Aspirating Smoke Detection System Accessories

Senator Command Module
Provides a single location display, control and interfacing option for systems of up to 127 detectors. The Command module allows global programming of all detector functions simultaneously.Large LCD and LED status indications. Requires external 24vdc supply.Dimensions: 425w x 370h x 115d

Senator 19" rack command module
Command module as per part no. 30624. Constructed in a compact stainless steel enclosure enabling mounting in a 3U high 19" rack mount cabinet.

Senator Command Module - steel enclosure
As per part number 30624-KID with a steel front cover for industrial type applications. Requires external 24vdc supply.Maximum pipe length: 4 x 50mDimensions: 425w x 370h x 115d

Senator Remote Display Unit (RDU)
The RDU connects to the Senator range of detectors using the RS485 data bus and mimics the LED status indications of the detector. The RDU monitors the status of a single detector. More than one RDU can be allocated to a single detector. The RDU can be mounted in either a single wall mounted enclosure or a 3U high 19" rack enclosure. Requires a 24vdc supply.

RDU Relay board
This is an optional relay board which can be used with the Senator RDU to provide Volt Free Changeover Contacts for signalling to other equipment. Five relays are provided for Fire 1, Fire 2, Pre-alarm, Aux Alarm and Fault (energised).

APIC card - Apollo protocol
Can be fitted internally to any Senator detector unit or Command Module allowing them to be connected to an Apollo protocol addressable loop. A single APIC may be used in Multi Address mode when installed inside a command module for signalling up to 127 detectors onto the addressable loop reducing costs on larger systems.

Nano communication card
Optional card for installation in the Senator Nano Aspirating Detector. The communications card allows the Senator Nano to be connected to a PC or SenseNET network.

Relay/Input card
The Relay/Input card can be fitted into the Senator 25 and 100 detectors to provide an additional five relay outputs for signalling to other equipment. Three inputs are provided on the card that can be programmed for remote reset, isolate, classifire override or PSU fault monitoring.
