It can report fault, switch open and switch closed levels

The Mini Switch Monitor is loop powered and operates at 17-28V DC with protocol pulses of 5-9V.
The Mini Switch Monitor is a miniature interface. The monitor is designed to fit into equipment with limited space or to be mounted within an enclosure such as a manual call point. The monitor can also be fitted onto a standard 35mm DIN-rail using a twist-click motion. The Mini Switch Monitor is designed to monitor the state of one or more single-pole, volt-free contacts. It also reports the contact status to Apollo compatible fire control panels. The Mini Switch Monitor features a 20I short-circuit isolator as standard and can be used as an interrupt or non-interrupt device. The interrupt feature (selected via the DIL Switch) means the monitor can be used where a priority response is required, in particular for monitoring an individual or a zone of conventional manual call points.
Note: When the eighth section of the DIL switch is changed, the Mini Switch Monitor will change the type code it sends to the panel. The panel will have to be programmed to accept this change. The unit provides "normal", "fault", "pre-alarm" and "alarm" states to the control equipment. For the states are derived from the switched resistive values refer to the Datasheet (PP2282). The device accepts a maximum line resistance of 50? and requires a 20k? End-of-Line resistor.
The Mini Switch Monitor is moulded from the same white self-extinguishing polycarbonate as Apollo detectors.
The unit has three status LEDs, one red, one green and one yellow.
The red LED is switched by the control panel and illuminates in the event of an alarm condition being detected.
The green LED means that the device is polled.
The yellow LED can either mean a short-circuit on loop-wiring (constant) or a fault on the monitored circuit (pulsing).
The unit has provision for a remote LED which is switched by the control panel.
The length of cable used for the remote LED must not exceed 3m.

The Mini Switch Monitor is an interface within an entirely new housing. This allows the unit to be fitted onto a standard 35mm DIN-Rail (using a twist-click motion) or mounted within an enclosure, for example a manual call point.
It is designed to monitor the state of one or more single pole, volt-free contacts connected on a single pair of cables and to report the status to Apollo compatible analogue addressable control equipment.
