Product Details:
Honeywell MS8120F1200 damper actuator is designed for operating fire & smoke dampers in ventilation and air conditioning systems. This fast-acting actuator can close the damper within 15 seconds, in the event of a fire.
Features:
It has a unique, patent-pending design to eliminate the need for limit switches to reduce power consumption.
It offers reversible mounting configuration to allow use in either clockwise (CW) or counter-clockwise (CCW) spring rotation.
The integral spring return delivers a maximum return torque of 175 inch-lb at a temperature of 350 degrees F.
It comes with die-cast aluminium housing to allow flush mounting to the damper and includes a high-temperature indicator to indicate device heating.
Standards and Approvals:
CE
cULus
UL873
NEMA 1
Frequently Asked Questions:
Q. How to install a damper actuator?
A.
Place the actuator over the damper shaft and hold the mounting bracket in place.
Mark screw holes on the damper housing.
Remove the actuator and mounting bracket.
Drill or centre-punch holes for mounting screws.
Turn damper blades to normal (closed) position.
Place the actuator and the mounting bracket back into position and screw the bracket to the damper box with steel metal screws.
Tighten set screws securely using a 1/4 inch wrench.
Q. What is the purpose of a junction box?
A. The damper actuator includes a junction box that encases electrical connections. The junction box protects the electrical connections from external factors and reduces the chances of accidental electrical shocks.
Q. What is the use of a self-centring shaft adapter?
A. A self-centring shaft adapter (shaft coupling) allows accommodating a wide range of shaft sizes for secure connections.
