Special Purpose Monitor (SPM) circuits are used for connecting abort and manual release switches
to the AutoPulse Z-10. For all applications, the maximum voltage (open circuit) is 28 VDC, and
the maximum current is 75mA.
Note:
In Preaction/ Deluge applications SPMs are used for Waterflow and Supervisory switches. In
combination Agent Release and Preaction/Deluge (Applications 10 and 11) SPM1 is used for Abort/Manual and
SPM2 is used with a pressure switch. Please refer to Table 1-3 for details.
The application type (i.e., single hazard or dual hazard) determines the function of each SPM, as
follows. The chart below refers to applications 1-4 only.
Application SPM Circuit Function
Single Hazard, Class A/B
SPM 1: Connect only abort switches.
SPM 2: Connect only manual release switches.
Refer to “Wiring Class A/B SPM Circuits for Single Hazard
Applications”.
Dual Hazard, Class A/B
Abort switches and manual release stations can share
SPM 1 and SPM2. An activated abort switch creates a current
limited state on the circuit, whereas a manual release station
creates a short on the circuit.
Refer to “Wiring Class B SPM Circuits for Dual Hazard
Applications” below.
Adhere to
Figure 3-5
and the following guidelines when wiring Special Purpose Monitor (SPM) for
a single hazard application. Connect abort switches to SPM1 and manual release stations to
SPM2. Do not combine abort switches and manual release stations on the same circuit. In
Preaction/ Deluge applications, SPM 1 is connected to Supervisory switches and SPM 2 to
Waterflow controls. As noted earlier, in combination Agent Release and Preaction/Deluge
(Applications 10 and 11) SPM1 is used for Abort/Manual and SPM2 is used with a pressure
switch.

Use only manual release switches that are UL-listed for fire use.

Use abort switch 433940 (flush mount).

Both manual release stations and abort switches must be normally open.

All wiring must be 12 AWG (max.) to 18 AWG (min.).

Conductors must test free of all grounds.

All wiring is supervised and power limited.

Leave 3.3 K, 1/2 W resistor across all unused SPM terminals.

Terminate Style B (Class B) circuits with a listed 3.3K, 1W (Part No. 431210) end-of-line
resistor.

For Canadian applications, attach the following resistor to a ULC-listed EOL device.

Part No. 431210 3.3K, 1W resistor

Terminate Style D (Class A) circuits at the Class A Adapter with a listed 3.3K, 1 W (Part No.
431210) end-of-line resistor. See
Figure 3-5
.

Maximum line resistance is 50 Ohms.

Normal condition (no devices closed). Current at 24 VDC: 6.0 mA

Manual Release condition. Current at 24 VDC: 25 mA

SPM Circuits do not support the connection of smoke or heat detectors.

When SPM wiring is routed outside the building, use Listed Secondary Protector 430685. A
protector must be installed at the building entrance such that protected wiring is segregated
from unprotected (outdoor) wiring.
