Johnson Johnson MMX-8PJ Input Module

I. Overview:

The American Johnson MMX-8PJ detector interface module MMX-8PJ is a non-addressable device module. Intelligent detectors occupy a unique address on the bus and cannot be paralleled with conventional detectors. For large areas such as corridors, halls, and basements that require parallel installation, the interface module MMX-8PJ can achieve this. The interface module MMX-8PJ occupies one address in the loop bus. One MMX-8PJ can connect to 25 conventional detectors (considering the GBJ116-88 specification, it is recommended to have around 10 detectors in parallel).

II. Features:

l Supports compatible two-wire detectors.

l Monitors the status of input lines and external power supplies.

l Strong interference resistance (EMI/RFI).

l SEMS screws with washers for easy wiring.

l Electronic encoder setting.

l Built-in magnetic detection switch.

l LED flashes during regular operation and stays on during an alarm.

III. Parameters:

l Operating voltage: 22.2～25.5 VDC

l Quiescent current: 200uA (LED flashing)

l Current: 5.1mA (LED on)

l Terminal resistance: 3.9K ohms

l External power supply: 16～28VDC, ripple 0.1Vrms, 90 mA ( )

l Temperature range: -10℃～60℃

l Humidity range: 10%～95% non-condensing

l Dimensions: 114.3mm (height) x 101.6mm (width) x 31.75mm (thickness)
