TECHNICAL FEATURES
Microprocessored Module compatible with Notifier protocol, MMT is designed to manage a single detector. For correct
module working it is necessary 24Vdc regulated source power (it is possible to feed module from panel or from an external
power supply). The module is also provided of power output for gas detector on block connector. The internal power supply
is optoisolated from communication line.
ELECTICAL FEATURES
LED output: suited for INDICATOR.
4÷20mA input: PTC protected input voltage of
30 Vdc, impedance input 155ohm to ground.
Loop voltage input: 15÷32 Vcc.
Stand-by loop:
24Vdc, answer each 5 sec. and LED on: 350μA Typical
growth (resp. 0,2Hz) LED on 70μA
Typical growth (resp. 0,2Hz) without protection 30μA.
External power input: 15÷30Vdc max (optoisolated from
loop).
Current fromm external power supply: 10mA max
(module) + current necessary to feed GAS detector
Gas detector power output: prtected by 400mA
automatic fuse protection
Maximum current output: 300mA.
NOTE 1 - In supervision mode the module checks the power supply voltage beetwen 3 – 4 terminals.
When the tension is lower then 4 Volt the module reports a falut signal to the control panel.
ADDRESS CONFIGURATION
Each module use one of 99 available address for detectors
on loop. The module addressing is achieved through decimal
rotative switches (1-99)
