Safety Regulations Read this manual carefully before using the SENTRY io. The SENTRY io will perform as designed only if it is used and maintained in accordance with the manufacturer's instructions. Otherwise, it could fail to perform as designed and persons who rely on the SENTRY io for their safety could sustain serious personal injury or death. -
Page 6: Correct Use
The SENTRY io is designed to accept standard 4-20 mA analog signal inputs from connected MSA or generic gas detectors and will also accept discrete inputs from contact closure devices such as switches or relay contacts. The system provides discrete relay outputs for use in energizing notification devices such as sounders, strobes, or horns. -

Page 10: Input Devices Compatibility
Analog Inputs The SENTRY io is designed to provide 24 VDC field device power for connected, 2 and 3-wire 4-20 mA signal fixed gas detectors. The wiring termination blocks for connected gas detectors are located in the lower left hand corner of the panel. -
Page 11: Output Devices Compatibility
The wiring termination blocks for discrete input device connections are located to the right of the 4-20 mA signal input terminal blocks and utilize a two-tier terminal block. The SENTRY io enables the internal 24 VDC power to be used for the discrete 24 VDC signal inputs. - Page 12 The SENTRY io comes pre-wired with all contacts dry except for relays 5-8 (which includes the buzzer on relay 5). To add additional powered relays, you need to connect 0 VDC and 24 VDC to the terminal strip as shown below. Powered contacts are used for things like horn and strobe activation.

SENTRY io enclosure before doing work inside the enclosure. ESD can cause damage to the SENTRY io. Do not touch the electronic circuit boards. When closing and latching the SENTRY io door, ensure the enclosure door seal is free from debris and the door is tightly sealed. -
Page 18: Electrical Installation Procedure
7. Connect the AC power wiring to the #1 AC terminal block (HOT) and #2 AC terminal block (NEUTRAL) input terminals. Make sure the connectors are seated securely. 8. Connect the AC power ground wire to the ground lug so the SENTRY io chassis ground is connected to the earth ground. - Page 19 When wiring each node, connect the cable shield to the functional ground point of the RS485 terminal block. In order to avoid ground-loops, do not connect the RS485 functional ground terminal to the Earth of the SENTRY io as it is internally connected to the SENTRY io's functional ground point.

Operation Dashboard NOTE: On some instruments, CLO2 and CO2 show as two decimal places (x.xx). The SENTRY io is limited to one decimal place (x.x). NOTE: Some Oxygen instruments have a calibration output signal >20mA and may display as "overrange" on the SENTRY io. - Page 33 Alarm 3 to 22. If synchronizing with the SENTRY io, it is best to set alarms to a 2 alarm configuration on the SIO since it will never show the alarm above 22.
