System Sensor B501B-FTX User manual

D200-74-00 1 I56-1195-01R
Before Installing
Please thoroughly read the system wiring and installation
manuals, and manual I56-407, Guide for Proper Use of
System Smoke Detectors, which provides detailed informa-
tion on detector spacing, placement, zoning, and special
applications. Copies of these manuals are available at no
charge from System Sensor.
NOTICE: This manual should be left with the owner/user
of this equipment.
IMPORTANT: The detector used with these bases must
be tested and maintained regularly following NFPA 72
requirements. The detectors should be cleaned at least
once a year.
Mounting
The detector base mounts directly to 31⁄2- and 4-inch octa-
gon and 4-inch square boxes, with or without a plaster
ring.
To mount, remove the decorative ring by rotating it in either
direction to unhook the snaps. Then, separate the ring from
the base. Install the base on the box, using the screws sup-
plied with the junction box and the appropriate slots in the
base. Replace the decorative ring on the base and rotate it in
either direction until the ring snaps in place (see Figure 1).

Installation Guidelines
All wiring must be installed in compliance with all appli-
cable local codes and any special requirements of the local
authority having jurisdiction, using the proper wire sizes.
The conductors used to connect smoke detectors to control
panels and accessory devices should be color-coded to
reduce the likelihood of wiring errors. Improper connec-
tions can prevent a system from responding properly in the
event of a fire.
For signal wiring (the wiring between interconnected detec-
tors), it is recommended that the wire be no smaller than
18 gauge (1.0 square mm). However, wire sizes up to 12
gauge (3.3 square mm) can be used with the base. The
use of twisted pair wiring or shielded cable for the power
(+ and –) loop is recommended to minimize the effects of
electrical interference.
If shielded cable is used, the shield connection to and from
the detector must be continuous by using wire nuts, crimp-
ing, or soldering, as appropriate, for a reliable connection.
Alarm system control panels have specifications for allow-
able loop resistance. Consult the control panel specifica-
tions for the total loop resistance allowed before wiring
the detector loops.

Three-Year Limited Warranty
System Sensor warrants its enclosed smoke detector base to be free from
defects in materials and workmanship under normal use and service for a
period of three years from date of manufacture. System Sensor makes no
other express warranty for this smoke detector base. No agent, represen-
tative, dealer, or employee of the Company has the authority to increase
or alter the obligations or limitations of this Warranty. The Company’s
obligation of this Warranty shall be limited to the repair or replacement
of any part of the smoke detector base which is found to be defective in
materials or workmanship under normal use and service during the three
year period commencing with the date of manufacture. After phoning
System Sensor’s toll free number 800-SENSOR2 (736-7672) for a Return
Authorization number, send defective units postage prepaid to: System
Sensor, Repair Department, RA #__________, 3825 Ohio Avenue, St.
Charles, IL 60174. Please include a note describing the malfunction and
suspected cause of failure. The Company shall not be obligated to repair
or replace units which are found to be defective because of damage,
unreasonable use, modifications, or alterations occurring after the date
of manufacture. In no case shall the Company be liable for any conse-
quential or incidental damages for breach of this or any other Warranty,
expressed or implied whatsoever, even if the loss or damage is caused by
the Company’s negligence or fault. Some states do not allow the exclu-
sion or limitation of incidental or consequential damages, so the above
limitation or exclusion may not apply to you. This Warranty gives you
specific legal rights, and you may also have other rights which vary from
state to state.

Wiring Instructions
Make wiring connections by stripping about 3⁄8″(10 mm)
of insulation from the end of the wire. Then, slide the wire
under the clamping plate and tighten the clamping plate
screw.
Wire the remote annunciator (RA) line to terminal 3 (see
Figure 2). Wire the communication lines in (+) and out
(+)to terminal 1. Insert the communication line in (–) and
out (–) to terminal 2. Terminal 4 is for shielded cable only
(see Figure 2). If shielded cable is used, the shield connec-
tion to and from the detector must be continuous by using
wire nuts, crimping, or soldering to ensure a reliable con-
nection. If shielded cable is not used, leave terminal 4 in the
screwed-down position.
Wire the auxiliary power supply positive line to the
AUX(+). Wire the auxiliary power supply return to the
AUX(–).
Insert the 5-wire connector on the mounting base into the
5-pin connector located on bottom of the Filtrex unit.
Check the zone wiring of all bases in the system before
installing detector heads. This includes checking the wir-
ing for continuity, correct polarity, ground fault testing, and
performing a dielectric test.
A label is affixed to the base for recording the zone,
address, and type of detector being installed at the base
location. This information is useful for setting the detec-
tor head address and for verification of the sensor type
required for that location.
Once all detector bases have been wired and mounted, and
the loop wiring has been checked, the detector heads may
be installed in the bases.
Tamper-resist Feature
This detector base includes a tamper-resist feature that pre-
vents its removal from the base without the use of a tool.
To activate this feature, break the tab from the detector
base as shown in Figure 3A. Then, install the detector.
To remove the detector from the base once the tamper-
resist feature has been activated, insert a small-bladed
screwdriver into the slot in the side of the base and push
the plastic lever away from the detector head (see Figure
3B). This allows the detector to be rotated counterclockwise
for removal.

NOTE: Head removal after the tamper-resist feature has
been activated first requires removal of the decora-
tive ring.
The tamper-resist feature can be defeated by breaking and
removing the plastic lever from the base. However, this
prevents the feature from being used again.
