System Sensor 2100S and 2100TS Photoelectronic - Manual (Page 2)

D200-54-00 2 I56-710-14R
The detectors also include an output that allows an option-
al Model RA400Z Remote Annunciator to be connected.
Mounting
Each 2100S and 2100TS detector is supplied with a mount-
ing bracket that permits the detector to be mounted:
1. To a single gang box, or
2. Directly to a 31/2-inch or 4-inch octagonal box, or
3. To a 4 inch square electrical box by using a plaster ring.
4. Directly to the ceiling using drywall anchors, if permit-
ted by local codes and/or the authority having jurisdic-
tion.
Tamper-resistance Feature
This detector includes a tamper-resistant feature that pre-
vents its removal from the bracket without the use of a tool.
To make the detector tamper-resistant, remove the smaller
tab by breaking it at the scribed line on the tamper-resist-
ant tab on the detector mounting bracket (see Figure 2),
then install the detector. To remove the detector from the
bracket once it has been made tamper resistant, use a
small screwdriver to depress the tamper-resistant tab, locat-
ed in the slot on the mounting bracket, and turn the detec-
tor counterclockwise.
Wiring Installation Guidelines
All wiring must be installed in compliance with the
National Electrical Code, applicable local codes, and any
special requirements of the local authority having jurisdic-
tion. Proper wire gauges should be used. The conductors

accessory devices should be color-coded to reduce the like-
lihood of wiring errors. Improper connections can prevent
a system from responding properly in the event of a fire.
The screw terminal block will accept 14 – 22 gauge wire.
For best system performance, all wiring should be installed
in separate grounded conduit; do not mix fire system
wiring in the same conduit as any other electrical wiring.
Twisted pair may be used to provide additional protection
against extraneous electrical interference.
Wire connections are made by stripping about 1/4 inch of
insulation from the end of the feed wire, inserting the wire
into the appropriate terminal, and tightening the screw to
secure the wire in place.
System Sensor smoke detectors are marked with a compat-
ibility identifier located as the last digit of a five digit code
stamped on the back of the product. Connect detectors only
to compatible control units as indicated in System Sensor’s
compatibility chart which contains a current list of UL list-
ed compatible control units and detectors. A copy of this
list is available from System Sensor upon request.
Installation
Remove power from the control unit or initiating-device
circuits before installing detectors.
1. Wire the plug-in screw terminal block per Figure 3 and
plug the terminal block into the detector.
2. Align the arrows on the detector with the arrows on the
mounting bracket.
3. Turn the detector clockwise in the mounting bracket
until it clicks into place.
4. After all detectors have been installed, apply power to
the control unit or initiating-device circuits.
5. Test the detector as described in TESTING. (See page 3.)
6. Reset the detector at the system control panel.
7. Notify the proper authorities the system is in operation.
