the module:

1. Verify that all field wiring is free of opens, shorts, and
ground faults.

2. Make all wiring connections using Figure 3 or Figure 4
according to the desired function. Observe polarity of the
wires as shown in the diagrams.

Wiring

Wire in accordance with applicable requirements of the latest
editions of the local codes and standards and the local
authority having jurisdiction.

Note: When stripping wire ends, exposing more wire may

cause a ground fault; exposing less wire may result in a faulty
connection.

Strip 1/4 in. (about 6 mm) from the ends of all w ir es that
connect to the terminal block of the module.
