NOTE: ABOVE DIAGRAM SHOWS NFPA REQUIRED WIRING OF SUPERVISED
SYSTEMS. SCHEMATIC SHOWN BELOW FOR REFERENCE.

Locate installations where normal ambient temperatures do
not exceed 100°F.
Wiring Instructions
NOTE:
Refer to the manufacturer’s instructions for releas-
ing device wiring.
NOTE:
To ensure that electrical connections are super-
vised, do NOT loop wires under terminals 8, 9, 10,
and 11. Cut the wire at each terminal.
To make electrical connections, strip approximately
3
⁄
8
"
(1 cm) insulation from the end of each wire, slide the bare
wire end under the clamping plate, and tighten the clamp-
ing plate screw. Use the strip gauges molded into the inside
and underside of the base for ease of wiring to terminals 1
and 4, and to terminals 6 through 14, respectively.
The zone wiring of the detector base should be checked
before installing the smoke detector heads. The base con-
tains a built-in shorting spring to make this possible. After
the detector base is wired and mounted to an electrical box,
position the shorting spring against terminal 3. This tem-
porary connection energizes the supervisory relay and per-
mits the wiring of the loop to checked for continuity.
After all detector bases have been mounted, wired, and the
wiring checked, install the detector heads. The shorting
spring in the base automatically disengages when the
detector head is removed from the base. DO NOT remove
the shorting spring since it reengages as the detector head
is turned into the base, completing the circuit.
Tamper-resistance Feature
This detector base can be made tamper resistant so it can-
not be removed without the use of a tool. To make the base
tamper resistant, simply break off the tab on the base (see
Figure 4A), before installing the detector.
