Fig. 15.14 Diagram of connecting the line with fault monitoring to the P-MACF pressure sensor.
Depending on the functions of the converters, we distinguish between several types:
- P-MACF +/-250 - measurement range: -250;250Pa - measurement in a protected space
- P-MACF +/-600 - measurement range: -600;600Pa - measurement in a protected space or
measurement of the compression ratio in a duct
NOTE!
In the event of a pressure sensor malfunction, the "Collective fault" 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.

T-MACF temperature sensor
T-MACF is a digital temperature transmitter equipped with one temperature sensor and
connectors for power supply and transmission via two Local FireBUS channels. The built-in
internal microprocessor system performs linearity corrections taking into account the
characteristics in time. 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 T-MACF sensor is used in SAFETY WAY reversible systems to measure the temperature
difference between the outside temperature and the staircase temperature in order for the system
controller to determine the direction of air flow in the secured staircase. As standard, eight
temperature sensors are recommended for a single staircase, of which 4 measure the outside
temperature and 4 measure the inside temperature of the staircase.
The maximum number of T-MACF temperature sensors mounted on one Local FireBUS loop is 8.
24VDC power supply.
On request IP65 protection class can be delivered.
