BEFORE INSTALLING
Please read the System Smoke Detector Applications Guide, which provides
detailed information on detector spacing, placement, zoning, wiring, and spe-
cial applications. This manual is available online at www.systemsensor.com.
NFPA 72 guidelines should be observed.
NOTICE: This manual should be left with the owner/user of this equipment.
IMPORTANT: The detector used with this base must be tested and maintained
regularly following NFPA 72 requirements. The detector should be cleaned at
least once a year.

MOUNTING
Mount the mounting plate directly to an electrical box. The plate will mount
directly to 4-inch square, 4-inch octagon, 3 ½-inch octagon, single gang and
double gang junction boxes.
1. Connect field wiring to terminals, as shown in Figure 3.
2. Attach the mounting plate to the junction box as shown in Figure 2.
3. To mount the base, hook the tab on the base to the groove on the
mounting plate.
4. Then, swing the base into position to engage the pins on the product
with the terminals on the mounting plate.
5. Secure the base by tightening the mounting screws.
6. Install a compatible smoke detector as described in the installation
manual for the detector.
INSTALLATION AND WIRING GUIDELINES
All wiring must be installed in compliance with all applicable local codes
and any special requirements of the local authority having jurisdiction. Proper
wire gauges should be used. 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 connections can prevent a system from
responding properly in the event of a fire.
For signal wiring (the wiring between interconnected detectors), it is recom-
mended that the wire be no smaller than 18 AWG (0.823 square mm). Wire
sizes up to 12 AWG (3.31 square mm) may be used with the base. The base
will be shipped with the screw terminals set for 14 AWG wiring. If 12 AWG
wire is used, back out the screws to allow the wire to fit beneath the clamp-
ing plates.
Make electrical connections by stripping about 3/8 inch (10 mm) of insulation
from the end of the wire (use strip gauge molded in base). Then slide the wire
under the clamping plate and tighten the clamping plate screw. Do not loop
the wire under the clamping plate. (See Figure 4)
Wire the normally open (NO) line to terminal 3 (see Figure 3). Insert the nor-
mally closed (NC) line of the relay to terminal 1 and the relay common line
to terminal 2. Wire the communication lines in (–) and out (–)to terminal 4.
Insert the communication line in (+) and out (+) to terminal 5.
Check the zone wiring of all bases in the system before installing the detec-
tors. This includes checking the wiring for continuity, correct polarity, ground
fault testing and performing a dielectric test.
The base includes an area for recording the zone, address, and type of detec-
tor being installed. This information is useful for setting the detector head
address and for verification of the detector 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.
Alarm system control panels have specifications for allowable loop resistance.
Consult the control panel specifications for the total loop resistance allowed
before wiring the detector loops.
WARNING
The base uses a latching relay that can change states if it is subjected to me-
chanical shocks or jarring. As a result, even though relay contacts are in the
open state when the base is shipped from the factory, the contacts may have
closed during shipment.
Connecting an auxiliary control circuit to closed relay contacts can cause an
unexpected, and possibly dangerous, activation of that circuit. Therefore, do
NOT connect an auxiliary control circuit to the relay contacts (terminals 1, 2,
and 3) before ensuring that the relay contacts are in their open state. Ensure
that the contacts are open by applying power to the bases WITHOUT the de-
tector heads installed.

TAMPER-RESIST FEATURE
NOTE: Do not use the tamper-resist feature if the removal tool will be used.
The detector base includes a tamper-resist feature that prevents removal of
the detector from the base without using a small screwdriver or similar tool.
To activate this feature, use needle-nose pliers to break the tab on the detector
base as shown in Figure 5A. 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 from the top and
press down on the lever (see Figure 5B). This allows the detector to be rotated
counterclockwise for removal.
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.
