APPENDIX A - SPECIFICATIONS

This section of the handbook provides specification information about the following components:
• Transmitter Unit
• Certified Sensor
• Cartridges
• Accessories
• LonWorks Communication Board
A.1 TRAnSmiTTER UniT And SEnSOR
The Apex Transmitter Unit is designed to operate with the Certified Sensors specified in the tables
later in this section. The Certified Sensors are designed so that they all have a common electrical
interface to the Transmitters Unit. The cartridge data is digitised and processed into a gas reading
by the Certified Sensor. The decision on whether gas alarms are present is also made within the
Certified Sensor.
A.1.1 Gases and Ranges
The Transmitter Unit with Certified Sensor can be fitted with any of the cartridges listed in the tables
in section A.2.
A.1.2 Input/Output
Power supply:
Power consumption:
Relays:
+24VDC nominal (18-32V). Total power supply loop resistance should
be less than 30 ohms with ECC cartridge, 16 ohms with Catalytic
cartridge.
Relays active - 3.6W ECC cartridge, 5.6W Catalytic cartridge.
Three relays: A1, A2 and Fault.
Contact rating: 100mA (min), 2A (max) at 30Vdc non-inductive except
UL/CSA where specification is +28VDC 1A.
Single pole change-over type connected to two terminals:
• one terminal connected to the relay common
• one terminal connected via a user configurable link to either the
relay contact normally open or normally closed.
Relays are user configurable to be normally energised or normally
de-energised.
Relays are user configurable to be latching or non-latching. Latched
relays can be reset by the keypad, by the digital communications link
(optional) or by the removal of power.
