DTK-240X12 (240VAC 20A + 12 Low Voltage Circuit Series Surge Protective Device)
Read All Instructions Before Beginning Installation!
CAUTION: Risk of Electric Shock - Only intended for installation in accordance with
National Electric Code, ANSI/NFPA-70, Article 398.
Warning: Turn power off at the main circuit breaker panel before beginning install.
Note: Connect this device in series between the 240VAC power supply and the load that requires
protection. Use 12 AWG Stranded, Cu only conductors with a 3/8” strip length when terminating
the wires at the power lugs. The conductors used to connect the SPD, to the supply or buss and to
ground, shall not be any longer than necessary and shall avoid unnecessary bends.
1. Remove (4) screws securing the cover, save screws.
2. Remove cover.
3. Connect a Ground (green or bare conductor) to the EARTH lug at the LINE side.
4. Connect the Neutral (white conductor) supply wire to the NEUT lug at the LINE side..
5. Connect the Phase (black conductor) supply wire to the LINE IN lug at the LINE side.
6. Connect the Ground, Neutral and Phase wires from the LOAD side to the control panel, or your
equipment’s AC inputs.
Note: Tightening torque for the 240VAC power connections is 20 in-lb.
7. Use 3/4” conduit fittings for the AC circuit and a 1/2” conduit fitting for dry contacts. Best practice
dictates the use of separate conduit feeds to isolate the unprotected “LINE” wiring from protected
“LOAD” wiring
8. After all connections have been made and no hazards exist, proceed to the Low Voltage Surge
Module Wiring Diagram.

DTK-2MHLPXXB, DTK-2MHLPXXF (2-Pair Modular Hybrid Line Protector)
Notes: Connect this device in series between the field wiring and the control panel supply wiring.
• These Low Voltage protection circuits are equipped with a removable plug and header assembly. Simply remove the plug from the
header, terminate your wires, then replace the plug making sure it seats and snaps into place.
•There are up to 6 positions for surge modules available for protection of any combination of Dialer Circuit, SLC (Signaling),
IDC (Initiating), PIV (Valve) or NAC (Notifying) circuits. Each module will protect 2 pairs or circuits of the same voltage.
•All modules have been factory pre-wired for ground. It is not necessary to make any additional ground connections.
•Allow for sufficient reaction time by providing a minimum of 3 wire feet between the DTK-240X12 and the alarm panel inputs.
•Use separate conduit feeds to isolate the unprotected “INPUT” wiring from the protected “OUTPUT” wiring.
•Use appropriately sized conduit fittings and conduit (not included).

(Wiring Diagram-Low Voltage Surge Modules Without Dry Contact Circuit)

DTK-DF240M
(240VAC Surge Module Installation)
The DTK-240X12 is a series connected Surge Protective Device, for 240VAC power plus up to 12
individual low voltage circuits, with a replaceable surge module for the 240VAC power and every
2-Pairs of low voltage circuits. The LED indicators on the top face of the DTK-DF240M surge
module provide power, ground and surge module health status. When the DTK-DF240M surge
module has gone end of life, the large “REPLACE” RED LED will illuminate and the “GOOD”
Green LED will turn off. Also, the audible alarm will sound to provide an extra alert to indicate
the surge module’s health. To silence the alarm, remove the dead module and replace it with a
new, unused module. If a new module is not available, the alarm can be silenced by pressing the
tactile switch, located at the end of the enclosure, into BYPASS mode for 24 hours. When a new
DTK-DF240M surge module is installed, the audible alarm will be cancelled. The red polarizing
keys insure that the correct voltage module will mate with its correct base.
WARNING: When the DTK-DF240M module has gone end of life, or is missing, the base is
susceptible to damage from surge energy. Make sure you always have a spare module
available. No substitutions shall be permitted.

Remove the slide cover from the low voltage surge modules compartment. Insert the appropriate
low voltage surge module into the corresponding position according to your connection circuits.
When a DTK-2MHTP tele-communications surge module has expired (gone end of life), there will
be interference or an open circuit to the control panel, indicating the circuit requires service.
When a DTK-2MHLPxxB low voltage surge module has expired (gone end of life), there will be a
ground fault indicating the circuit requires service.
When a DTK-2MHLPxxF* low voltage surge module has expired (gone end of life), there will be an
open circuit, indicating the circuit requires service. *Do not use with PIV or NAC circuits.
After all modules are inserted, replace slide cover and fasten.
Restore power and verify correct operation.
