Specifications

x Mount the center of the unit at a height of 2m with the PCB vertical setting at -4.

x Set the pulse counter to 2.

x Do not aim the detector at stairways that can be climbed by an animal.

x Avoid a location where an animal can come within 1.8m of the detector by

climbing on furniture, boxes or other objects.

INSTALLATION PROCEDURE

To install PIR sensors:

1. Open the housing by removing the front cover. To do so, insert a screwdriver in

the release slot (located at the bottom of the detector between the front and

back cover). Turn the screwdriver 90º to release the cover.

2. Remove the PCB by turning counter-clockwise and removing the Easy Lock –

do not touch the face of the pyro sensor!

3. Apply battery power by removing the isolator that separates the battery from the

contacts on the battery holder. (Note: Due to the occurrence of voltage delay

in lithium batteries that have been in storage, the batteries may initially

appear to be dead. In this case, leave the unit in Test mode for a few

minutes until the battery voltage level is stabilized.)

4. Place the Mode jumper over pins 2 & 3 (Radio Mode); the LED flashes.

Install the Mode jumper only after applying battery power.

5. From the Programming menu, select Devices, Zones [911].

6. Select the zone to which you want to register the transmitter; the system initiates

Registration mode. When Save? appears on the panel’s LCD display, press 9.

7. Remove the Mode jumper and place it over one pin for storage.

8. Choose an appropriate mounting height from Table B.1 and test the transmitter

from the exact mounting position before permanently mounting the unit.

9. Knock out the mounting holes and attach the base to the wall.

10. Mount the PCB at the required vertical adjustment and replace the PCB screw.

11. Write the number of the zone on the sticker provided. Affix the sticker inside the

front cover for future reference and replace the front cover.

Pulse Counter

Table B.3: Pulse Count Setting (MS845)

The pulse counter determines the amount of beams that need to be crossed before the

detector will generate an alarm. To set the pulse counter, refer to table B.3.

Adaptive Pulse Count

Using the Adaptive pulse count feature, the detector chooses between 1 or 2 pulses

based on its analysis of the received signal.
