NOTE!
In the event of a temperature sensor malfunction, the "Collective failure" light on the TSS or TS
panel and the MAC-FC controller issues a fault signal to the CSP. If a sensor malfunction is
detected, inform the SMAY service immediately. Do not repair or replace the sensor yourself.
This can only be done by SMAY service or an authorised SMAY service.

MAC-D-Min controller (2 and 4)
The MAC-D-Min is a digital pressure controller, designed to control 1 to 2 (2) and 3 to 4 (4)
damper actuators. It is equipped with an internal pressure sensor and connectors for power and
transmission via two Local FireBUS® channels. The built
-in internal microprocessor system
performs linearity corrections taking into account, among other things, the operating temperature
and the characteristics introduced during calibration. The high accuracy and stability of the
measurement is ensured by the use of high-end calibration devices and a long ageing process of
the device components.
The MAC-D-Min controller should be connected to the PZ box with a specified wire (or wires) of
maximum 20 m length.
