TORK

Lighting Reactivation Switch

Model: LDSH, LDSH-A

INSTALLATION AND USER’S GUIDE

FUNCTION & DESCRIPTION

The Lighting Delay Switch is an accessory to any

TORK maintained contact time switch and is used to

extend the time on of lighting, HVAC, and other

main building loads after the time switch turns OFF.

An auxiliary contact closes, turning on a user select-

ed signal device (i.e. bell, horn, light, or other warn-

ing device), which turns off at the end of the user

selected 4 second, 1 minute or 5 minute period.

Remote momentary ON/OFF push button switch-

es can be connected to the designated terminal of

the Lighting Delay Switch using low voltage #18 -

22 AWG twisted pair wires. Pressing the remote

ON button momentarily during a 1 or 5 minute

warning period will extend the time on (main load)

for a user selectable 1/2 hour, 1 hour, 1-1/2 hour,

2 hours, 6 hours, 9 hours, or 12 hours. At the end

of the extended time the user selected signal

device will again turn on, allowing personnel to

repeat another 1/2 - 12 hour extension of the main

load if necessary. Pressing the remote OFF button

for 3 to 4 seconds will terminate the extension of

time for the main load, and turn on the auxiliary

warning circuit. The warning circuit will turn OFF

after the 4 second, 1 minute or 5 minute period.

The main load will turn off after 1 or 5 minutes

(user selectable).

When starting up after a power failure (if time

switch is not ON), the main load will be turned ON

for 10 minutes. At the end of the 10 minute period,

the warning circuit will turn on. The main load will

remain ON for the 1 or 5 minute warning period. If

an extension of time is required for the main load,

press the remote ON button momentarily. The

auxiliary warning circuit will turn off, and the main

load will remain on for an additional 1/2 - 12 hour

extension of time.

This unit is ideally suited to meet Energy

Conservation construction codes relative to con-

trolled lighting after hours and assures building

loads will go OFF after personnel (i.e. cleaning-

staff working after hours) leave the building.

NOTE:

1. Multiple remote momentary push buttons may

be wired to the same terminals for access from dif-

ferent locations.

2. The Lighting Delay Switch can be operated as

a stand alone control using remote ON/OFF

momentary push-buttons.

3. If time of day control is also required, see

wiring diagram for time switch interface.

A. Pressing the remote ON momentary push-but-

ton while the time switch is ON will start the

internal timer of the Lighting Delay Switch, but

will have no immediate impact on the main load.

When the time switch turns OFF, the load will

remain ON for the duration left on the LDSH.

B. Pressing the remote OFF push button for 3 to 4

seconds while the time switch is ON will termi-

nate the internal timer of the Lighting Delay

Switch, but will have no impact on the main

load which will remain ON. When the time

switch turns OFF, the load will turn OFF after

the warning period.

INSTALLATION PROCEDURE

Step 1:

Model LDSH only.

Remove the unit from the

plastic track. Mount the plastic track with provided

hardware only. Do not use other hardware. Snap

the unit back into the track.

Step 2:

Before wiring, power to this unit, the time switch,

and the equipment it controls must be turned off

at the main panel. Wire the unit according to the

appropriate wiring diagrams provided. Be sure to

follow local and all other codes.

Step 3:

Set all switches #1, 2, 3, and 4 to the ON position

for test. This will accelerate the complete opera-

tion of the unit to under 1 minute, allowing a check

of the wiring and the functions.

Step 4:

Set the extended time delay for the main load to

the appropriate time by adjusting switch #1, 2, and

3. See table for desired timing.
