System Sensor M500MB Monitor/Module

The System Sensor M500MB Monitor provides a two-wire, or fault-tolerant, initiating circuit for normally open contact fire alarm and supervisory devices, or either normally open or closed security devices. M500M Control Modules allow a compatible control panel to switch discrete contacts by code command.

The control module has a status LED that can be a latch on or return to the normal mode by code command from the panel. Accordingly, rotary decade switches are used to set the address of each module. In addition, the control module offers two modes of switching operation. When his ship, the module is configure to switch an external power source. The external power source can be a DC power supply or an audio amplifier. In this mode, the module reports the supervision status of the connected loads to the control panel.

In addition, they load circuit status is a report as a NORMAL, OPEN, or SHORTED circuit. Two pairs of output termination points are available for fault-tolerant wiring. The second mode of switching operation allows the panel to control one Form-C (SPDT) set of contacts. Circuit connections to the contacts are not direct by the module.

Also, the System Sensor M500MB Monitor provides the interface to contact devices, such as security contacts, water flow switches, or pull stations. They also are capable to supervise wiring to the load device. they have conventional 4-wire  that will be check through their alarm and trouble contacts.
