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.
- 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.
