DSC PG9905, PG8905, PG4905 - Wireless PowerG Temperature Detector Installation Manual

Introduction

The PGx905 is a wireless PowerG detector for both indoor and outdoor applications. The detector monitors room temperature using an internal sensor. For outdoor or refrigerator installations, a waterproof temperature probe (optional) is used. The PGx905 can be used in instances where temperature detection is critical.
Other examples of detector usage are as follows:

• Activating and deactivating pipe heaters at locations where low temperatures may cause the water in pipes to freeze.
• Warn of possible electrical device malfunction due to high or low temperature levels.
• Alerting elderly people of a significant rise or drop in room temperature.

Features

• Internal temperature sensor
• An optional external temperature probe (PGTEMP-PROBE) enables outdoor and refrigerator temperature sensing
• Fully supervised PowerG detector
• Built-in link quality indicators reduce installation time by eliminating the need for the installer to physically approach the control panel
• Long battery life
• Low battery supervision
• Probe disconnected supervision
• Includes a "smart" anti-collision transmission sequence mechanism that prevents collisions with transmitted messages from other PowerG devices.

Operation

PGx905 series detectors update the alarm system control panel upon any change of temperature. Based upon the configuration, once a chosen temperature point has been reached, the control panel generates an alarm or warning message, sends a notification to the central station, and if configured, uses the PGM controls to switch on a connected appliance (e.g., a heater or an air conditioner.) When the temperature returns across the configured threshold, a restore message is generated.
When using the temperature probe, temperature measurements are only performed by the probe sensor. When the probe is not connected and its terminals are shorted, the temperature measurement is performed only by the detector's internal sensor.
For further reliability, the PGx905 tamper switch is activated when the detector cover is removed. Operating power is obtained from an on-board 3 V Lithium battery. A weak battery will result in a "low battery" message.
Note: When using the temperature probe to monitor refrigerator temperature, install the temperature probe inside the refrigerator and install the detector on the wall or ceiling. For outdoor installations, install the temperature probe outdoors, and install the detector indoors.

Device Setup

To be installed by service persons in non-hazardous locations only. Risk of explosion if battery is replaced by an incorrect type. Observe polarity when installing batteries. Dispose of used batteries according to the manufacturer's instructions and according to local rules and regulations.

Note: To ensure the continued operation of all wireless devices after performing a system default, a global upload of all wireless programming via DLS is recommended before defaulting the system. After completing the system default, download the wireless programming.

Install the battery

1. Insert a flat-edged screwdriver into the slot and push upward to remove cover.
   
2. Remove the screw and separate the cover from the base.
   
3. Observe polarity and install battery.
   
4. Connect the sensor wire to the terminal block. (Optional)

Note: When manually programming wireless devices, if a device has been powered up for more than 48 hours it cannot be enrolled into the system until the device has been tampered and restored. When programming the panel using the Quick Enroll procedure follow the steps detailed in Enroll the Device into the System.
Note: After restoring a low battery trouble the system may take up to 5 minutes to clear the trouble.

Enroll the Device into the System

To quick enroll

1. On a keypad press [*] [8] [Installer Code] [804] [000].
2. Press and hold the device enroll button until the LED lights steady and then release the enroll button while the LED is still lit. A confirmation message then appears on the keypad.
3. Press [*] key to confirm ID.
4. Enter [3 digit zone #].
5. Enter [3 digit zone type].
6. Enter [1 digit partition #] for all desired partitions and press [#]. If using an LCD keypad you can scroll to the desired partitions and press [*] to toggle the partition.
7. On an LCD keypad enter the label by using word library.

To pre-enroll

1. Remotely configure the unique ID number into the system. For more information see the HSM2HOST manual.
2. When on-site, press the device enroll button.

Note: If the wireless device has been powered for more than 48 hours without being enrolled, tamper and restore the device to enroll it.

Perform a placement test

Before permanently mounting any wireless device, temporarily mount the device and perform a Placement test.

1. Tamper the device by removing the cover.
2. Restore the tamper and the red LED blinks once to identify that a signal is being sent to the receiver and then blinks three times to identify the signal strength. To perform further tests tamper and restore the device. The following table indicates the received signal strength.

Only GOOD or STRONG signal strengths are acceptable. If you receive a POOR signal from the device, re-locate it and re-test until a GOOD or STRONG signal is received.

Note: For UL/ULC installations, only STRONG signal levels are acceptable. After installation verify the product functionality in conjunction with the compatible receivers HSM2HOST9, HS2LCDRF(P)9, HS2ICNRF(P)9 and PG9920.
Note: For detailed Placement instructions refer to the control panel Reference Guide.

Mounting

The PGx905 can be installed indoors on walls or ceilings and in any direction. When installing outdoors or on refrigerators use the temperature probe.
Mount the backplate in the monitored area as close as possible to the control panel to ensure optimum reception of the RF signal.
Note: Open probe terminals generate a "Probe Disconnected Trouble" transmission.
Insert the battery between the battery clips, at the correct polarity. For proper operation, only a Lithium battery (type CR123A) should be used.
Note: When replacing a battery, it is necessary to wait 30 seconds between removing the old battery and inserting the new one.
Note: Adhesive tape not to be used for EU Market.

1. Flex catch and remove PCB.
2. Mark and drill 2 holes in the mounting surface. Fasten base with 2 countersunk screws.
   
3. Reinsert PCB into base and connect the two wires of the probe to the terminal block.

Configuration

To enter the wireless configuration section enter [804][3 digit zone #].
