INSTALLATION
Distribute the manual station boxes throughout the protected area so that they
are unobstructed, readily accessible, and located in the normal exit path. Place the
manual station according to the regulations of the authorities having jurisdiction.
Surface Mounting
Mount the backplate to a Model SB-5R Backbox as shown in Figure 4.
Flush Mounting
Mount the backplate to a user supplied single gang switchbox.
Do not overtighten the screws. Overtightening may distort the backplate.

NOTES
:
1. Recommended wire sizes:
18 AWG minimum, 14 AWG maximum
2. Wire larger than 14 AWG can damage the connector.
3.
When using shielded cable without metal raceway or with
nonmetallic raceway,
the shields should be terminated at the device
ground terminal. If the device box is already grounded by another
means, such as being mounted to a grounded structure, the wire
shields should be continuous and must be grounded solely at the point
of origin; for example, at the control panel.
4.
When using shielded cable with metal raceway,
the wiring shields
shall be continuous and grounded solely at the point of origin. The
device ground terminal shall be connected to the grounded device box.
5.
When using metal raceway without shielded cable,
connect the
device ground terminal to the grounded device box.
6. Metal raceway should be thoroughly grounded throughout the system.
7. In supervisory: All HMS manual stations draw 1mA.
8. All HMS manual stations are polarity insensitive devices. Line 1 and
Line 2 can be either line of the DLC or FS-DLC loop.
