Winland Electronics Temp Alert TA­2HL Installation & Owner's Manual

TEMP˚ ALERT
Model TA­2HL
Part No. M­001­0100
Installation / Owners Manual
Introduction
Thank you for your purchase of the Winland Temp˚ Alert
and low temperature limits are critical. Temp˚ Alert
low temperature alarm signals. This unique feature enables you to instantly identify whether your facility being monitored has a high or low temperature
condition.
Simply select an acceptable temperature range by setting the adjustable high and low limit stops. If temperature in the monitored area either rises or falls to the
limit stops, the temperature indicator will contact one of the limit stops. This completes the circuit and provides you with a dry contact alarm signal. The TA­2HL
contacts are normally open dry contacts rated at 50 mA at 12 VDC. This output can be used to activate alarm systems, telephone dialers, or other remote
®
warning devices. Temp˚ Alert is the ideal addition for any security system.
The package you purchased should contain:
®
· Temp˚ Alert unit with 15 foot (4.57 m) connection cable
Two mounting screws and two plastic wall anchors
·
· Mounting template (attached to the manual)
Location
In specifying the location and number of Temp˚ Alerts
building already has an energy management system, an easy rule of thumb to follow is to install a Temp˚ Alert
a wall or other vertical surface in the area where temperature is to be monitored. Make sure it is well clear of windows, doors, or heat sources that could cause
an inaccurate reading of air temperature. When protecting a building against freeze damage, always install at least one Temp˚ Alert
the home or business.
Installation
Items needed:
Standard screwdriver
·
· 11/32" wrench

Step #1 – Attach Temp˚ Alert
After you have determined a location for the device to be mounted, position the attached template in the mounting location and mark the mounting holes with a
pen or other marking device. Depending on the type of surface you are mounting to, you may need to pre­drill holes to accept the mounting screws alone, or the
plastic anchors and mounting screws. Drive the screws into the mounting surface, allowing approximately 3/16" between the screw head and the mounting
surface. Engage the key slots on the back of the Temp˚ Alert
Step #2 – Making the Wiring Connections
Attach the connecting cable to any two open zones on any alarm panel, telephone dialer, wireless transmitter, etc. See Figure 1 for an example of the proper
wiring sequence utilizing an alarm system.
If desired, the green and black wires on the connection cable may be connected together under a single zone. This is useful whenever a limited number of open
zones are available and you do not wish to differentiate between a high and low temperature notification.
Step #3 – Selecting the High and Low Set Points
Each limit arm is controlled by an adjustment screw. To set a limit arm, slightly loosen the appropriate locknut (turn counter clockwise) with a 11/32" wrench
(See Figure 2). Next, use a screwdriver to set the limit arm to the desired temperature limit (See Figure 3). Once the arm is in the proper setting locations,
simply retighten the lock nut (turn clockwise) (See Figure 4). Avoid over tightening of the locknut. Repeat this process until both temperature limits have been
set. Make sure to retighten the locknut when temp limits have been set. The Temp˚ Alert
