Wiring the outputs
Access plates
Figure 27 shows two access plates on top of the ACM 150 monitor. They are
provided for wiring the outputs. Remove one or both plates and cut or drill, as
necessary to accommodate your preferred connection, such as:

Relay output wiring
All 86 relays on the Relay Output Board have plug-in connectors. Remove the
connectors and wire to them outside of the monitor. Then, plug them into the board.
The connectors have 6 terminals accommodating 18 AWG or smaller wire. The relays
are numbered on the board, which is shown in
Standard output relays
There are 80 programmable relays. They have a default setup providing 40 Alarm
1 level and 40 Alarm 2 level outputs for up to 40 sample areas. Each relay is
independently programmable. The user can change configure set points, sample
areas and gases in any combination or grouping.
Six status relays are on the Relay Output Board. They activate when service request
or malfunction incidents are detected by the ACM 150 monitor or when power is lost.
It is highly recommended that these relays be connected to a continuously
monitored alarm system. These relays provide a verification of alarm conditions and
operational status that is separate from all other alarm outputs. They can provide
important information, if other communications links fail.
