Apollo manufactures a comprehensive range of interfaces for systems which enable fire protection solutions to
be engineered simply and e”ectively without the need for custom-designed equipment. These interfaces are available for use on Apollo addressable systems.

Apollo XP95 Input / Output Unit with Isolator

Product code: 55000-847APO

The Input / Output Unit provides a voltage-free, double pole changeover (DPCO) relay output, a single monitored switch input and an unmonitored, non-polarised input.

Product code: 55000-852APO

The Sounder Control Unit is used to control the operation of a zone of conventional sounders and report their status to the control panel.

The sounder control unit with isolator allows the device to be operated continuously or be pulsed with 1 second on and 1 second off. The Devices can be operated individually or in groups and whichever address mode has been applied, may be synchronised when in pulsed operation.

Product code:55000-845APO

The Zone Monitor powers and controls the operation of a zone of up to 20 Apollo Series 65 or Orbis Fire Detectors from a Discovery or XP95 loop. The Zone Monitor with Isolator is loop powered and operates at 17–28V DC with protocol pulses of 5–9V.

Product code:55000-849APO

The Output Unit provides a voltage free single pole, changeover relay output. It is a simplified version of the Input/Output Unit without circuitry for monitoring inputs.
