NORMALLY CLOSED PROGRAMMABLE SWITCHES
(SEE NOTES 1, 3, 4, AND 5)
The terminals
TB-EOL
NOTES:
1.
Mount EOL on the TB-EOL terminal.
2.
The EOL resistor must be mounted at the last switch (normally open switch).
3.
TB-EOL will not come with the package of product. Use Siemens TB-EOL, P/N S54322-F4-A2, or equivalent.
4.
EOL 470 ohms, 1% 1/2W will come with the package of product.
5.
For multi-normally closed switches monitoring, the open fault between switch will not be supervised.

WIRING
(Refer to Figures 6 and 13) Refer to the appropriate wiring diagram below and wire the addressable
interface module accordingly.
NOTE:
Recommended wire size:
18 AWG minimum
14 AWG maximum
Wire larger than 14 AWG can damage the connector.
POWER LIMITED WIRING
In compliance with NEC Article 760, all power limited fire protective signaling conductors must be
separated a minimum of ¼ inch from all of the following items located within an outlet box:
•
Electric light
•
Power
•
Class 1 or non-power limited fire protective signaling conductors
To meet the above requirements, the following guidelines must be observed when installing this
interface module.
NOTE: If power limited wiring is not used within this outlet box, then these guidelines do not apply. In
that case, be sure to follow standard wiring practices.
XTRI-R CONTROL MODULE
The XTRI-R Control Module Barrier must be used when the XTRI-R relay contacts are connected to
non-power limited lines. Break apart the barrier to the correct size and shape shown in Figure 6 for
either the 4-inch square or double gang box. Install the barrier diagonally into the backbox to create two
separate compartments within the backbox to separate the wires, as shown in Figure 6.
