1. The CX-12 mounts on a 4" square (or 4x4) electrical box supplied by the contractor. Do not mount the CX-12
inside another box, unless it has good air flow through it.
2. There are two terminals for the mains power connection labeled L (line) and N (neutral). Mains connections
should be done in accordance with National and Local Electrical Codes. Only qualified personnel should
connect mains power to any device.
3. There are two terminals for the dry alarm relay contacts with no polarity preference. The alarm relay can
switch up to 0.5 A 120 V, or 60 VA. The alarm relay is activated if gas reaches or exceeds the alarm settings.
See section 4.5 Configuration "CON" for details on relay settings.
4. The alarm relay can be configured to normally open (default) (N.O.) or normally closed (N.C.) and will
activate:
a. if either the CO or NO
concentration drops below the alarm set point. Note that setting both "ArS.C" and "ArS.n" to "diS"
will cause the alarm relay not to engage.
b. during a power up test "PUt".
c. when a trouble condition is present.
5. The dry contact, SPDT fan relay has three terminals. The common (COM.), normally open (N.O.) and the
normally closed (N.C.) contact. The fan relay can switch up to 5.0 A up to 240 VAC. See section 4.5
