Installing the Hardwired Zones

Common Characteristics of Zones 1–8

•EOLR-

supervised

zones support both open-circuit and closed-circuit devices.

•As

many

4-wire smoke detectors

as can be powered from Aux Power on the control (zones

2–7).

•

Programmable

for 10, 350, or 700mSec response.

• 350mSec (default) should be used for most standard contacts. For vibration-type contacts,

10mSec is more suitable.

Wiring Burglary and Panic Devices to Zones 1–8

To wire burglary and panic devices to zones 1-8, perform the following steps, referring to

Figure 24. SL150 Summary of Connections

at the back of this manual.

Connect sensors/contacts to the hardwired zone terminals (8 through 20).

Connect closed-circuit devices in series in the high (+) side loop. The EOL resistor must

be connected in series with the devices, following the last device.

Connect open-circuit devices in parallel across the loop. The 2000-ohm EOLR must be

connected across the loop wires at the last device.

If the EOLR is not at the end of the loop, the zone will not be properly supervised, and the system

may not respond to an open-circuit on the zone.

High-Resistance/Short Supervision on Hardwired Zones 2–8

Special supervision in the control panel senses high resistance or a short on hardwired loops

2–8, causing a display of “CHECK” along with the number of the affected zone when the

system is in the disarmed state. The system cannot be armed when this condition is present.

If the system is armed when a high-resistance or short condition occurs, no display will take

place until the system is disarmed.

Wiring 2-Wire Smoke Detectors to Zone 1

1. Connect 2-wire smoke detectors across zone 1 terminals 8 (+) and 9 (–). Observe proper

polarity when connecting the detectors.
