Four-Wire Circuit Installation
1. Use 18 AWG FPL cable such as Honeywell
AK4704ARE.
2. Secure the smoke alarm reset relay module in the
bottom of the Honeywell 7000 System metal box as
shown in Fig. 19 with double-sided tape (provided).
3. Install smoke and heat detectors in accordance with
manufacturer instructions.
4. Wire the circuit as shown in Fig. 16.
IMPORTANT
Do not exceed the +13.8V total current draw with all
detectors in alarm.
5. Connect the End-Of-Line Module at the last smoke
detector. All wire leads must be insulated with a
minimum of 0.013 in. insulation or wire nuts that cover
all exposed leads.
6. Make sure that all wire is contained within the base of
the smoke detector.
7. Program a Special Mode with the name FIRE RESET
to operate the fire reset relay from a programmable
output.
Four-Wire Circuit Reset Operation (Fig. 17).
Reset four-wire smoke detectors from the keypad by
entering the disarm code and pressing the FIRE
RESET mode numeric key.
The reset period is approximately 60 seconds, after
which the Fire loop is returned to service. During the
60 seconds, the power is removed and the Fire loop
is disabled. At the end of the 60 seconds, the alarm
condition will repeat if the detector still detects
smoke.
