Communication To Controller; Relay Outputs - Honeywell 301EM Mode D'emploi

Communication to Controller

Terminal J10 is for communication connections from the 301EM to the
301C Controller. The cables must be grounded using the shield terminal.
The network can be up to 2000 ft. (609 m) per channel. The length of a T-
tap can be a maximum of 65 feet (20 m). A maximum of 130 ft. (40 m) for
all the T-taps must be respected.This diagram illustrates network
communication wiring on terminal J10; wires come in from a previous
device and go out to the next device.

Relay Outputs

The relay outputs will withstand up to 5 amps
at 30 Vdc or 250 Vac (resistive load only).
They can be used to activate horns, strobes,
etc. Refer to the drawing for proper wiring.
Failsafe Relay Outputs
When power is applied to the 301EM, these
relays are also powered up. The devices
connected to these outputs will be triggered
when power is cut, which allows detection of
power failures or interruptions.
The 301EM is factory configured in Normal
mode, which means that the relay outputs
are not in failsafe mode.
See the APPENDIX section for more details about B-52 and
ASHRAE 15 standard configurations.
