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.
