Before Installing

Please read the system wiring and installation manual, I56-

407. This manual includes detailed information on sensor

spacing, placement, zoning, and special applications.

Copies of this manual are available from System Sensor.

General Description

Model 1251 intelligent ionization sensor uses a state-of-the-

art sensing chamber. These sensors are designed to provide

open area protection and are intended for use with com-

patible control panels only.

Two LEDs on each sensor light to provide a local, visible

sensor indication. The LEDs can be latched on by code

command from the control panel for an alarm indication.

The LEDs can also be unlatched to the normal condition by

code command. Remote LED annunciator capability is also

available as an optional accessory (RA400Z).

Wiring Guide

Refer to the installation instructions for the plug-in base

being used. As indicated in Figure 1, terminals for power,

ground, and the optional RA400Z Remote Annunciator are

included in the base. Base Models B210LP (shown in Figure

1) and B501 are electrically identical.

NOTE: All wiring must conform to all applicable codes,

ordinances, and regulations.

NOTE: Verify that all sensor bases are installed and that

polarity of the wiring is correct at each base.

Disconnect loop power before installing sensors.

1. Sensor Installation

a. Set the sensor to the desired address and record that

address on the label attached to the base.

b. Insert the sensor into the base and rotate it clockwise

until it drops into place.

c. Continue to rotate the sensor until it locks into the

base.

Dust covers are an effective way to limit the entry of dust

into smoke detector sensing chambers. However, they may

not completely prevent airborne dust particles from enter-

ing the detector. Therefore, System Sensor recommends the

removal of detectors before beginning construction or other

dust producing activity.

Be sure to remove dust covers from any sensors that were

left in place during construction as part of returning the

system to service.
