Device Information and Programming

m)Sounder Notification Module SNM800

This unit has a relay rated at 2A 30Vdc for switching external loads. Supervision of load wiring and the load supply is provided. The relay position is supervised and a “relay checkback” fault will be generated if it does not operate.

n)Short Circuit Isolator 5BI

This detector base is designed for isolating short circuited sections of the analog loop. For instance it can be used where the loop wiring crosses zone boundaries and it will prevent a short circuit from affecting more than one zone. As well as housing a detector it can be used with no detector inserted.

o)Sounder Base 814SB and MkII Sounder Base

These detector bases are designed as low cost warning devices. The MkII Sounder Base is a newer version of the 814SB. Some variants are loop powered while others are powered by an external supply. The sounder is controlled by the detector which is plugged into the base, but the operation of the sounder can be quite separate from the operation of the detector.

The 814SB can be setup to generate a number of tones (none of which are AS2220 or ISO8201 compliant), and three sound levels are selectable.

The MkII Sounder Base models can be setup to generate a number of tones including AS2220 and ISO8201 compliant evacuation tones, and on some models the sound level is continuously adjustable. Currently none of the MkII Sounder Base models are SSL listed.

Note that the current taken by a loop powered sounder base is very much higher than any of the other loop devices (except the LPS800), and the number of sounder bases on a loop is limited by the available current.

p)Relay Base 814RB

This detector base is designed for a low cost output device. It is controlled by the detector which is plugged into it, but the operation of the relay can be quite separate from the operation of the detector. A voltage two pole changeover relay is provided, rated at 1A 30V dc.

q)Loop Powered Sounder LPS800

This device is similar to the SNM800, in that it drives one or more external sounders, however the sounder power comes from the loop rather than an external power supply. The available output current is much lower than that of a SNM800, and as all this current comes from the loop, the number of LPS800s and their load is limited by the available loop current.

r)Vesda VLC800

The Vision Systems VLC800-MX VESDA Laser COMPACT is an aspirating smoke detector. It samples the smoke from air which is extracted via piping from a large area of a building. The sensitivity is adjustable over a wide range at the VLC800 by PC software programme. The VLC800 requires a 24V power supply.

A summary of the electrical specifications of the various devices is shown in Table 3-1.
