Installation Instructions
1. Choose a mounting location in the control panel within reach of
the leads provided. Use 50/50 water to isopropyl alcohol to
clean the mounting surface. After the surface has dried, remove
protective covering from the tape. Mount unit as shown on
control panel illustration. Route wires to the appropriate
terminals as noted below.
2. Connect 405-05 trigger wires to the fire alarm output terminals.
Observe polarity. [Gray wire to positive (+) and White wire to
negative (-)].
3. Connect 405-05 incoming power wires to the smoke detector
power source. [White-Red to (+) and White-Black to (-)].
4. Connect 405-05 outgoing power wires to the smoke detector
power in terminals. [Red to (+) and Black to (-)].
5. Connect the smoke detector initiating circuit (alarm loop) to the
alarm control.
6. Maintenance: no maintenance is required.
Warning
This polarity reversal device may not be compatible with all
power supervision relays. When using ESL 405 Series
polarity reversal relays on four wire circuits, use the ESL
204 Series power supervision relay at the end of line. Note:
Another option is to use an ESL 449CTE (or CSTE with
Sounder) which incorporates an End-of-Line/Sensitivity
Status Relay Output.
Testing: 405-05
1. Test in accordance with NFPA 72 Chapter 7 Test Methods &
Frequencies, interfacing equipment.
2. To test the 405-05 initiate an alarm with smoke or approved
test method on any detector connected to the control panel
via the 405 relay. In alarm, detectors that have responded to
smoke or test will sound in their distinct alarm patterns.
3. Reset the smoke detectors by removing power to the
detectors.
Note: For two wire smoke detectors, use the ESL 405-01 or
405-03 polarity reversal relay module.
Typical 405-05 Mounting Locations

DPDT Relay Module
For use as a Universal Switch Device
.
Installation Instructions
1. Connect 405-06 trip wires to trigger circuit. Observe
polarity. [Gray to positive (+) and White to negative (-)].
2. Connect the 405-06 DPDT relay contacts as required.
The first set of contacts are:
common red
closed white-red
open white-blue
3. The second set of contacts are:
common black
closed white-black
open blue
4. When fail safe operation is required, wire the relay in the
powered or energized condition.
5. Do not exceed rating of relay.
6. Testing: 405-06
Test unit in accordance with NFPA 72 Chapter 7 Test
Methods and Frequencies, interface equipment.
To test the 405-06, energize the relay coil and confirm the
contacts tranfer.
