Introduction
Primex Wireless’s Synchronous Network System (SNS™) digital clock/timers are equipped with both a
wireless 802.11 b/g interface and a wired Ethernet port interface. Viewable up to 150 feet away, these
bright LED-digit clock/timers are perfect for hallways and large rooms. They’re also easy to install –
simply connect the power source and the clock/timer is instantly synchronized to the Primex Wireless
system.
Primex Wireless digital clock/timers can be installed anywhere indoors within range of an 802.11 b/g
access point. The clock/timers are able to connect in an existing wireless LAN (WLAN), supporting a
wide variety of security protocols.
The initial setup procedure for all SNS digital clock/timers can be done by Primex Wireless prior to
shipping or can be done with the Configuration Tool software at your facility in a convenient central
location such as a maintenance area or at the final location of the clock/timer. For detailed instructions
on the use of the Configuration Tool software, please see the Primex Wireless Configuration Tool
Software User Guide. Once the digital clock/timers are configured using the Configuration Tool
software, settings can be altered using Primex’s Applications Management Platform (AMP™). AMP
has features to determine the signal strength of the digital clock’s reception.
The digital clock/timers connect to the WLAN only at the times configured with AMP or the
Configuration Tool software. Any changes in configuration of a digital clock/timer via AMP will be
transmitted to the digital clock/timer the next time the digital clock/timer connects to the WLAN. For
detailed instructions on the use of AMP, please see the Primex Wireless Applications Management
Platform (AMP™) User Guide.

SNS digital clock/timer installation
These clock/timers require either a standard CAT-5 network cable with an RJ-45 connector or access
to an 802.11 b/g wireless local area network (WLAN).
Primex Wireless SNS digital clock/timers and timers are
shipped from the factory with either a three-prong grounded
plug or pigtail for permanent installation. Pigtail installations
require a 120V~ power line in a 4” x 4” junction box installed
by a licensed electrician.
Note: Please be sure to leave a minimum of 6” of pigtail
inside the junction box.
Any damage to the clock or timer due to improper wiring
voids the warranty.
There are three ways to mount an SNS digital clock/timer:
• Tilt-bracket clock/timer installation
• Direct wall-mount clock/timer installation
• Flush-mount clock/timer installation
In addition, SNS elapsed timers and Code Blue timers include a control switch that must be mounted in
a separate location.
• Timer control switch installation

Tilt-bracket clock/timer installation
Hard-wired installations require a 120V~ power
line in a 4” x 4” junction box installed by a
licensed electrician. The tilt bracket has a center
pass-through hole for the 120V~ pigtail.
Note: The RJ-45 jack for the network cable is
on the bottom of the clock/timer. Most
building codes prohibit running network
cables through the same junction box as
line voltage.
You may mount the tilt bracket directly to the wall
with four #10 screws and anchors (provided).
See dimension G and H in the SNS digital
clock/timer dimensions
table for the spacing of
the screws. If a junction box is present, the tilt
bracket also has mounting holes spaced to allow
direct attachment of the tilt bracket to the coverplate screw holes on the junction box.

Step 1
Step 3
Step 7
1. Prepare an opening using the following dimensions: 5.5”H x 14.25”W.
2. Inside the opening install an expandable fan brace bar between the wall studs. The brace bar
should be a couple of inches below the opening, so that when the electrical box is attached with a
“U” clamp to the brace bar, it will still be below the opening in the wall.
Note: UL Listed 59E expandable brace (or equivalent) recommended.
3. Prepare 0.125" - 0.1875" diameter screw holes, spaced 16” wide and 5.25” high as in the picture
above. Predrilling holes for screws is optional, as screws are self-driving in certain materials. Wall
anchors are provided for installations that require anchoring.

4. Connect the wires to the electrical box with the appropriate fittings. Then use a “U” clamp to attach
the electrical box to the brace bar.
Note: Leave enough extra wire length (armored cable) so that the electrical box can be wired in the
5.5”H x 14.25”W opening.
5. Connect the appropriate fitting to the clock/timer cord and then attach the fitting to the electrical box.
Then connect the wires in the electrical box as follows:
Note: The clock/timer should be supported during this assembly.
A. Green or green/yellow is connected to ground
B. White or blue is connected to neutral
C. Black or brown is connected to line (Hot lead)
6. Cover the electrical box
Caution: Due to the permanent nature of this installation, all settings on the clock/timer must be
correct before continuing. The clock/timer's ability to receive a signal must also be verified.
7. Remove adhesive backing and assemble faceplate onto the clock/timer.
8. Secure the clock/timer to the wall using the included screws. #10-16 x 1.25” (Qty 4).
9. Remove protective film from the lens after installation.
10. Apply silicone sealant (provided) around all edges of the clock/timer. Refer to the sealant
instructions for application details.

Timer control switch installation
SNS elapsed timers and Code Blue timers include a control switch that must be mounted in a singlegang junction box (not included). These boxes are typically 2¼” x 2¾” x 4” (5.72cm x 6.99cm x
10.16cm).
The switch’s wall plate cover is stainless steel. The switch’s buttons and wall plate cover may be
cleaned with water and/or most common disinfectant.
Note: Be sure to test any cleaning solutions on a small area of the switch before using it on the entire
switch.
The switch is not connected to the clock/timer for shipping. Because of this, the cable, which is
attached to the back of the clock/timer, needs to be connected to the switch. The cable is a 15-ft (4.6m)
standard telephone cable with an RJ-11 connector for connection to the switch. It can be extended up
to 100 feet (30.48m).
